Briefly, Travis points to some Rube Goldbegesque Flashy Flashness that’s guaranteed to bring a smile to yourself and waste at least 7 minutes of your time. It’s called the Blue Ball Machine, and has nothing to do with sexual frustration.

UPDATE: In talking about the aforementioned blue balls, I’d meant to reference the wonderful kinetic sculpture by George Rhoads outside of ScienceWorld.
