Have fun making frozen treats with the ZOKU Original Slush and Shake Maker! Whip up slushies, milkshakes, frozen cocktails, and fruit smoothies in as little as 7 minutes. Great for both kids and adults, this cool slushy cup is perfect for parties. Try using fresh fruit smoothies, homemade juices, chocolate milk, flavored sweetened coffee, sodas, floats, and other cool stuff. Freeze the inner cup for 8+ hours, pour in your cold drink, and use the spoon provided to scrape the cup every 1 to 2 minutes. Remember, the drink needs to include sugar to work properly; sugar-free and diet drinks do not work. This slushie cup holds 8 fluid ounces and stands approximately 6.5 inches tall.
