1. Have your friend hold two of the rocks together as hard as possible while you perform the trick.
2. Now take the extra rock, and wave it around your friend's rocks 8 times.
3. Then use the same rock to touch each of your friend's knuckles on both hands.
4. Now tell your friend to very slowly try to pull the 2 rocks apart. It will feel like they are tied together!
