Wife and daughter set off to Sheffield to watch Miranda this afternoon.
This is what me and the boy did with some balloons, food colouring, a pin and my camera:
First attempt - balloon of water hanging from a tree punctured by home made dart (end of a shoe lace and a pin - haven't made one of those for ages!) fired through a straw (if you look closely you can see the dart on the left of the balloon/water!:
Second attempt balloon on table punctured with pin on end of chopstick yellow food colouring added - camera set to burst:
Quite impressed I managed to capture the 'ball' of water just after the balloon was punctured!
