Snake Eyes: A Rube Goldberg Device Matt Burnett, Jenn Kranyak, Daniel Moody & Sony Sam

Purpose The purpose of our device is to roll a pair of dice.

How it works… A water cup and a cup of sugar are sitting on opposite ends of a see-saw. They are filled so that the water cup weighs more. We begin by uncovering a hole in a cup of water. As the cup of water empties, it gets lighter.

How it works… The sugar side of the see-saw falls. The wire under the see-saw connects to the metal plate on the pizza box and completes the circuit.

How it works… The completed circuit is attached to a length of fishing line. The copper wire heats up, which burns through the fishing line.

How it works… The tension in the string is released, which causes the cup to fall. The dice spill out of the cup, and are rolled!

Energy Conversions Gravity – potential to kinetic Chemical/heat

Conclusions Our group worked well together We ran into a few problems, but through brainstorming and teamwork we were easily able to solve them.
