Variation 1
This variation is great for including everyone:

1.  Ask participants to stand around the circle, spaced equally from one another.

2.  Once in position, their feet become stuck in place and they cannot move for the duration of play.

3.  Introduce the activity as before.

This variation increases the level of attention and cooperation as participants must pass the yarn from person to person to complete the task. This variation also keeps the more extroverted crowd from dominating the activity.

Variation 2
This activity can also be fantastic when the winding is done by hand:

1.  Use multiple rings and ask the group to wind them down as fast as possible, again with the fewest touches.

2.  Or, try it in pairs where each ring must be wound to the bottom by two participants,who must hold on to the ring at all times.

3.  Whichever you choose, vary the size of the rings to pose a challenge to your specific group.
