How to make a boomerang from paper or wood: step-by-step instructions. Instructions with videos and drawings on how to make a boomerang from plywood Coating the boomerang with a protective layer
An excellent tool spending time in nature can trigger a boomerang. This item originally served as a means of obtaining food among the ancient tribes of Indians, Egyptians, and Indians. Today it is simply a means of entertainment, made from various materials– wood, metal, plastic. You can make a simple boomerang with your own hands using paper or cardboard. We will look further at how to make a boomerang out of paper.
There are two types of boomerangs: returning and non-returning. The second type is a type of throwing weapon. Its length is approximately one meter, and its shape is less curved than that of the first species. Both wings of this projectile have a flat shape, reminiscent of the profile of a helicopter rotor.
Returning boomerangs will be of particular interest to children. They are different from those who no longer return curved shape, smaller thickness of the shoulders, reminiscent of the profile of an airplane wing. The angle of the shoulders is usually 70-110 degrees, and the distance between the two extreme points is 38-46 cm. The returning boomerang is lighter, so at the beginning of the launch it develops greater speed than the combat one. It is capable of flying up to 90 meters and rising to a height of 15 meters. The main condition for launching a boomerang correctly so that it returns back is to launch it in a vertical position. An origami boomerang can be made from paper or cardboard.
How to make a boomerang with your own hands from paper
It can be difficult to figure out how to properly make a paper boomerang that returns. However, everything will fall into place if you watch the master class on video.
To make this item you will need an A4 sheet of paper. It needs to be cut in half, determine the middle of this part, and bend it in half. Then return the sheet to its original state by bending each edge towards the middle. Then the paper blank needs to be folded in half, with the folded side bending the corners into a triangle. After this, the sheet unfolds, leaving only one side folded. Now you can see that a diamond has appeared on the unfolded part of the sheet. It is necessary to make it take on a clearer shape. To do this, the workpiece is turned over, and with reverse side fingers give a clearer shape to this rhombus.
The next step in how to make a boomerang out of paper is to form its bend. The workpiece unfolds vertically, with the diamond on the left side. Its lower part is pressed to the bottom, and then the entire part begins to bend to the left. On the right, the first bend is the edge of the workpiece. The resulting structure must be pressed downwards with your hand.
To make a boomerang made of paper durable, its edges are folded towards the central axis. The half of the right part must be bent so that the part forms a right angle. Then inner part The left wing of the boomerang needs to be folded into the resulting pocket, and then the body will be ready. To fix the two parts of the product, you need to fasten them with a paper clip. In order for a paper projectile to return, you need to bend the corners of each of its blades. To do this, open the edge of one of them, bend the corners towards the internal axis. Unfold the right corner and bend the cavity inward. The left corner is unbent, its edge is inserted inside the resulting hole. Similar actions are carried out with the second wing. In order for the boomerang to come back, it is important to throw it correctly: taking the projectile by the edge or the middle of the corner, turn your hand when throwing.
A boomerang can be made from cardboard with several blades (three or more). Blade templates can be found on the Internet and printed on a printer, then glue the paper onto cardboard or simply transfer the outline onto it. The blades are glued together in the center, overlapping each other. The recommended length of each blade is 17 cm, width is 3.5 cm. All angles when gluing must be 90 degrees.
A two-bladed boomerang can also be made using a template. To do this, you need to draw a template on checkered paper, then cut it out and transfer it to cardboard. If you stick a colored one on it self-adhesive film, this will give the projectile additional rigidity and beauty. The blades of the projectile must be bent so that in profile they resemble a flat figure eight. To launch a projectile, you need to grab the corner with two fingers of one hand, and then click the blade with the fingers of the other hand. When launched, it is capable of rising to a distance of up to three meters in height, then returning back. If you expand the blades even more, this will change the flight path of the cardboard boomerang.
To understand the technique of how to make a boomerang with your own hands, it is best to watch visual diagrams or videos on the origami skill.
Not everyone knows that a boomerang is, in fact, a type of throwing weapon. wooden weapons. But the days when it was used as a weapon are long gone. Today it is a toy that not only children, but also adults want. We will tell you how to make a boomerang with your own hands.
Boomerangs have become widely known for their ability to return to the place from which a person fired. But there are also boomerangs that do not return (combat boomerangs).
What other boomerangs are there?
A – combat boomerang; B – “pil-pil”; B – “Kylie” boomerang, which, like the “pil-pil”, can return, but only if thrown against the wind; G – sports and hunting returning boomerang; D, E – multi-blade returning boomerangs.
