A summertime fidget spinner I can endorse

If you aren't plugged into Derek Muller's Veritasium YouTube channel, it's time to correct that oversight.

His latest exploration involves hydrodynamic levitation. It's a phenomenon very different from the Coanda effect-based airstream levitation. And it constitutes a summertime fidget spinner I can wholeheartedly endorse!

Muller is, of course, armed with high-speed videography. He recently added schlieren photography to his arsenal. I'm delighted to support him on Patreon; the guy does great stuff that's always fun to watch.
