In partnership with Justin Sopher, SansMinds is proud to bring you TST. Or, Torn, Seal, Transform. The concept is devilishly simple and allows for a wide range of possible performance strategies. 

Notably, the gimmick allows for a mentalism routine to be spiced up with visual magic in a way that was not possible before TST. 

A torn corner is shown inside a plastic bag, its identity unknown. A card is chosen by the spectator and lost in the deck. The magician takes the bag, shows the corner inside it to be blank. The spectator names their card and with a flick, the corner transforms into a corner of their selected card inside the bag. 

When the spectator looks through the deck to find their card, they see it has a corner missing... and of course it matches perfectly with the one in the bag.
