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.
