How to make Daquan video by hand?

Hand-made paper planes are as follows:

Tool: A4 paper.

1. First, prepare a piece of A4 paper without crease and fold it in half, as shown in the following figure:

2. Fold one corner and the other corner, as shown in the figure below:

3. Then fold the two corners inward, as shown in the following figure:

4. Then turn back to the opposite side, as shown in the figure below:

5. Fold out two small corners and open them, as shown in the figure below:

6, and then turn the triangle up, as shown in the figure below:

7. Finally, fold it in half and fold out the wing of the plane.

An airplane refers to an aircraft with wings and one or more engines, which is driven by its own power and can be denser than the air in the atmosphere. If the density of an airplane is less than air, it is a balloon or an airship. If there is no power device and you can only glide in the air, it is called a glider.

A paper plane is a toy plane made of paper. Probably the most common form of aviation origami, it belongs to a branch of origami. Because it is the easiest type of origami to master, it is deeply loved by beginners and even masters.

Principle: The power of paper airplane flight comes from the kinetic energy when it is released. After flying, if the height of the plane remains the same, the air resistance will gradually slow down the speed of the plane, and the paper plane will exchange the potential energy of gravity for the kinetic energy of progress.
