Ice Cream Mugz Personal-Size Instant Ice Cream/Slushy Maker, Penguin Personal-sized Mugz allow each child to make, then enjoy their OWN treat. Takes only about 3 minutes to turn ingredients into a smooth, tasty, fresh iced confection. No motor or batteries: the only energy required is a little vigorous shaking. Ingredient options are unlimited: juice, milk, cream, fruit, nuts, raisins, sugar, etc. Ice cubes & salt in the lower part of the cup "magically" freeze ingredients in the top.
