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.

Ever wonder what a snalrus sounds like? (That’s a snail and a walrus…) What about a Deagle? (Dog and Eagle) Well now is your chance to find out! Name and sound design your own hybrid animal, then submit it to the Hybrid Animal Sound Design Competition. The competition features $6,000 in prizes from Pro Sound Effects, Avid, iZotope, Rode, and Ric Viers!
