I think it’s safe to say that we are the hydration generation. We’re carrying around drinking tumblers or water bottles with allotted times to drink and encouragements to keep going. We’re mixing our drinks with electrolytes and flavors or anything else we learned on WaterTok. And we’re utterly fixated on ice cube molds. Not just the regular square ice, but shapes like stars and hearts and tiny fruits. While it is fun to freeze our ice into the shape of little strawberries, that’s a lot of ice needed for your 40-ounce Stanley cup or one of the dupes! Thankfully there’s a solution out there; a one-and-done ice cube mold that fits perfectly inside your Stanley. And, of course, the internet is obsessed with it.

This ice cube tray is made of BPA-free silicone, making it easy to freeze your ice and pop out the molds when it’s time to fill your cup. The mold has three hollow cylinder spots, all with different shapes: 2.4-inches in diameter, 2.8-inches in diameter, and 3.3 inches in diameter. Why the different shapes? That’s because these three cubes will perfectly fit in your Stanley cup. The smaller first ice mold goes in first to fit the thinner section at the bottom, followed by the second and then the last. Each cube sits 2.8 inches tall, making sure all of the ice cubes perfectly fit standing on top of one another in your cup.

The hollow cylinder design is meant to give you more room for your drink. Some clever TikTok users fill up their molds with slices of lemon, orange, or lime to create a fruit-infused water. When the mold is full, it is then placed in a sturdy plastic container so your mold doesn’t flop over when you try placing it in the fridge. This ice cube tray retails at $19.99 on Amazon. It comes in three colors: sage green, brown, and yellow.

Although these cubes perfectly fit in your Stanley cup, they also work well for other drinks. Want to serve whiskey on the rocks? (Well, in this case, on a single rock.) Want to get creative with your margaritas? These ice molds work well for your cocktail nights, or perhaps one of these other great uses for ice cube trays as well.
