Why Mosquitoes Bite Some People More Than Others

$How To See Air Currents 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. Support Veritasium on Patreon: http://ve42.co/patreon Special thanks to Patreon Supporters: Tony Fadell, Donal Botkin, Jeff Straathof, Zach Mueller, Ron Neal, Nathan Hansen I first saw a Schlieren imaging setup around ten years ago in Melbourne. I was immediately fascinated by the way I could see the warm air coming off my hand. I hadnt expected the currents to be moving that fast or to be so visible. This was a tricky setup to get right because alignment is very important and here Im just working with what I had lying around the house mostly (plus the mirror). For the best Schlieren photography, making sure the mirror is stable is essential. I want to improve my setup so the mirror doesnt wobble back and forth too much creating the pulsing light and dark sections of this video. The relationship between index of refraction of air and temperature, pressure, humidity and wavelength is complicated.
