If you’ve entered an egg-drop contest, there are basically two strategies you can use to help that egg survive a fall. The first is to cushion the impact, and the second is to reduce the speed of the fall. If you get to choose your own egg, you can soften it with vinegar to help it absorb the impact. That will help, but by itself, it won’t prevent the egg from breaking.
Cushioning the Impact
Enclosing the egg in something that can absorb the force of impact can protect the egg from a fall. You’ll need something that is highly compressible for this.
Water won’t do the trick, nor will soft solids like peanut butter or sugar, or any incompressible liquid or powder. A gas is compressible, though, and air is a gas, so anything that contains a lot of air should work. Possibilities include balloons,
popcorn, packing peanuts, wads of paper or cereal puffs. Encase the egg in any of these inside a paper or plastic bag, a sock or a stocking. If you have any bubble wrap around the house, wrapping the egg in several layers of bubble wrap should also provide a good cushion.
Slowing the Fall
Slowing the egg’s fall is key for keeping the egg in one piece, but slowing does not take the place of protecting. Parachutes, for example, make things fall more slowly,
but if you’ve ever seen a parachutist land, you’ll know that the impact can still be jarring – jarring enough to break an egg. This means that, if you create a parachute for the egg, you still need to protect the egg.
You can also try tying several balloons to your egg before dropping it instead of building a parachute; they should slow the egg’s descent. Aerodynamic rotors,
such as those on a propeller beanie, can also work. The weight of the egg actually makes the rotors spin faster to slow its fall. If you make the rotors just the right size, the egg may fall slowly enough to survive, even without added protection.
