You will need:
An old plastic 2l pop bottle, 3/4 filled with earth or sand.
Chalk or two chairs.
Two tennis balls.
A large space to play in with a flat floor.
How to set up:
At each end of your hall either place a chair or make a mark on the floor, this is where the throwers stand.
In the centre of the hall (equal distant from both ends) place the bottle on a mark.
Split the group in half.
The two teams sit on each side of the hall.
Number each of the members of the team i.e. 1 to 10 if you have 20 in total.
How to play:
The leader calls a number say 5.
The two players who are number 5 race to their ends of the hall and pick up a ball.
They must stand behind their line and throw it at the bottle in order to knock it over.
The players can use any ball but must stand behind the line to throw it.
Award a point to the team whoes player knocks the bottle over first.
Re-set the bottle and call another number.
