Father and child take a piece of string about four feet long. Tie the ends together. Put the string over your thumbs, in front of your palms, and over your little fingers. Turn palms toward each other. Stick the right middle finger up and under the loop which is across the left-hand palm. Ask someone to put his hand up through the middle of the string formation. It looks as if his hand is in the middle of a loop of string. Release the string from all your fingers, but not from your thumbs it is not around the person's hand at all.
