Get a spool of string or yarn. Each person has to answer a question of some sort when they have the string in their possession, but when they throw it to another player they have to hold onto the string/yarn and keep holding it so the ball of string/yarn unravels on it’s journey.
You eventually create a web of some sort and at the end can use this to describe how the web is analogous to the group in that we all played a part in creating the web, and that if one person was gone it would look different. Likewise, it is important that we all take part to make the group what it is, unique and special.
