Did you know that mixing the card pack in "faro shuffle" (the cool way to mix cards - as in the picture) does not mix the cards at all?
If I tell you that, I'll lie to you.
However, if you mix a standard card deck (52 cards) in this method 8 times in a sequence perfectly, the package returns to its original order.
Bonus works: "Faro shuffle" is the American name of the mixture and its British name is "weave shuffle".
