Elasticity

Find a partner and face one another
Move around anywhere in the room but keep eye contact with each other
when leader shouts "change" you must change partner
Experiment with levels, distance, pace etc

Comment: This requires a certain amount of trust in the group to be able to maintain eye contact but is a good way of finding out the groups closeness.
This is a good spacial awareness exercise working with a partner and being aware of those around at the same time.
