[Seeing the Invisible: Schlieren Imaging in SLOW MOTION] (Viewer #828,417)

The pacing is horrible on this one. He’s overestimated how engaging the images are, and lingers on them far longer than necessary. It’s like the “Star Trek: The Motion Picture” of informational videos.

Nevertheless, parts of it were quite interesting, and I survived the 6 minutes without jumping ahead. Just try to relax and enjoy the pretty pictures
