The Fascinating Photographic Process That Makes Changes In the Air Visible to the Naked Eye

In a fascinating episode of Veritasium, host Derek Muller explains the science behind Schlieren imaging, the specific process by which those things that are normally invisible to the naked eye reveal themselves to be present.

This is what the world would look like if you could see invisible air currents, temperature gradients, and differences in pressure or composition of the air.
