Why do boomerangs come back?

Presenter Greg Foot investigates why boomerangs return to the thrower. He explains the shape of the boomerang is like a plane’s wing that generates lift and that the spinning boomerang acts as a gyroscope. Greg then explains how gyroscopes work and demonstrates the gyroscopic procession that results in a ‘hands-free’ bicycle turning and a correctly thrown boomerang moving in a curve to return to the person who threw it.
