Magnetic Fingers Trick
This trick appears to be like hypnotism. Is your patter good enough to convince them ?
Ask your friend if you could try a little "instant hypnosis" on them.
Assure them that it's safe and nothing harmful can or will happen.
Next, ask your friend to fold their hands together, weaving the fingers and clasping them tightly.
After a few moments of doing this, tell them to raise their two index (first) fingers so they are sticking up and they should be about an inch apart ("church and steeple" kind of thing). Now, slowly move your hands over their hands (don't touch their hands) and say, "Your fingers will touch. Try to fight it, but they will still touch!"
Slowly, but inevitably, your friends fingers will start to move together. Tell them to concentrate on their fingers (just use some patter to create some atmosphere.) and soon their fingers will touch.
