Whether you’re organizing a party, event, or using them for everyday amusement, Glo Drinks are professional entertainers. Made from food-safe, BPA-free plastic, they smoothly cycle through 9 different colors for up to eight hours, without any switches, knobs, or buttons.

Glo Drinks started off as a college project. Mississippi Makers Hagan & Kylie, wanted to create a tea that would glow, and invented a way to keep a light on under water.

We’re happy they did. Now, you can liven up a party with just liquid and this.
