Ball game where teams have to keep the ball out of their area by throwing it into another team's area. A whistle is blown peridically and a point is recorded against the team that has the ball at the time. The team with the lowest scors at the end of the game wins. Add extra balls for more chaos, but be sure to have enough people spotting to keep track of all the balls.
One or more balls
A way of dividing up the meeting place into halves or quarters
Get the Cubs or Scouts into either two or four teams. Doing it in sixes or patrols works well.
Split the hall into playing areas using chalk, or tape etc.
Throw the ball into one area to begin.
Blow the whistle every twenty seconds (faster for a more frantic pace to the game)
