You show a regular dice in your hands and then squash it. Magically it flattens! You are supplied with a dice which is attached to a retractable reel.
To begin the trick make sure the flat dice is in one of your hands and then dice is expanded to sit amongst your fingers in the palm of your hand. You will need to pin the dice onto the back of your pants.
It's as simple as bringing both of your hands together and as you do you let go of the normal dice and it will fly back underneath your hand to the back of your body where you have pinned the reel.
You will of course open your hands to reveal that the magic has happened and the dice is now flat!
Practice makes perfect! Check out the below video...
