MacGyver-O-Matic!
This event pits teams of improvisational engineers against each other and the clock to build an earth-shattering device out of discarded materials, duct tape and a Swiss Army knife. This year, compete to build an earth-smashing device.
This is an event to make flashy things and explain what they do with lots of verve, not Junkyard Wars where it has to actually do the job. Imagine the Illudium Q-36 Space Modulator from Duck Dodgers.