DIY boomerang
You will need:
- Sheet of cardboard;
- Plywood or wood;
- Varnish or paint;
- Jigsaw;
- Plane;
- Sandpaper.
First of all, you need to draw the selected boomerang model exactly in life size on a thick and thin sheet of cardboard. It is recommended to choose a sheet size of 50x60 cm. After this, you need to transfer a grid with a square side of 50 mm onto the cardboard.
Next, we redraw the outline of a boomerang onto it from the drawing shown in the figure.
How to make a boomerang from plywood
From the resulting template, we cut out a blank from plywood. Its thickness is 10 mm.
Now you need to process the workpiece. This should be done with a small plane in a vice or using the device shown in image (d). The boomerang needs to be planed starting from the middle, moving towards the edges of the blades. Their end should end up being 6mm thick. The blades must be absolutely identical in shape. To simplify the task, you can make counter-templates of the blades from plywood and apply them to check the correctness of the shapes.
The surface should be completely smooth, so the next step will be sanding. To do this, you can use sandpaper. After sanding, the almost finished boomerang is coated with a primer, and then with varnish or paint. Best to use bright paint, so that the boomerang can be seen from afar and is easier to find when falling. In addition, parquet varnish can be used for coating, which preserves the aesthetic structure of the product. This is how you can relatively easily make a boomerang with your own hands in an hour or two.
How to make a boomerang from wood
If possible, it is recommended to make a boomerang from wood. For this purpose, as a rule, bent branches and roots are used. It is important that the wood is dense, heavy and well dried. The following materials are suitable for making a boomerang: oak, birch, beech, linden. The manufacturing process is exactly the same as in the case of plywood. But it should be remembered that wood deteriorates much faster than plywood, so it must be varnished or painted especially carefully.
If you followed all the rules when creating a boomerang, then it will have excellent flight qualities and a beautiful appearance. We figured out how to make a boomerang with our own hands, now we need to figure out how to launch it correctly.
How to launch a boomerang correctly
1. Place to workout
Launching a boomerang for the first time, despite all its apparent simplicity, is quite dangerous due to unpredictability, so some caution and attention will be required. You can hit someone with a boomerang, so you shouldn’t start experiments in crowded places. Optimal place to train agility and accuracy - a meadow or clearing with a radius of 40-60 meters (the more, the better). In a city, such a clearing could be a football field or a vacant lot.
The launch of a boomerang is specific in that its flight trajectory is a figure eight. Therefore, the person throwing the boomerang should throw it only from the center of the place chosen for training. The projectile will fly forward, making a loop in front of the thrower. He will then return and make the same loop behind the thrower, thereby forming a figure eight, the execution of which depends on several parameters - the force of the throw, the quality of the boomerang, the experience of the thrower.
2. The key to success is the correct grip.
The boomerang has two main surfaces. The convex front side, on which, as a rule, a design is applied, creates its own effects when rotated. The back side, in most cases, is flat, you can also see a pattern on it, but with proper throwing, usually only the front side can be seen.
It is customary to hold a boomerang like this: thumb always lies on the front side. Holding a boomerang correctly means holding it facing you and seeing the pattern clearly.
The boomerang can be held with both the wing backward and the wing forward. This is not important and in any case it is correct - whatever is more convenient for you.
Boomerangs can be light or heavy. You can determine the type yourself - your hand will tell you which boomerang you are holding.
A light boomerang in your hand needs to be fixed with three fingers - it is clamped with the middle, thumb and index fingers(It should be recalled that the thumb should always be on the front side when gripping correctly).
It is quite difficult to hold a heavy boomerang with three fingers, so it needs to be fixed in the fist, right up to the little finger, i.e. the grip comes out with four fingers, so the fixation is quite rigid. You can grab it deeper, but when throwing the boomerang it will be awkward to release, so it is not recommended to grab heavy boomerangs deeper than four fingers.
3. What angle should your hand have?
Many beginners launch a boomerang on a subconscious level, tilting it like a sickle used to cut grass, almost parallel to the ground. This is completely wrong. In a boomerang, the aerodynamics are designed so that throwing it correctly means throwing it almost perpendicular to the horizon, at the same time the inclination to the horizon line should be to the right of the imaginary perpendicular. The boomerang should be released at an angle of no more than 45° to the horizon during the throw.
You can come to this experimentally on your own - if the boomerang is tilted too much, it will fly up sharply, and then also dive sharply to the ground in front of the thrower. If the throw is made at an angle of more than 45°, the boomerang will never even come close to returning to the thrower.
