Magic effect
The spectators can call a stop at any time in the magic card picking, and the spectators can sign the selected cards to ensure that they are not stolen and that there is no second identical card!
Then the spectator puts away the cards and does not do any card control tricks!
Then the magician took out a pen and drew a heart on the back of the top card, and next...
The magician shook the card, and the hearts painted on it disappeared little by little! The audience witnessed with their own eyes the whole process of the disappearance of love
Opening the whole card again, I found that there was a heart painted on the back of one card. The missing heart found the spectator's card!
The card with the heart at the end can give the audience a memory, a perfect magic trick!
