For example:
Preparation materials: raw eggs, scraps of paper, small paper boxes (larger than eggs), canvas (square and slightly larger as long as it is airtight), string, paper tube (you can use your own paper roll, the thickness is similar to that of a pencil).
Process:
One: Buffer device:
1) Put the scraps of paper into the paper box, which is about the volume of the paper box 1/3 (function: absorbing the impact force).
2) put the eggs in, and then put the scraps of paper, not too little, but more important, that is, when the carton is sealed, it is best to shake the carton without feeling the eggs moving. At this point, the carton packaging is completed. (function: prevent eggs from tumbling in the air)
3) Fix the paper tube on the edge of the paper box with transparent glue, so that the paper tube can contact the ground before the paper box falls to the ground, which plays a buffering role.
Two: deceleration device: 1) Tie the rope to the four corners of the canvas.
2) The other end is fixed on a top corner of the paper box (note that it is the same top corner).
Third, put down the device and use the parachute to increase the air resistance, so that the egg and the whole device can land smoothly.
