Ever wonder how those whacko's got onto that reality show? Despite having succeeded at the game, we don't know either. But for the curious, here is the tape that worked for us. We were the first Americans to appear on the engineering competition Junkyard Wars (Scrapheap Challenge to the rest of the world). This is the deluxe version of what we sent them.
Ever wonder how a sewing machine works? See a larger than life model constructed, and the operation demonstrated using adult humans as the working parts. (aka stupid human tricks)
Nerds speak - Have a Nerd speak at your next event. Or host your own Junkyard Wars style competition - Makes a great team building exercise. See http://www.the-nerds.org/lecture.html
