This is the Original Slush Mugg from 1983. You simply put the inner mug into the freezer and when it is frozen, add your soda, juice, or adult beverage mixture and it will slush it up! The amazing Slush Mug turns nearly any beverage into a Slushee in just a few minutes. Because the Slush Mug doesnt use ice or a blender, it doesnt water down your Slushee like other products. The Slush Mugs secret to creating Slushees with the perfect consistency is its patent-pending Glaciercore. Simply freeze the Glaciercore and then add any naturally sweetened beverage to create a Slushee in minutes.
