What was a bit weird about Hong Kong neon signs (nearly all gone now) was that they were static. No flashing, no animations. This was because the old airport at Kai Tak had an approach path low over city streets and rooftops. Flashing neon signage would have distracted pilots' perception of the approach guidance lighting.
Geissler tubes feature prominently in my book The Three Locks, a Sherlock Holmes Adventure published by HarperCollins. As a celebration, my scientist husband gave me a Geissler tube for my birthday that it up red. Fabulous!
This is absolutely excellent. I can’t believe how much I learned from this piece that I knew nothing about, thank you so much!
Thank you!

Wait you can *buy* a Geissler tube in the 21st century?
Once again, very enlightening đŸ’¡
It is also a reminder that everybody can contribute to the advancement of technology, even if they did not study in science or engineering.