4. What should the throw be like?
The boomerang should be thrown sharply and forcefully. When launching a boomerang, you need to take into account the fact that the projectile requires force not only to fly away from the thrower, but also to travel back and loop behind the thrower. Therefore, you should throw extremely hard and sharply, especially if for training you use a real wooden boomerang, and not a toy plastic copy. As a rule, the first throws are timid and cautious, especially if a woman or child is throwing. But don't be afraid! Any high-quality boomerang is designed for a powerful throw, because if you throw it weakly, this will lead to its rapid fall somewhere along the trajectory, which is not very good for it.
You need to throw the boomerang straight in front of you, looking and focusing on the horizon line. There is no need to throw the boomerang up - it is better to throw it straight forward, because the design of the projectile is such that it will independently gain the required height.
5. Spin the boomerang
During the first throws, a situation may arise that you, as it may seem to you, are throwing the boomerang sharply and strongly, but it still flies smoothly, without twisting as required. In this case, you need to master some spinning skills. If you throw the projectile correctly, it will spin as quickly as a propeller - the pattern will merge into a solid circle, the blades will not be visible. To ensure maximum spin, a good grip is essential. In addition, the boomerang should not be buried too much in the fist (the correct grip was described above).
There are many ways to spin a boomerang, but we will focus on the simplest and most common.
So, we swing and throw sharply, but at the very last second before the boomerang comes out, you don’t let go of your hand completely, but quickly stop it, as if pulling it back. Many of us have used mercury thermometer, so this movement is familiar to everyone - it completely repeats shaking a thermometer.
With such a throw, we leave a kind of trip for the boomerang, cut off the running leg and he, stumbling, rolls head over heels. A boomerang twisted with such a stopper will twist more strongly.
6. Wind accounting
We figured out how to launch a boomerang, but we should also take into account the wind. Wind is almost the main factor that influences the flight path of not only a boomerang, but also of all flying projectiles and devices. Its influence should be taken into account when throwing no less than the force of the throw and the correct grip. If the wind is very strong, sharply changing direction and strength (intermittent), it is better to postpone the training and practice the theoretical part again. It is better to start training in calm, windless weather or in light wind that does not change direction. If you are making throws in the wind, then it is recommended to direct the throw towards the wind slightly to the right of its movement. With such a throw, the wind will help the boomerang return to the thrower. Among other things, the wind has a strong influence on the accuracy of the return of the projectile, because the behavior of any aircraft depends on available air flows. You can make friends with the wind, but this comes only with experience and after numerous trainings. It is simply impossible to comprehend this art the first time.
Let's sum it up
Let us note the main rules for handling a boomerang:
- The boomerang should be thrown from the center of a deserted place with a radius of at least 40-60 meters;
- For a proper grip, the thumb should be on the front side;
- When throwing a boomerang, you need to tilt it to the horizon from 90° to 45°, otherwise the projectile will simply stick into the ground;
- The correct throw is sharp and strong, pulling back. In this case, the boomerang twists well;
- If you are training in windy weather, then the throw should be directed against the wind slightly to the right.
Only perseverance and patience, dedication and perseverance will help you gain some experience and learn how to throw a boomerang correctly. It can fly perfectly in both winter and summer, you can always practice, but it’s better not in deep snow conditions.
Throwing a wooden boomerang is an ancient method of communicating with the world and surrounding nature. If you practice persistently, you will soon be able to understand wind, air currents and other elements of nature. Over the years, many people have successfully mastered this art and continue to learn it.
You have successfully been able to familiarize yourself with the theoretical part by reading this manual, so it’s time to move on to the important and main part - the practical one. Practice and experience will teach you the art of boomerang throwing, bringing unique pleasure from the process of unifying with the world around you.

Instagram's Boomerang app makes simple moments fun and unexpected. Create captivating mini-videos that automatically scroll forward and backward, and share them with your friends. The application will take 10 photos in a row and create a wonderful mini-video from them.
Well, this won’t surprise anyone, right? When “Boomerangs” first appeared, they managed to bore everyone, because everyone decided to show their creative efforts, as with Prisma. The trend has subsided, and now I use Boomerangs as a test of the account’s audience. Making a one-second video is very simple and quick, and the end result is a snapshot of the account’s organic reach, making you cry and hug your knees.
But the situation is such that all the latest “boomerangs” show sad results, and the posts after them are not in demand (personal observations). Whom to kick and scold?
