Brian Hubert

Energy

He began inventing at age 8, when he invented a machine that would convert the weight of water into electrical energy while it sat on the ocean floor.
He also invented the "Cheater Meter" - this is pocket-sized device that tells customers if they were being cheated when filling up at the gas station.
Other inventions included trash bags that remain straight in a trash can and cups that allowed you to drink beverages while upside-down!
