For this game, you will need several skeins of yarn. Divide the group into teams (works best if there are at least seven on a team) and give each group a skein. Each group is then instructed to create the most authentic-looking spider web by forming a circle and creating the web in the middle of the circle by passing and tossing and otherwise working together to create a yarn web. This is a challenging game that requires forethought and cooperation.
