Battle of the Candles

Requirements:

Split the troop into two equal sized teams facing each other on opposite sides of the hall. Give each Scout on each side a number from 1 to n where n is the number of Scouts on each team.
The idea of this game is to blow out your opponents candle. Each team has their own candle positioned at one end of the hall. When you call out a number between 1 and n then the two Scouts with that number from each team runs out and picks up their candle. To win the game they have to blow out the other Scouts candle while keeping their own alight.
If you have a lots of Scouts then to stop the other Scouts getting bored while it is not their turn you could add more candles to each team and call out more than one number each time. If the Scouts are crafty enough then they could work as a team for example by re-lighting each others candles if they can.
