Roo's Whoopty-Dooper Bounce

1

Mark out a line with 2 old t-shirts, a piece of string or a stick.

Then take a long run up, jump when you get to the line and mark how far you got.

3

Take it in turns to see who's got the biggest bounce.

4

Try jumping without doing a run up, or try doing a one-legged jump.
