Any advice for egg drop project?

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.

Any advice for egg drop project?
This is a lot more stringent than when I did mine, so I only have a few suggestions.





1. Make sure one part of the device is heavier than the rest, so you can control how the device lands (I used a film container filled with change)





2. The closer to the top of the device the egg is, the less effect impulse will have on the egg. (more impulse will lessen the pressure of the drop)





3. Make sure the egg is vertical when it lands (eggshell is stronger vertically than horizontally)





4. Try to use something with a sturdy outer frame, so the frame will absorb the impact instead of the egg (mybrother used a soup can, and it worked amazingly well)





Hope this helps, enjoy.
Reply:What about spring?


You can suspend the egg on a spring or a number of springs inside the box..





Another idea : are you allowed to tie a rope to the box. You can then tie the other end of the rope to a counter weight through a pulley.
Reply:I would use a weight to control the balance of the drop, and small bungee cords or rubber bands to control the shock of the impact.


The more you can contour to the egg the better but I think they are trying to get away from a contour type protection.





But a shock absorbing carrier is what you need.
Reply:never forget the triangle it will win just use a bunch of triangles. layer the bottom with pyramids, and around where the egg will go, then do the top like the bottom.
