Travel across America with host John Bowler as he ventures into gadget-filled garages and junk-strewn backyards to meet amateur inventors who are making amazing(ly weird) things! Test-drive a jet-powered minivan, a fire-breathing wheelchair, a water-powered rocket belt, and more. Once we've seen what these 'mad scientists' are capable of, John challenges each inventor to improve one of their creations, and, with his help, build the coolest, weirdest thing they can think of.
