Evidence of Work
So what exactly is a Rube Goldberg machine? Well, it is a machine consisting of a bunch of simple machines ( such as levers, pulleys, wedges, and more ) and chain reactions. For our Rube Goldberg machine we used 5 out of 6 possible simple machines to activate a "That was easy," button: a lever and fulcrum, pulley, wheel and axle, inclined plane, and screw.
