skunkbear:

A couple months ago I shared some GIFs of invisible things, and I finally got around to putting them together in this video:

When light travels through areas of different air density, it bends. You’ve probably noticed the way distant pavement seems to shimmer on a hot day, or the way stars appear to twinkle. You’re seeing light that has been distorted as it passes through varying air densities, which are in turn created by varying temperatures and pressures.

Schlieren Flow Visualization can be used to visually capture these changes in density: the rising heat from a candle, the turbulence around an airplane wing, the plume of a sneeze … even sound.  Special thanks to Mike Hargather, a professor of mechanical engineering at New Mexico Tech, who kindly provided a lot of these videos.

I swear, hanging out with little kids is one of the best parts of my job even though I don’t get to see awesome little buggers like this one all the time. Nicholas is an awesome little dude. He was showing me where the Easter Bunny was working (taking pictures with kids).  (at Stafford Crossing Community Church)