The other day I watched one relatively useful webinar, in which I heard information that was very useful for myself, which I did not know before. Perhaps I am a complete layman, but the following statistics were a small discovery for me.
Instagram counts video views of 15+ seconds as “previous interaction experience.”
What does it mean? Videos traditionally receive fewer engagements, provided your account isn't all video content. Those. by uploading a very short video/Boomerang, you get fewer likes and video views do not count toward previous interaction experience, therefore, the organic reach of subsequent posts will be underestimated.
Those. When you publish a short video, you cut your organic reach to the quick, you can even hear it shrink. This is in theory, but I don’t see any other option here.
It turns out that you need to post longer videos, but at the same time dynamic, such that users should want to watch them to the end.
But not every social media manager and business owner received an Oscar last week for best screenplay and cinematography, which means that the videos, in most cases, turn out to be crap. And they don’t watch them anymore.
But I want a video...
Let's use Boomerang! More precisely, A LOT OF BOOMERANGS.
What have we done? We went out for a walk and in 10-15 minutes rented a carriage of these same Boomerangs, without really thinking about the goal.
The next step is to carefully combine them into one video. I, like a person of the old school, immediately went into my Pinnacle Studio and most likely would have buried me there if it weren’t for mobile applications for video processing. I had practically never worked with them before, so I checked everything at random.
The vast majority of them can do 2 of the 3 necessary functions:
- Video editing
- Music overlay
- Normal format without cut edges
Almost everywhere the final video is produced in a “classic” style with huge black fields around the edges in a 1x1 format.
I was lucky enough to stumble upon the Quik app (no ads), available on both iOS and Android. It works even better on the green robot, because... There is a function for overlaying your own music downloaded to the phone. And this is much easier to do in pirated Android. After all, who pays for music these days?)
And so, boomerangs are ready, there is an application, and then it’s a matter of technology. We choose the theme of the video, mix the boomerangs, add music = the content is ready.
Of course, the video is far from perfect. It could have been made more intense, with fewer repetitions of the same moment, added colors, etc. But all the manipulations took a total of 30 minutes, which included a walk on fresh air, record video, search for applications and music.
If the built-in video does not work for you for some unique reason, you can watch a video example
What do we get as a result?
Very fast and dynamic content, easy to develop and “unhackneyed” format. Another plus, not obvious at first glance, is that in this format you don’t need to say anything, and many people are embarrassed to do “this” on camera.
The range of applications is as wide and varied as possible:
- Show the “fashionable look” in motion from all sides.
- Present a new product/product in your store.
- Present your business with services, sales, or whatever.
- Use the video for advertising on Instagram.
- Digest for the year/month.
- Arouse envy with your travel to beautiful countries. Watching you walk around the cathedral for 30 seconds is boring. It’s interesting to see how you walked around Barcelona in 40 seconds.
In any case, without doing similar experiments, a thorough understanding of the mechanisms affecting coverage will not come soon.
Successful experiments and audience involvement!)
The long-awaited summer has finally arrived. Time for picnics, beach volleyball and fun activities. But sometimes it happens that we get bored playing football or riding bicycles while walking. How to be? What to think of? How about making a boomerang and spending your free time in an unusual way?
If today we look at the history of the Egyptians, Indians, Moroccans and Navajo Indians, we will see that for these peoples the boomerang was not an object of entertainment, but a weapon with which they obtained food for themselves. Today, the boomerang is no longer a weapon, but an object of entertainment and interesting pastime.
So, let's get down to how you can make a boomerang yourself? What material is best for this?
How to make a boomerang out of paper with your own hands?
Origami paper boomerangs are a simple and quite interesting pastime. Your children will especially enjoy this activity. Simple scheme origami boomerang will allow you to fold not just an ordinary figurine, but a small toy that will not only fly, like a paper airplane does, but can return back to your hand.
1. For a paper boomerang you will need a sheet of A4 stationery paper. It is best to take a regular landscape piece of paper, which is a little thicker than regular office paper. Fold the sheet of paper in half lengthwise.
2. Take scissors and cut the sheet along the fold line. Now all your work will be connected with only one half of the leaf.
3. Fold the half of the leaf in half again lengthwise and smooth the fold with the tips of your nails in order to secure the fold as tightly as possible. Now turn the fold back.
4. Fold each half of the sheet in half and smooth the fold again with your fingers. Try to bend the halves of the sheet inward so that their edges do not reach the central fold by one or two millimeters.
