Egg Lob
Objective Each team must build a device which will throw an egg (size Large) as far as possible. Only the energy which can be stored in two rubber bands (size #64) can be used in this device. Each team must also develop a method of protecting the egg to prevent it breaking when it hits the floor.
Participants Teams of up to six.
Materials Any material may be used, as long as the egg can be inserted into its protection just before launching and
easily removed for inspection after the flight.
Rules

1. The egg must survive the lob unbroken, defined as having no fluid leaking from the egg.
2. Any broken eggs must be cleaned up by the team responsible.
3. The egg may not be altered in any way. This includes coating the egg with some substance such as glue to prevent its being broken.
4. Contestants shall use an egg provided at the competition. The egg must be loaded within 10 minutes of launching, and must be removed for inspection after its flight.
5. There can be two separate devices; one acting as a launcher, and one acting as protection. The rubber bands do not need to move with the egg.
6. Rubber bands will be supplied 10 minutes prior to the event.

Judging

1. A barrier approximately 10 cm high will be placed 1 metre from the start line. Any eggs which do not clear this barrier will be disqualified.
2. The team whose egg travels the greatest horizontal distance from launch to impact will be the winner.
3. All other teams will be ranked according to the distance travelled.

  Contestants are required to clean up any mess that results from broken eggs. Any egg which leaks fluid will be considered to be broken. In London we have a No Egg rule because of the difficulty of cleaning up.. We found broken eggs in interesting places.
