Color Changing Doll House by Mr. Magic

Color Changing Doll House by Mr. Magic 

The performer displays a square tube with yellow borders. He lifts and tilts it to show the tube totally empty. He replaces the tube on the table, utters some magical phrases and lifts the tube. A yellow doll house is produced from inside the tube. He once again shows the tube empty and places the tube beside the doll house. When the tube is lifted, a blue doll house is produced. Amazingly, the magician produces another doll house of red color from inside the empty tube.
