well, it's not mythbusters or junkyard wars, but it's not bad

Today while watching Japanese TV, I found a really interesting simple engineering show. The participants have to design and create a simple machine powered by rubber bands. Then, they have to get it approved by judges or compete in some kind of challenge. All of the machines are essentially useless and made from hooks, spools, lumber (or occasionally metal), and rubber bands.
For one challenge, they had to design and build a rubber band gun. Instead of creating a commercial/infomercial and presenting to judges (the goal of about half the challenges), the engineers used them to shoot little statues of sumo wrestlers on wheels to make them fight. Whoever's sumo wrestler wins, won the challenge. It was awesome!

I marked down when the show was hoping to catch it again next week!
