This game is particularly good at family parties or with mixed age groups, and is definitely a warm weather game!
You will need:
2 plastic bottles Small plastic cups
Divide the players into two teams. Choose a good sport (perhaps a parent) to sit, cross-legged, with an empty plastic bottle on their head.
Line up the rest of the team and give the first in line a small plastic cup. Fill up a few large buckets with warmish water and place them between the team members and the good sport.
At the signal, the first team member runs to fill up their cup and then pour it, quickly but carefully, into the plastic bottle. Either continue until one bottle is filled up, or call time and see who has collected the most water.
Give the good sports a towel, and the winning team a prize!
