With the Slurpee Maker, you can enjoy Slurpees in your own hoe. Add your favorite pop or juice, and let the machine do the rest. The Slurpee Maker has an auto shutoff feature that will prevent it from spinning if the lid is not firmly in place. Simply press down firmly on the blue lid, then slide it forward toward the on switch until it snaps into place. Just add ice and a favorite soda or juice and slush into a frozen treat. Includes maker, small cup and spoon. All you need is a soft drink or juice, salt (to get it cold fast), and ice. The unit is battery operated, so it turns itself.
