Coin in Ball of Wool Idea
By Herb Runge

Have the ball of wool, with the coin slide in it in a paper sack. The fake is sticking out of the sack on the side away from the audience.

When you steal the marked coin from your rattle box or from under a handkerchief, secretly insert it in the slide as you pick up the bag.

Reach in and remove the ball of wool with your right hand. Your left hand retains the slide in the sack by pressure on the sides.

All that remains is to have the wool unwound. The marked coin is inside.
