Tricon Panel Production Plastic by Mr. Magic - Trick

Show a panel consisting of three parts. One side of the panel is red, while the other sides are blue. After showing the panel on both sides, it is formed into a triangular tube. Next, reach into the tube and produce colorful silks, one after another. Close the tube flat to show that there is nothing hidden inside. Once formed into the tube again, continue to produce even more silks.
