I got curious about whips and came across this video from Smarter Every Day with guest April Choi. They took amazing slo-mo footage with Schlieren imaging of a whip cracking and breaking the speed of sound. You can see the shock wave forming around the tip of the whip. It's incredible. https://www.youtube.com/watch?v=AnaASTBn_K4 (the video has an ad for Audible near the end)

![Wide shot of idol of Hindu deity Krishna in green seated in the driver seat of a horse-drawn gilded chariot with a silver figure of Arjuna in the passenger seat. The chariot is drawn by four silver horses [screen left] and has an ornate roof with a small umbrella at its front. At the leading edge of the roof, behind the umbrella, sits Lord Hanuman holding up a gilded flag. A string of white flowers (some red roses) around Krishna. Arjuna sits with hands folded in a prayer pose. Two rails of oil lamps on either side of the chariot, and two tall traditional oil lamps on both sides of the chariot in the front. Dark blue cloth background behind the chariot.](https://files.mastodon.social/media_attachments/files/115/513/525/080/572/968/small/e512c99d6f13336d.jpg)
![Close up of an idol of Hindu deity Krishna in green seated in the driver seat of a horse-drawn gilded chariot with a silver figure of Arjuna in the passenger seat [screen right]. Just the two front pillars of the chariot housing are visible (and nothing else of the chariot itself). A string of white flowers (some red roses) around Krishna. Arjuna sits with hands folded in a prayer pose. Krishna wears gold palm coverings, a gold crown, and lots of gold ornaments.](https://files.mastodon.social/media_attachments/files/115/513/526/597/146/994/small/02ddd3590751291d.jpg)
