National Juice Slush Day is celebrated annually on the third Wednesday in May, with this year's observance taking place on May 20. The day commemorates the enjoyment of juice slush, a refreshing beverage that has roots dating back to the practice of adding fruit juice to freshly collected snow. Historically, royal courts would use recently fallen snow topped with crushed berries and mashed fruits. In modern times, juice slush has gained popularity, especially among children during lunch breaks, and is often marketed by brands like Cool Tropics and Welch’s. The drink is made with real fruit juice and is free from artificial colorants, making it a healthier option. Cool Tropics initially focused on frozen slush equipment but shifted to creating convenient 100 percent juice slush pouches in 2008, targeting K-12 students for various occasions.
