America is full of inventors, but none like Bob Partington. Each week Bob will receive three objects, all of them connected to America's innovative past. Bob's task is to use each of the objects in fun, never-before-seen inventions. Whether he makes an invention to help a stranger or a local business or devises something cool for himself, it's up to Bob to use the objects to carry on America's true spirit of invention.
In this episode Bob uses a conveyer belt, charcoal and a bike chain to make three unique inventions. Bob stumbles across a neighborhood block party and builds an invention that leaves everyone yelling for s'more.
