He used 4 tyres and two motors, the egg rests between the tyres and the motors turn the tyres which in turn turn the egg.
As he was trying various methods out he was using a plastic egg which was jumping about a lot, the problem of the escaping egg was solved when he added a real hard boiled egg, the weight of the egg stopped it from jumping.
