Mesmerizing Time-Lapse of a Chemical Reaction Rippling Through a Petri Dish
The intersection of art and science can be a beautiful place, a point that’s made very clear by the online video project Envisioning Chemistry. In their latest creation, you can watch a chemical reaction ripple through a petri dish, a beautiful example of an “oscillation reaction.”
Envisioning Chemistry is a collaboration between the Beauty of Science and the Chinese Chemical Society that seeks to “reveal the beauty of chemistry through special techniques such as macro and micro photography, high-speed photography, time-lapse photography, and infrared thermal imaging.” We’ve featured their videos in the past–including time-lapses, macro, and slow-motion work–but there’s something especially hypnotic about their latest release.
What you’re looking at is a time-lapse of a Belousov–Zhabotinsky (BZ) reaction, which is a classic example of a “nonlinear chemical oscillator.” The reaction–which doesn’t actually move too much slower than this in real life–shows non-equilibrium thermodynamics in action, which is really interesting for scientists… and just plain “pretty” for the rest of us:
