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’m totally Schlieren right now. Amazing sights of sounds.

Friendly reminder that the doves in the Efteling (Netherlands) are either gray, white, pink blue or green.

They are tame birds and painted with animal friendly dye. They are painted 4 times per year. They used to bathe them in the paint, which didn’t actually harm the animals but made them drowsy for a few days, but later animal welfare decided they could only be painted with brushes. The German factory that sold the paint went bankrupt and the Efteling bought all of their remaining paint. 

The painted doves are less likely to be attacked by birds of prey, so this method is also used by pigeon fanciers. It’s animal friendly and looks very cute so I thought I would share.

Damn. I never saw any of them when I visited.
