Objective Build a device that will propel a raw egg a maximum horizontal distance and have it remain intact.
Participants Teams of up to six.
Materials Provided by the team: A launcher constructed by the team prior to the competition. An unmodified device such as a tennis racquet will not be allowed. Egg protector and catching device. Safety glasses.

Provided by the Science Olympics Committee:
3 large grade A eggs.


1. Each group will build and bring with them to the competition a mechanical device to propel a raw egg a maximum horizontal displacement. Throwing by arm is not allowed.
2. No other aids are allowed; e.g. football goal posts cannot be used as a part of the launcher.
3. No explosives, combustible fuels or compressed gases are allowed.
4. The raw egg may be contained in a protective encasement.
5. A catching device may be employed.
6. The competition will be staged out-of-doors, regardless of the weather.
7. Each team will have three shots. The longest surviving shot will be scored.


Your distance score is your longest distance travelled in three trials, and contributes up to 75 marks.

Your score = 75 (Your distance)/(Maximum distance)

15 points are awarded for the design and construction of the launcher and 10 points for the catcher.

In London , this event was one fifth of the Grade Ten Pentathlon. The five events are:
Add 'em 'up.
Circuitous Circuits.
Cryptic Cross Word.
Metric Madness.

World Record The entry in the Guinness Book of World Records related to this event reads as follows:

EGG throwing: The longest authenticated distance for throwing a fresh hen's egg without breaking it is 96.90 m 317 ft 10 in by Risto Antikainen to Jyrki Korhonen at Siilinjarvi, Finland on 6 Sep 1981.
