Contestants typically win egg drop contests by keeping their eggs unscathed when dropping them from the height specified for each contest. Variations of the contest also give points for the design of the safeguarding apparatus, its mass and how close it drops to a target landing point.
Egg drop contest participants are usually given a specific duration to create their apparatus from a limited set of materials. The trick behind the contest is the knowledge and application of physics, specifically in free fall. The egg-protecting container or apparatus must be able to cushion the impact of the fall by taking factors such as the height of the drop and the total weight of the egg and container into consideration.
