  • Machine must have a minimum of 7 steps and a maximum of 15 steps. A single step is defined as a transfer of energy.


  • Ball rolls down a ramp and springs a mousetrap
  • The mousetrap pulls a string causing a scissor to cut
  • The scissors cut a cord, causing a weight to fall
  • Weight drops on tin foil, causing light bulb to turn on
    • At least 3 of the steps must use a simple machine (lever, screw, gear or wheel and axle, pulley, inclined plane, or wedge)
  • Contact Kat Leo at 845-344-1234 or for more information or with any questions.

    About Rube Goldberg:
    Rube Goldberg Machine is a chain reaction-type machine or contraption intentionally designed to perform a simple task in an indirect and overly complicated way. Usually, these machines consist of a series of simple unrelated devices; the action of each triggers the initiation of the next, eventually resulting in achieving a stated goal.
