The magic of how to put playing cards into mineral water bottles is a very popular magic show. This trick requires an empty bottle and a deck of playing cards. First, the magician will show the empty bottle and ask the audience to check its integrity. Then, the magician asked the audience to choose a playing card and sign it. Next, the magician put the playing cards back into the pile and inserted the whole pile into the mineral water bottle. Finally, the magician knocked on the bottle and magically took the signed playing cards out of the bottle.

The key to this magic trick is how to get the whole stack of cards through the bottle mouth. The magician needs to prepare a pile of special cards, one of which is cut open and stuck with other cards to form a pocket. When magicians insert the whole stack of cards into the bottle mouth, they can put the cut cards into the bottle and then put other cards through the bottle mouth from their pockets.

In addition, the magician also needs some skills and performance skills to make the magic more realistic. For example, they can shake the bottle and let the audience see the cards in the bottle moving, thus covering up the essence of magic. The magician can also put the bottle at a special angle so that the audience can't see what is in the bottle.

Generally speaking, the magic of putting playing cards into mineral water bottles requires the magician's superb skills and performance ability, as well as some special preparations. Although the essence of this kind of magic is deception, the audience is still attracted by its magical effect.
