A Tricky String Puzzle
Take a piece of string about a yard long and tie the ends together, making a loop. Passing this loop through the ring of a key, hang it upon the extended thumbs of a friend, as in [Fig. 27]. The strings are crossed. The trick is to remove the key without taking the string from the other person’s thumbs.
