Egg Drop
Objective To design and construct a container which will hold an egg, and will prevent the egg from breaking when it is dropped to the floor.
Purpose To explore the physics of collisions.
Participants Teams of two.
Materials Foam, Styrofoam, urethane or any similar material.
  1. The container to be prepared in advance will be a carton that can be modified to some extent, but may not exceed the dimensions 7 cm x 7 cm x 15 cm.
  2. Only masking tape will be allowed on the outside of the container to reinforce the structure. A piece of magnetic material will be provided.
  3. One end of the package must contain a piece of magnetic material to allow attachment of the package to the electromagnet - minimum diameter of 2.5 cm.
  4. No parachutes or auxiliary attachments other than masking tape will be allowed on the outside of the container.
  5. The egg must be placed inside the container and handed in to the "Launch Master".
  6. A grade A medium egg shall be supplied to each entry. The contestant will have ten minutes to insert the egg and prepare for competition.
  7. The package will be attached to the release mechanism by means of the magnetic material (8m above the platform).
  8. A 1.3 m square landing platform will be provided. The package must strike the platform. Impact on the platform will stop the timer.
  9. If the package misses the platform, a second trial will be allowed. In the event of a second miss, the participant will be disqualified.
  10. The package must be opened and the unbroken egg produced within three minutes of the impact.
  1. The egg that remains unbroken is the winner. In the case of a tie, the container that weighs the least will be the winner.
  2. Another criteria can be the length of time taken for the package to fall.
