What you need:
Four buckets and two plastic cups.
Get two groups of three or more players and line them up next to each other. All players should be sitting on the ground.
Put the full bucket of water in front of the first person in each row.
The first person in the row scoops up some water in their cup and then balances it on their head, the person behind them has to take the full cup of water and put it on their head (try not to spill!). Once the cup reaches the person at the back of the line they empty the water (what’s left) into an empty bucket behind them.
The team with the most water in their bucket wins the game!
