The latest revelation is that one can weigh an aeroplane flying overhead from the ground.
At least, that is what a YouTuber called Brian Haidet – a materials science PhD – has demonstrated in a video on his excellent AlphaPhoenix YouTube channel.
En-route, he built a set of scales about 2m long and 1m wide that can weight within a gramme or so.
Very impressive, and well worth a look.

I watched this video too! He does such great and extensive work to explain science to viewers! To his credit, he also explains the shortcomings in his test set-up. I noticed that in the video description, he does say that a proper pressure sensor would be a better way to measure the change in air pressure, but a good one costs too much. He’s one of the best general science YT folks, imho, etc.
Some years ago I was chatting to the inventor of the vibrating beam load cell (used in some of the Avery FX series scales, like you see in the Post Office). At one point we drifted off into the possibility of using the load cell to weigh the moon, although it never got past casual conversation. It is capable of a lot more than it was ever used for in commercial and industrial products.
