At first, everything happens like in the classic folded card trick.
The magician shows two cards and folds them.
He places one card inside the other and a miracle happens: half of the card is face down and the other half is face up... But that's not all!
Suddenly, the back of the face-down card changes color...
The spectator sees half the card red and half the card blue... But it's not over yet...
Suddenly, the whole card turns blue and then red again.
Both cards can be inspected by the spectator before and after the trick.
The trick is easy to do and, more importantly, doesn't require wires...
This is a modified version of the folded card trick with an advanced locking mechanism that Mario Tarasini launched a few years ago.
So get ready for a modern version of an old trick...
