A flying object that returns to its launcher has always attracted people. Although the term boomerang is primarily associated with Australia, such objects are also found on other continents. The classic boomerang is very labor-intensive to manufacture. It requires precision and competent selection of materials. In addition, boomerangs are considered by Russian law to be bladed weapons and are prohibited.
The proposed boomerang is made of paper and cannot cause any damage to people or furniture. In addition, its flight distance is only 1.5-2 meters, which allows it to be launched in an ordinary room. For all its simplicity and small size, it is a real boomerang that flies along a complex trajectory and has the ability to return.
Materials:
For manufacturing you will need the following tools and materials:
- Cardboard. You can buy it in a store or take it, for example, a box of chocolates.
- Pencil.
— A ruler at least 20 cm long.
- Scissors.
- Glue (optional)
Instructions for making a boomerang
1. Mark strips 20 cm long and 2.5 cm wide on a sheet of cardboard. Don’t be upset if the dimensions are not met. They can be changed within wide limits. If you have a large sheet of cardboard, then the boomerang can be cut out entirely.
2. Cut out the blanks.
3. Glue the strips in the center to form a cross. If you don’t want to glue, you can fasten it with a stapler. The perpendicularity of the parts is also not very important.
4. It is easy (without allowing the paper to crumple or bend) to straighten the blades and bend them to one side from the plane of the boomerang at a small angle. This is a very important point. The blades should not be twisted, as this reduces the flight range and distorts the trajectory. It is not necessary to give the blades any profile.
5. If desired, the finished boomerang can be painted.
The number of blades can be changed. You can easily make a boomerang with three or six blades. They will differ in their flight path. So, for example, a three-bladed boomerang has a slightly greater flight range than a four-bladed one, but is less stable.
Startup instructions
To launch, the plane of the boomerang must be perpendicular to the floor. The boomerang is held with the fingers of one hand, by any blade. The launch is made by flexing the wrist joint, so that the boomerang receives a forward movement, parallel to the floor, and a rotational movement around its axis. There is no need to put in much effort, everything needs to be done approximately the same as when launching a paper airplane.
Step 1. Materials and tools
It's very simple - some fiberboard or thick corrugated cardboard (your choice), some duct tape, and something to cut them with. It was a very short step, wasn't it?
Step 2. Design
I love making my own boomerangs because there are many shapes of boomerangs that will fly and they are nothing like the traditional L shapes.
If you can't come up with your own, then you can check out this great source for ideas on this topic. They are all designed to be cut out of plywood, but you can print one and trace the design onto your fiberboard.
One important point to remember is to round the ends of the wings - the boomerang will fly better and it will cause less harm to innocent spectators.
Very important note:
If you are left-handed, then you will need to make (and throw) your boomerangs in a mirror image of what I show here.
Step 3. Cut it out
Cut out your designs from cardboard and then cut off the narrow pieces that fit along the leading edge of the boomerang wing and lay them on top. This will support the tape to form the desired profile of the blade according to the wing type.
Step 4. Fastening
First, use small pieces of tape to secure the additional pieces. Then wrap the whole thing in duct tape. Try to avoid lumps and folds that will ruin the flow around the wing. That's it, the question is how to make a boomerang out of paper, solved!
Step 5. Flight of your boomerang
The boomerang throwing technique is described in great detail in articles and
Regardless of the shape of the boomerang you make, they are all thrown the same way. The written instructions in this project assume that you are right-handed, and will throw the same way - according to the instructions.
The best weather for a boomerang is calm or light wind. Stand facing the wind.
Hold the boomerang vertically in your right hand, between your thumb and index finger, with the curved surface facing you (thumb on the curved surface and index finger on the smooth surface).
Tilt the top of the boomerang slightly outward, swing your arm back over your shoulder, and then suddenly throw it forward. It is very important that the boomerang is released with a twist - if it doesn't spin fast enough, it won't come back.
Flight.
It may sound stupid, but boomerangs don't fly in a straight line. When they fly properly, they fly in a cyclic curve.
If you stand directly into the wind and throw a boomerang like that, it will be the farthest throw, but the boomerang most likely will not return to you. Throw your boomerang to the right, about 20-40 degrees from the direction of the wind (if the wind is blowing from "12" on the dial, throw in the direction of one to two).
Catching.
