On the table are two glasses (real glass), one containing yellow and the other one containing a red silk. The magician takes the yellow silk out of the glass and covers the other glass with the red silk. Now he takes four playing cards (the aces) and shows them front and back. The cards suddenly and visibly change into a red silk, the yellow silk is now removed from the glass and the four aces are in that glass!
Comes complete with glasses, silks and cards. The glasses and silks can be examined and be shown around at any moment. These are all NOT PREPARED. No mirror-glasses….of course instructions are included.
