Team building game where the Young People try to cross a river(Hall) (using chairs/carpet tiles/any odd equipment, as stepping stones).
Chairs, any odd equipment or carpet tiles
The Young People have to get from one side of the hall to the other, at the same time. So they start on one side, with all the chairs (there should be less chairs than Young People), and then gingerly place a chair in front of them, stand on it, pass the next chair to the front person, and kind of leap-frog along.
When each team completes the task, remove an item, and go again. keep removing until only two left. This extends the game. Great fun with two teams racing each other. Remember, they need to get ALL the chairs and themselves across, each time, without stepping in the middle. One step down and the whole team starts again!
