- The hotter the temperature, the better the effect.

The colder the temperature, the better the effect. An ice cold beverage is most ideal. Adding ice cubes can also enhance the color changing effect. Cold liquid needs to be a maximum temperature of 10°C/50°F (cold tap water) in order for glass to change colors Recommended temperature is around freezing level -6.67°C/20°F (ice cold water) for optimal color changing
