How do you protect an egg that will fall from 20 feet?

Answer 1

In elementary school we had a competition like this where we had to make something that would protect an egg being thrown of the gym roof( 30ft).

I took a bleach jug and cut a door/flap( top/bottom/one side) that I could open reach through to place the egg. The plastic was stff enough to spring back to hold the door closed. I lined the interior with bubble wrap. I placed 4-5 full layers on the bottom, then I placed layers that had a hole in the center to hold the egg snugly in place. I left enough room so I could still grab/remove the egg. I then made a hole in the cap were I tied stings that ran up to a parachute I made out of plastic( painters drop cloth). The parachute needs to be cut in a multi point star shape so it opens properly. You can test it without the egg to adjust the string length.

The end result was so well thought out, it could have be deployed from a plane and not break the egg.
