How to make a boomerang 65 from paper, how to make a boomerang from paper

Teach you to make a boomerang out of paper.

Postcards or cardboard, protractors, scissors.

Production process: 1. Draw a pullback mark with an angle between 90 and 120 degrees and a length of 5 cm and a width of 2 cm on the cardboard.

2. Cut off the return force mark, then the return force mark is completed.

How to use: 1. Use your fingers to hold the outside of the angle of the force marker.

2. Flick it with the other finger to see if the force mark can fly out smoothly.

3. When the raw hand is launched, the return target can fly out smoothly, that is, it is completed, and as for returning to the original point, it needs to be practiced.

Scientific principle: 1. The force mark is a zigzag bending, when we hold one end of the force mark and rotate it forcefully and throw it forward, due to the force of rotation and the force caused by the force when the two sides of the force mark rub the air, the force mark will use rotation to wipe the air, and it will make the force mark fly in a special curve after leaving the hand.

Boomerang is really fun and teaches you how to make boomerangs.

Hold the rope in one hand and quickly throw the wood and quickly withdraw the rope after smashing the target.

Note: Don't pull the wood back and smash it on your head!!

The inner corner of the dart seems to be for all.

It's better to ask the physics teacher about this...

How to make a boomerang made of paper is as follows:

Prepare a square piece of colored paper, fold it in half up and down, left and right, align the four corners and fold the midpoint, align the adjacent sides and fold the rock angle line inward, and fold the upper corner outward into a triangle, fold it in half, fold out 16 such shapes, insert these shapes one by one, and the boomerang will be folded.

Here's how to do the boomerang:

1.Prepare thicker drawing paper (. White book covers or thick paper shells are available at stationery stores. 2.Place the thick drawing paper at the bottom, then put carbon paper on top of it and pattern paper on top.

3.Slide the ballpoint pen along the curve of the paper to trace the shape of the dart. Don't forget to add dotted lines.

4.In order to distinguish between heads and tails, mark the front note in advance. 5.Use scissors to carefully cut out the dart pattern on the thick drawing paper. 6.Place the dart pattern on the table and lay it flat.

7.Align the ruler with the dots and lines and use a ballpoint pen to make 2-3 strokes vigorously. This is done to facilitate folding.

8.Fold the wings into a mountain shape. The angle of the fold is 10 30 degrees (if you fold with your left hand, fold it into a valley shape).
