Guess Which!

From your pocket, you take four  coins and four small pill boxes. Which your back is turned, the audience cover the coins with the boxes and move them round.  When you turn round, you can at once tell which coin is under which box and which way up it is – without lifting the boxes.
	The coins are two pennies and two dimes; one of each has short fine hair glued to it.  The prepared coins are laid down with the “Tails” side up. The other coins have their “Heads” side up.
NOTE:  You only need move two boxes to name all coins – a box showing a hair and one that has no hair.
When the coins are covered, look for the hair (A & C boxes in the above sketch).  Move one box forward.  If it rattles, it contains the dime, which is not as tight a fit as the penny7. If it has a hair showing, it’s a “tail”, yet if no hair, a “head”.
So you can name the coin under any box indicated by the audience, or all the boxes, if you prefer.
