Inspire frosty fun in the kitchen all year 'round with this family-friendly gift set. Zoku's innovative cup makes slushies or milkshakes in minutes, right on the countertop. Just place the inner core in the freezer for at least 8 hours, then pour in your liquid and stir—the beverage freezes right before your eyes. When it comes to cool options, possibilities include everything from fruit smoothies, slushy chocolate milk and root beer floats to iced coffee drinks and cocktails. For inspiration, we've included Zoku's own Art of Slush book.
