The Aussie Ice Slushy Maker is great for the whole family. Kids can make slushies from juices, sodas and even chocolate milk. Adults can make their favorite drinks, including margaritas, energy drinks and diet sodas into tasty slushy treats, too. The patented design uses double-walled construction of food-grade silicone for the cup. Sealed between the inner and outer walls of the cup is a saltwater solution that freezes at a very low temperature. When you pour your drink into the cup, it gets supercooled into a frosty treat without using ice or a blender. Place 8-10 ounces of your favorite beverage in the Aussie Ice Slushy Beverage Maker and chill in the refrigerator or freezer. You will have a slushy drink ready to go with a straw spoon. Pull out the bottom to easily slurp up the last of your tasty slushy. The lid and spoon straw are top-rack dishwasher safe. The cup is hand-wash only. The neoprene sleeve can be machine washed and dried.
