Balancing Nails
Instructions
The performer should challenge the audience to balance all 6 10 nails on the head of the nail in the wood. The nails must balance without aid and must not be touching anything apart from the head of the nail in the wood.
Solution
To successfully balance all the nails on the head of one nail they must be arranged as follows: Lay one nail on the table on its side, then place 2 8 nails alternately at a right angle over the top, with the head of each nail resting just over the body of the nail underneath. Then place the last nail on top, sealing the nails at right angles in between. The weight of the top nail should stop the others from falling out. Gently lift the nails off the table and place them carefully on the head of the nail in the wood. They should balance perfectly.
