You've seen coffee ice cubes, chai ice cubes, and melon ice cubes, but what about watermelon ice cubes? These one-ingredient ice cubes couldn't be easier to make, and look so refreshing. Put a couple in your cold seltzer water this summer and get a sweet treat as they slowly melt.

I don't know why I haven't seen this before, because the recipe is just so easy and obvious. All you really need is a big, fresh watermelon and a delicious beverage, like sparkling water or lemon-lime soda. It's definitely what I'll be sipping on all summer.
