How to make a decompression toy?

Prepare a big plastic cover, a cap screw, a piece of paper, three colored pens, a pair of scissors and a glue stick, and then make a small gyro according to the following steps.

First press the cover on the paper and draw a circle along the edge. Draw a small circle in the circle. This small circle is where the screws are to be threaded next. Draw a yellow and black snake on the paper with a colored pen, then cut it off with scissors, make a hole in the middle of the cover with scissors, and also make a hole in the middle of the snake picture with scissors.

Stick a piece of paper on the cover with a glue stick, put the screw through the hole in the middle, and then screw a nut on the back, and the little gyro is ready.

You can hold the top in your hand, hold the nuts at both ends and turn the cover with your fingers. At this time, the snake kept turning.

You can also remove the screws at the back, lengthen the screws at the front, and then put the gyro on the table. When you screw the screw, the top will spin quickly. After a while, the snake on it will disappear.

Although this little toy is not very big, it can relieve people's stress to some extent and achieve the purpose of decompression.

Decompression initially means that when the workers return to the outside world from the pressurized state of diving and the air passes through the sealed cabin or the pilot ascends to heaven, the ambient air pressure decreases, which later leads people to reduce or relieve the pressure.
