A truly cross-era work that can be put into practice - Supernatural Ink
The magician lets the audience choose a card (such as the 2 of Spades) at random, and after randomly shuffling the cards, the magician tries to find the audience's card, but this is a brand new form.
The magician takes out a pen and draws some wavy patterns on the back of a card, and even lets the audience touch it. The magician shakes the card with the pattern, and the ink on it begins to move as if possessed by a soul! !
Finally, the ink aggregates into a 2 of Spades! That is exactly the card chosen by the audience!
The whole process can be performed at close range. The exquisite design of this prop is completely worthy of scrutiny. The prop has no concave and convex layering, no FLAP structure, no creases or other easily discovered doors. It is a supernatural ink that can be performed at close range! !
