This Too Shall Pass

I stumbled upon this video by OK GO. I really like it because in middle school I have been on a team that created one of these " Energy Transfer Contraptions". I was (and still am) a big science geek. An energy transfer contraption competition challenges students to use inventions to transfer from one energy source to another in order to reach a goal.

In the case of this video the goal is to spray the Band Members with Paint.
Notice how the energy can be as light as pouring water to as powerful as bowling balls and cars.
