Participants in a circle, eyes closed<br />Place both hands into the middle, grab hold of another (just one) hand. Make sure you've got a good grip.<br />Open eyes, anyone still with a free hand raises it and grabs another free hand.<br />Now untangle without letting go. <br /><br />This can be easy, or take a surprisingly long time, I did this once with about 100 people and it took over an hour to get untangled, but noone wanted to stop, I think because they wanted to succeed. <br /><br /><br />
