The color rotation is surprisingly smooth and adds a fun, dynamic glow to my cocktails. I've used them in water and soda water, and they work instantly every time. Makes serving drinks at parties much more entertaining.

Dropped these in my daughter’s punch bowl at her party and the rotating colors were a total hit—they stayed bright for hours. The cubes themselves are a nice size too, not too bulky for a standard glass.

The cubes lit up nicely in my glass of soda water, and the color shift was fun to watch. They are a bit dimmer than I hoped in a full glass of dark cola, but still a neat party trick.
