The truly amazing Aussie Ice Slushy Maker uses a simple saline solution and science to turn virtually any drink into a fun slushy. Simply freeze your Aussie Ice Slushy Maker in the freezer for 3 hours, and then add your favorite drink - it can be anything as long as it's been refrigerated. Add your drink to the silicone cup and massage gently for 1 to 2 minutes, or until you reach your desired slush texture. In between the double walls of the slushy maker is a thin solution of salt water, which freezes at a lower temperature. The Aussie Ice Slushy Maker transfers cold from inside the cup to make slush as opposed to diluting it with crushed ice from a blender.
