The Big Question: “Why will things change when you get older?” An anthropologist and real-life expert in prehistoric tool-making teaches Harrison how to make Neanderthal knife blades and to paint like a “cave kid”. Harrison invites kids at home to join him in making simple machines – a wedge, an inclined plane, and a lever - using nothing more than a sheet of paper. My Great Challenge: Contestants must figure out how to adjust a simple catapult in order to see who can throw a toy monkey the furthest. In the Field: Harrison takes on an assembly line robot to see which of them can put a car together the fastest.
