Have everyone find a partner. One person is blindfolded, the other is leading. The one who is leading, needs to take the other through a obstacle course of some sort (it can be natural or made). But they can not touch they have to do it all by words only. To make it more difficult have an entire group lead one person and take turns. (It is a lot more chaotic).
Requirements
blind folds of some sort... even spare cloth will work
