Physics Egg Drop Project?

Question

Well, I know that the egg drop is a fairly common project among physics classes, but while we were supposed to research possible designs, I found very few to suit this criteria.
-The mass of the device (w/o egg) cannot exceed 100g.
-Materials are limited to:
2 sheets of paper, 2 paper towel tubes, half of a 2-liter soda bottle, string, rubber bands, straw, and tape
Any suggestions?

Oh, a few additions.
The eggs are supplied (I can't pick a small one).
And no packaging, essentially nothing soft to pad the landing, is to be used (although I can get around that).

Answer 1

I'd suggest making a sort of parachute with the sheets of paper, then cramming the t-liter bottle full of straw. Find a method of securing it all together with the tape and strings, then away you go! The "parachute" would slow the descent somewhat, and the straw would cushion the impact.

They've kind of dealt you a losing hand by restricting the project so much, though. Luck will play the primary factor in everyone's project. When they had us do it in middle school, we had no limits at all!

Answer 2

Make a parachute out of the paper.

Make like a gondola with the bottom of the 2 liter bottle.

Suspend the egg inside the gondola with the rubber bands.

When the device is released, the paper-chute will create wind resistance, slowing it down as it decends to earth.

The paper-chute might not slow the device down enough to prevent the egg from breaking, so that is why you suspend the egg inside the gondola with the rubber bands. To absorb what force is left after the chute reduced it.

If assembled so that the egg does not break loose from the rubber bands, the egg will not break.

Answer 3

First cheat. Find the smallest egg that you can. This will help a lot. Then arrange your egg packing with these principles:

You need to arrange for the surrounding material to crumple as this will absorb some of the shock. You need to support the egg evenly to spread the impact and reduce any stresses. You might want to reduce the speed by adding a basic sort of parachute. It doesn't need to be very efficient, it just needs to slow down the fall a bit.
