All these crazy contraptions are scientifically impossible! Could this be... witchcraft?
Professor Amos Todd
Amos Todd sells tickets to his Museum of Worthless Inventions when he sees a flash of light come through the rain clouds. He shows a gold making machine and then a power pill which converts water to gasoline. He is surprised when the water suddenly bursts into flame. In the storm he helps a doctor's car with a power pill and water. He finds all inventions now work and fixes the hospital generator with a perpetual motion machine. Back at the museum criminals steal the gold making machine. Todd follows using mechanical wings which stop working as he lands. All machines return to uselessness.
