Three pearls on two pieces of string are shown. Get two spectators to hold either ends of the strings. Watch carefully! Tie a knot with the strings on top of the pearls and give the ends back to the spectators. So far so good! Ask them to hold on to the ends tight and not to let them go! With your left hand cover the pearls for a second. When you open your hand the pearls are FREE of the strings! The spectators are still holding the strings.
