Divide children into two or more teams. Team members stand one behind the other and each leader is given a balloon.
The balloon is passed down the line by going over the leader's head to the next child who passes it through their legs to the next one who in turn passes it over their head.
When it reaches the last child he/she runs around to the front and starts it off again.
The game continues until the team leader ends up back at the front and the first team to finish is the winner."
