The answer to the Egg-Drop Competition.

I love Egg-Drop competition. It is a very interesting competition where the contestants devise clever ways to protect an egg dropped from around 100 feet high. They are evaluated on one thing:total weight of material used to protect the egg

And I claim here that I know the ultimate answer to this. 

Squeeze two balloons together, with an egg between them. Then permanently fix them altogether by taping around the balloons.
That's it. The total weight of two balloons and the tape used is less than 4 grams. It will win you the 1st prize ALWAYS. This works because the low weight density of the balloons serve as parachute. The system weighs 4 grams always, protecting an egg drop from 'any height' .
