Jumping Gems – One black plastic rod has one diamond gem on one side and a ruby gem on the opposite end of the other side. The second rod has two diamond gems close together on one end of one side and one diamond gem on each end of the other side. In this effect, first, both rods appear to have no gems. One diamond gem appears, now it's on both sides of the rod. The diamond jumps to the other rod. Now it's on both sides of that rod. Next there's a diamond on each end of the rod. Then one diamond is pushed up to join the other diamond. Now we lose a diamond, or did it jump to the other rod? Last, it's obvious to the spectator that the lone diamond is under your thumb. Lift your thumb, surprise, it's a ruby!
