Everyone who has played poker or even Go Fish knows the basics of shuffling cards. There's the riffle shuffle (combining two halves of a decks and making a bridge), overhand shuffling (quickly splicing cards from the deck back into the deck) and regular ol' mixing all the cards up on a table. Which way is the best?
I don't know how many finger exercises it takes to pull this off or how much wizard potion these kids from Singapore drank but they make shuffling cards look like a dancing symphony. Each finger seems to be powered by its own brain and yet they all work in concert to make complicated movements look graceful.
