Interactive Activity- Cold war?

what you can do is to set up two teams, start with two people, and have one person to gather a pen (as the weapon) and then the other side then gathers a pen, and it moves on with both sides gathering pens, but..you have have a "word" game collection with it..such as...you tell one person on one side a fact or a rumour and then have one person from one group to relay that fact or rumour to someone in the other group. then the facts and rumors build and pretty soon you have a disagreement among two parties and alot of pens. but then how do you resolve it all? by using a mediator and good communication and then agreeing to give up the pens. lol. good luck maybe?
