Keeping the balls out of your part of the hall
Many bean bags, ball pit balls or paper balls
Divide the room into two halves and have a team in each.
A number of bean bags, ball pit balls or rolled up paper balls are given to each side.
When the game starts the players try to kick or chuck the bags/balls as fast as possible into their opponents half.
When the signal is given to stop the players immediately freeze (award a penalty point for any movement) and the number of balls in each half is counted.
The team with the least number in their half win.
