The first of six programmes with Johnny Ball
A light-hearted exploration of science, technology and numbers. This week Johnny discovers Wheels Within Wheels
Round wheels, not-so-round wheels, oval wheels, big wheels, little wheels; and a chance to see how you can go backwards while going forwards! Plus an eccentric bike and the newest engine that goes straight round the world.
Meanwhile, see if you can get around to solving this one. Cut up a circle into 22 parts using only six straight lines.*
