Instructions
1. Take your piece of string and tie a loop in each end so that your hand can fit easily through the loop, with room to spare.
2. Put your left hand through one of the loops.
3. Link your string with your partner's string, and place your right hand through the remaining loop as illustrated.

Challenge: You and your partner should now be joined by your strings. The challenge in this puzzle is to detach yourself from your partner without cutting either string or removing your hands from the loops at any time.

Good luck!
