Kind of crazy, but also a pretty fun idea. Brought to you from Brazil, where Alexandra Bark and Gustavo Vieri have come up with a way to use a syringe in combination with card magic!
You pull back the plunger so everyone can see that the syringe is empty. The next moment you can "suck" a playing card out of the air, the deck, the close-up mat - or perhaps the arm of the spectator. You can then take the syringe apart and find the spectator's chosen card (or just thought of) rolled up inside the syringe!
A completely unexpected, original and rather sensational element - just to blend into your card routines.
