Any advice for egg drop?

Project Criteria: The size of a shoe box. ~The protection for the egg must be engineered, not just filled with stuff.~No type of packing material will be allowed. This includes but may not be limited to such items as : bubble wrap, cotton balls, tissue , styrofoam pellets, cronstarch pellets, pillows, stuffed animals, shaving cream, paper, ballons or egg crate foam. No type of food may be used as packing material. This includes : jello, marshmallow, popcorn, or peanut butter,~ No wooden or metal boxes~No parachutes or helium filled balloons will be allowed~The egg will be provided at the time of the drop which you will then have to insert it into your project~ No boxes will be accepted that are preloaded with an egg. And it must have physics behind the design. Including Newtons laws of motion, terminal velocity, momentum, and gravity.





Thanks for the help ahead of time.

I guess the rules didn't say the project had to be of your own conception.
Reply:if you have a Cloths Dryer i would use the lint out of the Lint Trap
Reply:Take a box full of eggs to the top storey of the highest building in your school.





Lob them into the stair well, one at a time. eventually a member of staff will stick his head into the stair well and be just missed.





The trick is getting your face back before he looks up and recognises you.





If you get caught, you can always claim to be practising for your physics experiment. It will wind up the teacher of an arts subject more than can be described.
Reply:Easy, just put an antigravity device inside it and it'll fall nice and slow. Now all you have to do is invent an antigravity device.
Reply:Secure a weight to the small end of the box. Use tape or rubber bands to firmly secure the egg to the middle of the other small end of the box. The idea is to have the box land flat on the heavy end so the collapse of the box absorbs the energy of the fall. You may want to use something the weight of an egg and do some experiments to determine how much weight is needed to make it reliably fall onto the heavy end.
Reply:My suggestion would be to make a propeller for the top so that as it falls the propeller catches the air and slows it down while keeping it stable. I've done this a few times with my classes and the propeller works best, as long as there is no penalty for longest hang time. Since the air will be providing a force up, the net force on the system will be far less than mg so the acceleration will be small (Newton's 2nd). The impact on the ground will be small if the impact velocity is small, because the change in momentum will be smaller than hitting the ground hard (Newton's 3rd and Impulse=change in momentum) If the propeller catches enough air resistance, it will reach its terminal velocity much quicker and at a smaller value (terminal velocity).
