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.

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 hadn’t 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 I’m 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 doesn’t 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. This website will calculate it for you:

that's a mouthful, can I call it a tiger
Does anyone know where I can find a large concave mirror like the one in the video?? It will be helpful thxs !
Thats scary
Awesome! But be careful with telescope mirrors guys, they are beautiful and dangerous. Keep it away from the sun!!
@veritasium I accidentally found one in my laundry room! Check my channel, I don't want to link here for spam's sake.
Bro… ? This is insane, I LOVE it.

Wouldn't "parabolic" imply it's NOT spherical/a cross-section of a sphere?
Please, I have seen tries, buy my dream was to see all the different electromagnetic fields around us. Wifi, 3g, Radio, FM, VHF, so on. This one is hard.
Wonderfull,, Thanks
Interesting how the lighter lighting up created a small mushroom cloud.
Brilliant!
Hi
Veritasium
@5.48, May I use this frame as a cover art for my album? credits to you and advertisement on my album and songs is what I can offer.
Thanks let me know.
This guy is annoying and his face is dumb
Change my mind
Flammable bubbles would look really cool
Hey! Super interesting. Would love to see sound waves schliered 🙂
bring paranormal and expose a ghost
Have you tried or have you knowledge about use of the Schlieren Imaging principle in the SWIR band (0.9 to 1.7microns)?
Can this trap paranormal activities…Try it out
Discovered in 1665……. Whaaaa? So i guess it's plausible german scientists actually made ufo's back in wwII.
it's cool I liked it
Good evening sir! Would this still work if we use a camera module with a resolution of 640 x 480 vga?
What focal length lens did you use
A bicycle driving by.
Where can we get such mirror? Thank youuu
it also produces these awesome low rumbling sounds,, especially when popping a bubble ..
A rotating object movings through something dense like oxygen.. or even tungsten hexafluoride! It would be interesting to visualize the Magnus effect..
I would love to see air flowing over a streamlined rc plane Vs a not so streamlined plane
does schlieren imaging use the same setup as a foucault tester???
If you wonder why you get a spike of views on this video, it's this: https://www.nasa.gov/centers/armstrong/features/supersonic-shockwave-interaction.html
We are doing schlieren for shock waves visualisation . It would be helpful if u can share the camera settings
CAN IT DETECT A HIGH PRESSURE AIR IN A BALLOON PASSING BETWEEN THE CAMERA AND THE MIRROR IN TOTAL DARKNESS?
Can you show the vapors from a mercury amalgam filling when agitated ?
