How long will your paper hand last?
Here is an effective way to stimulate friendliness, have a lot of fun, get everyone acquainted in an informal way, and put the participants in a party mood.
As each person arrives, the leader presents him with a paper lunch bag and a rubber band and instructs him to place it over his right hand and secure it with a rubber band. Players move around the room greeting and shaking hands with as many others as possible.
The "winner" is the first person to wear out his or her paper bag – not by tearing but by shaking hands!
