Description: Teams of up to 3 will build ahead of time a Rube Goldberg type device that starts by dropping a golfball to activate a pulley and ends by removing a toy car from the device. Additional points are earned for using simple machines as defined in the rules, as well as meeting other requirements. Teams must also submit a Simple Machine List (SML) that outlines the operation of the device. See the official rules for more requirements. THIS IS AN IMPOUND EVENT.

Materials: Teams MUST bring their device, safety spectacles with side shields, a writing instrument, and all tools/materials needed to set up their device. Parents may help carry the device in, but students must set it up and run it themselves.

Event leaders will provide the official scoresheet and all instruments needed to measure the device (meter stick, stopwatch, etc).

Scoring: High score wins. Points are earned for each successful use of a simple machine, as well as meeting other requirements as outlined in the rules. Penalties are taken for failure to meet requirements. Ties will be broken by: 1. Fewest penalty points, 2. Best operating time, and 3. Greatest variety of design.
