The egg drop contest is an experiment usually performed by college or primary school students. Competitors typically attempt to create a device that can keep a raw chicken egg intact when dropped from a height. Students are asked to build a device made from a limited or unlimited amount of materials to support an egg when dropped from various heights.
Naked egg drop
A variation of the egg drop competition is the naked egg drop, in which an exposed raw egg is dropped into a container below that must catch the egg and keep it from breaking.
Another common variation on the egg drop competition is the egg hurl competition, where the containers are hurled by a device such as a trebuchet or air cannon. This variation is often used by schools that lack tall structures from which to drop the containers.  The egg hurl variation adds additional difficulties to the design of the container, since it is initially hurled at high speed and has to cope with horizontal as well as vertical velocities upon landing.
Often schools work together to make larger competitions that pit more students against each other. One of the larger regional egg drop competitions is the Winston-Salem / Forsyth County Egg Drop Competition that takes place during Engineers Week (late February) each year.