5. Now you need to fold the sheet in half, but not lengthwise, but crosswise. Remember that the seams, after bending, should not be on the outside, but on the inside.
6. Once you have folded the paper in half and are sure that the seams are in the middle, turn the shape so that the fold line is on top. Now you need to bend one and the second edge of the sheet into a triangle and walk along them with the tips of your nails. This way you will fix the folds.
7. After you have folded the triangles from the edges of the sheet, turn them back and bend them inward. You should have a triangle on top.
8. Now you need to unfold all the origami to the state of stage four. The figure you should get is shown in the ninth diagram. Then unscrew the right half of the folded leaf, as shown in the tenth diagram. It is especially worth paying attention to the folds of the diamond. Carefully walk your fingers along the fold lines.
9 . According to diagram eleven, you must bend the triangle inward. Press with your finger inner side rhombus Next, bend the sides inward, a triangle should come out of the rhombus, fold it in half.
11. The end result should be a curved piece of paper in your hands, which in its outline will resemble the shape of a boomerang.
12. Now you must first bend the bottom of the sheet lengthwise, and then do the same with top part origami.
13. Note the overlap in the middle of the boomerang. Open the boomerang slightly, pull out the bottom left part and overlap it with the bottom right part.
14. When you have an almost finished boomerang in your hands, you should pay attention to the position of the edges of the fold lines. This point is worth considering, as it will play a decisive role during boomerang throws.
15. Now we form two corners along the edges. Fold both ends of the boomerang into a triangle, smooth it with your fingernail, then unfold the triangles and bend them inward.
16. The boomerang can be decorated, made from colored paper or wood. The type, material and final shape of the boomerang will depend only on you and your imagination.
How to throw a boomerang?
You probably won’t be able to throw a boomerang correctly the first time, so don’t be upset and sad, be prepared for training.
You don’t need to throw a boomerang with your whole hand, but only by turning your hand. During the throw, all the force should be transferred to the hand so that you can throw the boomerang as far as possible.
You should also hold the boomerang correctly, otherwise you won’t be able to make a real throw. Hold the boomerang by the corner in the middle or by the edge. However, the position of the fold line should be taken into account. The fold line of the top of the boomerang should be at the top, under your fingers.

How to make a paper boomerang come back?
If the boomerang does not return to you, there are three reasons for this. The first reason is that you violated the boomerang manufacturing technology. The second reason is that you are holding the boomerang incorrectly. The third reason lies at the heart of the throw itself. If you do not apply force to your hand, then the throw does not work correctly, and therefore the boomerang does not have the strength to return.
VIDEO. How to make a boomerang out of paper?
Previously, people needed to hunt to feed themselves and everyone who lived with them. They used many tools for hunting. Some of them are still hunted by humanity, others have become sporting equipment, such as bows and crossbows. However, hunting was also carried out with the help of a boomerang. This is a very interesting projectile, now let’s look in detail at how to make a boomerang out of wood so that it looks exactly like a medieval weapon. And then we will create copies for children that are easy to make at home.
Why does a boomerang fly farther than any thrown object?
Many people do not understand why boomerangs fly so far. It's all about the structure of their blades. They are made on the principle of an airplane wing. That is, the lower part is flat, and the upper part is convex. Different pressure is formed, which pushes this wing up, allowing it to stay in the air at a certain speed.
Why the boomerang is coming back
You can understand how to make a returning boomerang only by studying its geometry. We figured out why it takes so long to fly. Now how does he come back? The thing is that the boomerang blades are different in length, one is longer than the other by a sixth. However, if you hang a boomerang at a corner, you can see that the long blade will be the same in weight as the short one. Thus, when the boomerang rotates, its long blade receives more air resistance than the short one, because of this, with each rotation it moves to the side. Having understood the theory, you can begin to understand how to make a boomerang. Now all that remains is to reproduce everything in the material.
What kind of wood to make a boomerang from?
To make such ancient weapons you need solid material:
- Ash
- Pine
- Poplar
This will make a great boomerang. You need to find a branch that is shaped like the letter “G”. If a living branch is cut down, then you cannot immediately make a product from it. The material must dry, only then can you begin to work. Drying wood takes a lot of time, so it’s worth preparing the material in advance and then making a boomerang out of it. However, you can use a dry branch or plywood one centimeter thick. However, here we are looking at how to make a boomerang from wood, not plywood. Therefore, I will explain how to dry the workpiece.
