Reporting in The Journal of Physical Chemistry B, researchers were surprised to find that different frequencies of sound produced different patterns in a color-changing liquid. Studying reactions like this could help scientists design chemical computers that can hear and process information.

Narrator: This liquid can “hear” different frequencies of sound. These psychedelic swirls are made by vibrating a special chemical mixture that reacts to the motion with oscillating color changes, kind of like how our ears sense sound and produce pulses of nerve signals.
The researchers were surprised to find that different frequencies made different patterns in the liquid. [high vibration tone] [low vibration tone]
Scientists hope studying reactions like this could help them design chemical computers that can hear and process information. [vibration tone]
