A la Rube Goldberg, this rediculous contraption dubbed "Falling Water" was built by Joseph Herscher who, by my guess, must either not be employed, be an idiot savant, not have a girlfriend, or "D" all of the above. In any case, it is really cool to watch.
This is another contraption he built in order to smash a Cadburry Cream Egg called "Cream That Egg." At the end of the video he states that the video was made, "With Support from The World's Most Tolerant Flatmates, 30 Sticks of Hot Glue, and 480 Pints."
