A question for the engineers....

My buddy dropped the egg and I think he was so sure we'd win he didn't really pay attention and the thing bounced off the side of the plastic laundry basket and smashed on the pavement.

We lose.

We had to drop eggs from the top of a grain elevator in high school physics.

From what I remember, we the following materials to use:

styrofoam solo cup
a pipe cleaner
2 popsicle sticks
2 playing cards
2 feet of string
2 rubber bands
1 coffee filter
some scotch tape (maybe 6 inches worth?)

All of the rest of the class attempted to make parachute type devices that worked with varying degrees of success.

I designed a helicopter type device that translated some of the downward energy into rotational energy. The blades were made from playing cards attached to the popsicle sticks. I made a sort of cradle for the egg by making a stretched and suspended rubber band base inside the cup. On top of the rubber bands was the wadded up coffee filter. The egg sat on top of that. I held the egg in place pointy side down with the pipe cleaner. I thought the pointy side down would translate more energy through the shell parallel to the length of the shell instead of perpendicular to the shell (if that makes sense - send the force up through the shell instead of across it). Anyhow, mine was one of the two that actually worked.