Drying wood to make a boomerang
After the required branch is cut down, its annual rings need to be covered. To do this, use garden pitch, resin, you can even fill it with PVA glue. In general, this is done to prevent moisture from escaping very quickly through the cuts. This way, the wood will dry out gradually and there will be no cracks in its structure. The material should dry for at least six months, but in general, a year would be good. But you can reduce this time to a month. Let the workpiece lie “sealed” for a week, and then you need to remove the bark from it, leaving only rims of a centimeter or two at the ends of the cuts. Then the material must lie for another two weeks in a dry place, after which there is nothing left but to make a boomerang with your own hands and test its aerodynamics.
We are starting production of boomerang
We need a tool:
- File
- Sandpaper
- Jigsaw
- Hacksaw
Our log needs to be sawed in half to make two pieces similar to the letter “G”. You can even make two boomerangs or more if the wood is not defective. In short, we cut the material into pieces one centimeter thick. To accurately observe the shape and size of the product, you need to make a template for it. And we have no choice but to make a boomerang out of cardboard, or rather, the outline of the product will be made from it. After which this template needs to be pasted or simply attached to wooden blank and carefully circle. Having a line for precise cutting, you can not be afraid to cut off excess, and we cut out our future throwing weapon along the contour. This can be done with a jigsaw or trim off the excess with a knife, the main thing is how to make a boomerang, and not sharpen it with anything.
Making a boomerang lift
When the contour is perfect, we begin to form the convex parts so that the product can stay in the air. The picture shows all the thicknesses of the boomerang. You need to do it exactly like there. In order not to make a mistake with the dimensions on each surface area, you need to make patterns. Segments are cut from cardboard to depict the shape and the exact size of the convexity of a particular part of the boomerang. After this, they are cut out to create patterns. By applying them, it is easy to see how much you need to grind.
Boomerang alignment
We have mastered everything regarding how to make a boomerang, but it still cannot fly as it should. In order for the product to return when thrown, it must be centered. To do this, you need to make a loop of thread and thread a boomerang through it so that the blades point down. When the product is not centered, the longer part of it outweighs, but it needs to hang perfectly evenly. This can be achieved by grinding the material, or by drilling a small hole in the smaller blade and pouring glue into it, inserting a piece of lead. In this way, the workpiece is brought to perfect balance, after which all these ancient weapons are polished.
Coating the boomerang with a protective layer
When used, a boomerang often falls to the ground; the material from which it is made saves it from blows. It's made of hard wood! But in wet weather, how to make a boomerang protected from external influences nature? After all, if its surface is “open,” then the appearance can significantly deteriorate. Dirt sticks well to untreated wood. But more importantly, moisture can deform the entire structure, or even create cracks. To protect the product, it must be waxed or varnished.
Waxing requires wax; it is mixed with turpentine and then rubbed into the surface of the product. You can also simply rub in the wax using a rough cloth. But you need to do this by pressing firmly with sharp movements so that the wax melts from friction and is absorbed into the wood.
The surface can also be varnished. It must be applied in a thin layer so that droplets do not form. After the first applied layer has dried, cover with the second. So, you can do it four times for best protection products. When all the protection has dried, you can start testing the boomerang in the field.
Now let's look at how to make a boomerang out of paper
This is a great toy for kids, and they can make it themselves. So, let's start in order.
- You need sheet A-4 as tightly as possible. Place it horizontally in front of you and bend it in half away from you. So that the length of the sheet remains unchanged, and the width is doubled. We cut it in half, and in the future we work only with one half.
- We bend it in half lengthwise and carefully smooth out the bend. Then we unfold the sheet and bend its left half towards the central fold, one centimeter, without reaching it. Then also with the right side. The halves should be bent in half, and a central bend should be visible between them. To understand exactly how to make a boomerang out of paper, we use the diagram
- In this position, fold the sheet across all bends exactly in the middle of the sheet. Then on this line we turn the corners to the middle, as when we make an airplane. After this, we unfold the corners and tuck them inward along the bend lines.
- Then you need to expand this origami until the left and right side were bent towards the central bend. Unscrew the right side, in its center the fold lines in the form of a diamond will be visible. Pressing it with your finger, you need to fold it along the bends so that you get a triangle. It should be inside, and the entire structure will be bent in half. Everything is clearly outlined in the diagram.
In ancient times, boomerangs were made mainly for the reason that they flew further than any other object that a person threw, and only closer to our times they began to make them so that they also returned to the hands of the thrower. And they were able to explain that return effect only when they mastered aerodynamics and the first planes flew.
