Today, the spirit of Rube Goldberg's cartoons continue with Rube Goldberg machine contests. In these contests, competitors design a machine to perform a mundane task in the most steps. List some possible actions and devices you can use in a machine that you would make for this contest. Remember that the entire machine must be started by using only one motion.

I can't think of any actions or devices I could use... Can someone please list some ideas? Thanks a million (=
