20 1 1 On July 7th, my parents and I finished an homework-throwing eggs on the fourth floor. Because I live on the fourth floor, I started working at home.

Now start the experiment. Preparation tools: eggs, boxes, foam, tape paper, knives, etc. Get the tools ready and we'll start working. Eggs are easily broken, so throwing them directly will definitely break them, so my parents and I made them with the above tools: first, take them out and put them in a fresh-keeping bag, even if they are broken, they can be eaten. Then cut the foam into boxes with a knife. Then dig a hole the size of an egg in the foam, put the egg in it, and then put the foam in the box. Finally, tie the box tightly with tape paper and complete the "installation".

Start throwing eggs below. I went to the balcony and threw down the box containing eggs. After throwing it away, I couldn't wait to go downstairs and run home with the box. When I got home, I carefully opened the box, took out the eggs and looked at them carefully. There is no gap. I'm glad the experiment was successful!
