Here's a cute challenge from geometry ...

Suppose you are given a circle. Use only a piece of paper and a pencil to locate the exact center of that circle!

In this video I show you how to find the exact center of a flower pot, or of the lid of a jar of jam, or of a quarter. It's fun and represents a neat way to motivate some standard results from the curriculum.
