There's a new show coming to the SciFi channel called MasterBlasters. I know a few of the guys that have been working on the series and it should be loads of fun to watch. Sort of a cross between rocketry, junkyard wars and american chopper.
For example heres a clip from the challenge to launch a cooper mini and make a field goal.
The clip incorrectly states its in next weeks episode, but it has been pushed back, next week they recreate the wizard of oz and launch a house.
