The Performer inflates a large round balloon and attaches it to the center of the tray. At his command the balloon pops and a live dove appears seemingly right out of the balloon! A perfect trick for an untrained dove because it can't fly away. The Crystal Box is also great for spring flowers or bills. The box itself is made of top quality materials including beautifully painted wood, brass fittings, and durable Plexiglas. The crystal box is also fully collapsible for easy storage and transportation. The Crystal Dove Casket is truly a great piece of highly functional, high quality magic
