Featuring 8 modes with push button control (7 solid on colors and 1 color change mode), our 8 Mode Rainbow cubes are the most popular. 8 Mode Rainbow cubes allow you to add selective colors to any occasion. They are extremely popular with weddings and other special holidays or occasions. Rainbow cubes bring any drink to life with amazing colors! 8 Mode Rainbow cubes are completely safe to put into any type of cold beverage. They are encased in a waterproof non toxic shell and packed with freezable gel to keep your favorite beverage frosty. Our cubes are push button activated. Not liquid activated like the generics. Battery life is quoted at 24-36 hours so you can get several uses for multiple events. Simply hand wash and put away in a cool dry place until they are needed again. They can be placed in the freezer for extra cooling power so your drink is the hottest thing while staying cool. Our cubes will have your guests talking about your special event long after the regular ice cubes have melted!
