Some physics? Sure, why not.
Here’s Wired on doing some acoustical science to figure out an impossible Beatles chord on “Hard Day’s Night”.
Here’s Swans on Tea on the free energy claim that’s been circulating of late. I’m going to write about this eventually if I get around to it, or maybe I’ll just wait to write the post until they have a working model. In that case you may be waiting for quite some time…
Here’s a cute physics puzzle from Dirac Sea: given a candle put in a centrifuge, which way will the flame lean? Easy if you’re familiar with a few concepts, but I’d best most people wouldn’t know.
Finally, I think this is kind of old but it’s neat nonetheless. A table saw that uses some snazzy electronics to instantly detect and stop itself from chopping off fingers:
