Watch a DIY Youtuber capture slow-motion images of a Tesla coil
The 19th century technology is still used in cutting-edge aerospace engineering.
Invented by Germany physicist August Toepler in 1864 to study supersonic motion, Schlieren photography is a visual approach that captures the flow of fluids of varied densities. Today, it's commonly used in aeronautical engineering to picture the flow of air around objects.
This video by the Action Lab takes place in that peculiar region where a schlieren image meets a Tesla coil. A Tesla coil, in case you didn't know, is an electrical resonant transformer circuit invented by Nikola Tesla in 1891 which is used to generate high-voltage, low-current, high-frequency alternating current.
In this interesting video, the host of the YouTube channel James Orgill shows how you can set up a Schlieren image. Then, he images a Tesla coil, along with many other things. If you're curious to know more, be sure you watch the video embedded above, and as always, enjoy. Then, you can enjoy this video where the creator has attempted to answer what would happen if you flew a drone in an elevator.
