Take part in a game or activity with your pack wearing earplugs or headphones so you can't hear clearly and use your pack scarf as a blindfold.
Create an obstacle course that is fairly simple and not too dangerous.
Pair brownies up and in turn get a brownie to navigate her partner around the course. This can be made harder by getting the Brownies too carry a tennisball on a bat or carrying a bean bag on their head.
Alternatively, any physical activity ie Skipping, Relay Race, Bouncing Balls can be used instead of an obstacle course.
