Yep, i know what i am talking about because someone made a simmilar post in a different forum but he only got replies about clutching on the back of the hand and i can do this but i have seen a vidio on newmagicsecrets which is a pro site with difficult ones and it is done so smoothly that you cannot believe your eyes.
Except on this particular one he actually uses a dice as it makes it look more... ~magic~

to see what i am talking about.
edit* Oh yes, by the way, if you watch this so carefully that when he opens his hand you can see the die between his Thumb and Index finger. - You are wrong, that is not the die, that is the red book on the bookcase in the background. lol
