How should I build an 18in. long or wide egg capsule without a parachute and make it survive a 20-story drop?
Answer:
I did something like this before...
Mine was smaller, but making it bigger will make it even stronger and better.
I took this thick foam and cut an egg shape out of it..
I placed the egg in the foam, then placed it in a larger container with packing peanuts in it.
So, I made a foam case around the egg...then taped it so the egg would not fall out, and placed the foam case in packing peanuts. Mine was off a four story building, but during the testing and practicing for it...I chucked it really hard against a wall and nothing happened...
Good luck
If this doesn't make sense...feel free to email me still =]

If someone told you how to do it ,do you feel you really learned anything?
If you must cheat, why dont you do a search for "egg parachute" or "egg drop" on the FunQA.com . I see this question every time i come here.
You haven't said what your building material is. I know of one school that used drinking straws. The goal in this situation was to use enough straws to both slow the decent via drag and to provide a crushing surface on the bottom that would cushion the impact. A parachute is the most efficient way of producing drag but there are other ways if the material is light enough. Think of something like a dandelion seed but also with projections on the bottom as well.
If you don't get enough drag with just projections you might think of making it spin like a maple seed. Spin works great for reducing drag even in multi-ton helicopters.
remember Jolt = force X time. Change in momentum (Jolt) will always be the same but if you increase the time of the collision the force will be less.
