The magician shows the audience a flat pyramid. One side is yellow and the other is red. The magician folds up the panels to create a yellow pyramid, and then produces several yellow silks, one by one. The pyramid is opened, and re-folded creating a red pyramid. Now, several red silks are produced. Surprisingly, the last silk is blue, so the pyramid is unfolded and the inside color has changed to blue! The pyramid folds into a small flat triangle for easy transport, and will even mystify magicians! Silks not included. Very high quality, imported from Europe. $97.
