A relay type skill race
Paper aeroplane for each Scout (they can make these themselves beforehand)
A line is drawn in front of the patrols with a circle for each patrol (about one foot in diameter) drawn at the other end of the room. Each Scout in turn has to fan a paper aeroplane into the circle. It has to come to rest completely in the circle.
When the second plane is fanned in they will find that other planes may be fanned out. All the planes must be in the circle before returning so the next scout can start.
The first patrol to complete the task wins.
