MATCH BOX TRICK

THE FIRST OF MY MATCHBOX USES.!!! HAVE 3 BOXES ONE 3/4 FULL OF MATCHES A ND THE  OTHER 2 EMPTY? A RUBBER BAND.? THE 3/4 FULL BOX ATTACH TO YOUR WRIST LEFT HAND WITH RUBBER BAND? AND HIDE UNDER YOUR SLEEVE?? THE OTHER 2 LAY ON DESK IN FRONT OF YOU.? ASK A SPECTATOR TO CHOOSE OR POINT TO A BOX? THE ONE HE POINTED TO PICK UP WITH YOUR RIGHT HAND AND SAY ITS EMPTY BY SHAKING IT? YOU PICK UP THE OTHER BOX IN YOUR LEFT HAND AND SHAKE IT? IT RATTLES? WRONG CHOICE?? MOVE BOXES AROUND THEN ASK TO SPECTATOR TO PICK ANOTHER BOX.THE SAME AGAIN HE WILL ALWAYS PICK WRONG BOX ? REMEMBER ALWAYS PICK UP THE BOX WITH LEFT HAND TO RATTLE IT?THIS IS EASY TO DO JUST GETTING THE TIMING RIGHT? AND YOU WILL BAFFLE A FEW PEOPLE OLD OR YOUNG?  SEE NEXT TIME WHAT YOU CAN DO WITH EMPTY BOXES OF MATCHES.?THIS IS JUST ONE SIMPLE TRICK.?!! REMEMBER YOUR THE ONE THAT CAN MAKE THE EMPTY BOX RATTLE.EASY NOW YOU KNOW??
