Get your balloons to the finish line first.
4 round balloons
Divide the group into two teams, then divide each team into pairs. This is a relay race, and the racecourse can extend across a large field or around a building. Mark a start and finish line. Teams of pairs space themselves equally from one end of the racecourse to the other. Pairs stand back to back with elbows linked. Blow up 4 large balloons and give two each to the first pair from each team. One balloon is held in each hand of each player. When the leader says "Go", the first two pairs make their way to the next pair of linked players. The first pair transfers its balloons to the next pair. The first team to cross the finish line wins.
