2. How much dirt is there in a hole 3m by 2m by 1m?
3. Throw a ball away from you. It stops (without touching anything) and returns to you. How?
4. A woman with no road tax or insurance goes the wrong way up a one way street, turns left at a no left turn sign. A policeman sees her. What does he arrest her for?
