Various cards with images of drinks are shown. The spectator chooses one, then the magician takes from an envelope a giant pad of paper, saying that he will guess which drink the spectator selected. The magician draws a can with its corresponding logo coinciding with the one chosen by the viewer!
Subsequently the sheet is torn off and an actual can is made to appear!
This effect can also be performed by making bottles or a cup appear instead.
Very easy to do!
