Colour Changing Card Trick
Great video showing how people perceive and recognize change in colours. This card trick takes a deck of cards with a blue patterned back. The cards are placed on the playing table face down. The assistant selects a single card and shows the audience the value. The card is placed back into the deck of cards and the cards are spread across the table a second time. This time the back of all of the cards are now red. Except for the one card that was selected by the assistant, it remains blue.
The trick isn’t all that complex, but something else unexpected happens… watch the following video carefully, see if you can figure it out before they provide an explanation at the end. Very well done trick!
