A deck of cards is introduced and a card is selected and signed across it's face. This is then replaced back into the deck and the deck is shuffled by the spectator. The magician then takes two rubber bands from his pocket and asks the spectator to wrap them around the deck so he can do anything sneaky with misdirection. The magician then shows the glass bottle around on all sides and removes any large labels so you can see right through the bottle. Then the rubber bands are given back to the magician and the spectator holds the deck ready to throw it at the bottle. The magician holds the bottle with one hand on top of the bottle and one hand at the bottom. The spectator then throws the cards at the bottle and the magician 'catches' one of the cards IN THE BOTTLE! Inside the bottle the signed selection is immediately seen swirling around, the bottle still being sealed, of course!
Glastion really is that visual! This has to be the most amazing way to perform this effect, just how Nefesch's brain managed to spew this out for us all to enjoy is a mystery in itself!
