This is a very simple tournament style mixer.
Supplies:
None.
How to Play:
Have everyone find a partner. Each person stands with both feet together, facing each other, arms length apart. The object of the game is to get the other person to lose balance. This can only be achieved by pushing your opponent's hands. Hands do not have to maintain contact. Often times a player will act as if he is about to push another player's hands and then immediately pull away so as to cause his opponent to lose balance.
After every pair has decided a winner and a loser, have those who lost sit and the winners stand. Then have each winner find a new partner. Rinse and Repeat.
