If you’re looking for a fun way to beat the heat, fizzy fruit is the ultimate summer snack. Fruit gets carbonated when you pack it with dry ice, so you end up with fruit that literally tingles on your tongue—no added sugar or soda required! It’s a fun science-meets-snack project that’s perfect for summer parties, kid-friendly experiments, or just cooling off on a hot day. —Hetal Vasavada, San Francisco, California
