The healing effects always surprise the audience in any situation. So do HEAL, a new product comes from Smagic. 
You let the spectator pick a random card or you could borrow a dollar bill from him. And then you tear the card but dont detach them. 
Needs only a snap, everything comes back from the beginning.
This trick is really visually special because the spectator can check and control carefully the whole performance.
Its really convincible and you must have HEAL in your collection
