1) Fill your balloons
Fill a number of water balloons.
2) Arrange your players
Get all players to stand in a circle looking inwards at each other.
3) Start throwing
One person throws a water bomb across the circle to someone else.
4) Expand the circle
If they catch it, without it exploding, all players take a small step backwards, widening the circle and the distance between players.
5) Keep on throwing
That player then throws the water bomb to someone else.
6) Expand again
If they catch it without it exploding, the whole group take another step back.
7) Repeat until the water bomb explodes
Repeat the steps above until the water bomb either explodes or the catcher misses.
8) Start again
The game starts all over again in a small circle with a new water bomb.
