Balloon Games

Sit on chairs or stand in a circle.
Introduce a balloon and instruct the group to pass it around the circle without holding it and without it touching the floor.
Introduce another balloon and tell the group that at any time a person can take hold of the balloon and walk to someone in the circle say their name and hand it to them after they have too said their name back.
You can add more balloons to the circle and if the passing of the balloon around the outside is too difficult to sustain at the same time then people can simply walk with the balloon to someone else and say their names.

Once there are a number of balloons in the circle the challenge can be given to the group to keep all the balloons up in the air without holding them for any time. Each time a balloon is batted up into the air the person calls out their name.

Variation
Have only one balloon in the circle and like the game above someone bats the balloon up into the air but then calls out someone elses name in the circle. They must then come in and stop the balloon hitting the floor while calling someone elses name in the circle and so on..
