This activity is good for dividing the group into pairs. The facilitator takes a number of threads equal to half group size (e.g. 5 threads for 10 people). He holds all threads in his fist so that the participants only see the ends of the threads and don't see which end belongs to which thread. The facilitator then asks each participant to take one end of the thread. After everybody did so, he uncleanches the fist and each pair is connected by a single thread.