Let's hope the boomerang returns. It will tilt when it flies, and will be almost horizontal when it returns to you. This will increase the speed of its rotation, so the safest way to catch the boomerang is to slam it - slamming the boomerang with your hands as it flies past.
Safety.
Boomerangs are fun. This is cool. They can, however, pose a danger - spinning fast, moving fast, they can potentially cause serious injury, even if the boomerang is made of paper, to unsuspecting bystanders. Make sure that your flight will be safe for others, or at least that everyone knows that you are throwing an unpredictable object.
For very young visitors, I suggest looking at and making from paper according to the attached patterns - and
And again paper crafts. Today I will tell you, and most importantly, show you a diagram of a master class in the origami style - how to make a boomerang out of paper with your own hands. Initially, the homemade project seemed very simple to me, but it turned out that at the intermediate stage there were several very difficult and incomprehensible moments, which I will try to describe to you in detail. As always, we will need an A4 sheet, this time I took orange, for variety and beauty. No glue or other tools or materials are needed.
How to make a boomerang out of paper with your own hands
We put the leaf in front of us.
We bend it in half, along its long side.
It turned out to be two halves. Choose which one you like best.
Fold the selected half of the sheet in half again.
Then we unfold it and fold the bottom half along the edge towards the center.
Then we fold the top half.
Then we fold the workpiece in half so that the folded parts are on the outside.
Here's a side view of what it looks like.
Fold the corner on the fold side.
Then we bend the second corner.
Unfold the entire workpiece. We did this to create edges along which we will work in the future.
Here I will demonstrate the folds made closer.
Unfold the sheet of paper completely. You will see two identical squares.
Now comes the hard part. I tried and experimented with bends for a long time, I’m sure you won’t succeed the first time either. In the middle, the entire workpiece needs to be bent a little. And select one corner or edge, whichever is more convenient for you.
Then, we lean the part to the right of the corner against the main edge and tuck the whole thing under the left side, right inward.
This is how it should turn out. At first glance it is very difficult, but take your time and try to understand the meaning. We bend and tuck exclusively along the previously made lines!!!
We did certain things with one square. Now we do the same with the other one.
We’ll also flatten both sides of the central edge a little. View from above.
Here is an intermediate turn of the corner. This is more difficult to do since you need to tuck it inside the craft and you can use a long object to carefully insert it there.
We finally turned the corner inward. The most difficult part of the craft is over.
Top view of how it should look.
Take the boomerang, it's almost ready.
Now all that remains is to make the correct endings for the boomerang and the craft is completely ready. Left edge first. Fold in the top corner of the left side.
Then unscrew it back and wrap it inside.
We bend the opposite corner.
And insert the bottom corner inside the top hole. Or rather, a corner turned inward.
This is what we got.
We will do the right edge of the boomerang differently. Immediately fold the entire edge inward.
And carefully insert the lower part into the upper hollow.
This is what the result should be.
Top view of the second edge of the boomerang. the slope of the corners varies significantly.
The general plan clearly shows how the slopes of the corners differ.
Now you know how to make a paper boomerang with your own hands in origami style and according to what pattern.
I also advise you to try to implement , or .
Boomerang has always been more of an American toy that carried Western culture. Today, not only children, but also young people are interested in making it. The main feature of the boomerang is its mesmerizing rotation when thrown.
Making a traditional wooden boomerang yourself is quite difficult, but a paper model will be a more simplified alternative to making a popular toy. By following simple tips, you can put together a fun trinket without much effort. You will need one sheet of A4 paper. If you want your model to come out with more color, print patterns on it for a fun design.
Place the white side of the paper horizontally in front of you. Fold it in half and then unfold it. Cut along the middle fold so that you have two identical rectangles. Set one rectangle aside for another project. Take the remaining rectangle and fold it in half horizontally. Open the folds. Fold both sides towards the middle of the horizontal fold.
Your paper boomerang is ready. All that remains is to hold the model from above with your thumb and index finger at the bottom and throw it up.
Remember that rooms with high ceilings are best for boomerang games.
Throwing a boomerang can be an excellent way to spend time in nature. 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 differ from non-returning ones by a more curved shape, thinner 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 correctly launching a boomerang 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 on the reverse side, using your fingers, a more precise shape is given 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 the inner part of 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 self-adhesive film on it, 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.
