I have an egg drop project, in which we make a container on the ground that can cushion the fall of the egg. The limits are: 8 cm height max, and 45 x 45 cm box max area and the egg must not break even if it bounces out after hitting the container. It'll be dropped first from a height of 2 meters, then 4 meters. I got a 7 cm tall box and filled it with bubble wrap, and tried dropping it from 2 meters. Problem is, the egg bounces out every time and breaks when test out from 2 meters from . Is there any way I can prevent the egg from bouncing, such as putting something over the bubble wrap?
