Rube Goldberg projects

Rube Goldberg was a cartoonist in the early 1900's who specialized in drawing complicated contraptions to do a simple task.  Today, people enjoy trying to build some of the cartoons he drew, as well as design their own Rube Goldberg type projects.  Our task was to create a complex way of throwing away a wad of paper.  The goal was to have 5 chain-reaction elements as well as 3 simple machines.  The only human interaction allowed was at the start.  Each group worked through the design process to dream of, draw, build, test, re-design, test some more, and evaluate their project.  Here are some pictures of the process!
