4 card surprise

Super Cute card trick.
The magician shows four cards face up. He puts the cards together and snaps his fingers. If he is fanning the cards one card turned over; it lies face down and one sees a red back.
He cut into his fingers and now there is suddenly a different card turned over.
This he repeats with all four cards.

Then suddenly all rugkleuren changed from red to blue.

But ... the spectator as against blowing upon the cards they have no red or blue back, but each card has a different color back!

Very visual trick, to do with some practice, pretty good.
You will receive the special bicycle cards (poker) and a dutch instructional video!
