I can understand this reasonably well, but I figured even those who can't might enjoy it. It shows 1940s GE fluorescents being made.

very nice and well made, unless the "poor" mercury atom annoyed by electrons

I can't understand what they say, but i understand. Also because it's nice explain with the funny drawings of the atoms and the ladies in a dress in the factory
Nice video, good found!

Thank you!

No problem!...looks to have been uploaded only a few weeks ago. I just happened to see it when surfing around after watching the Spanish one.

This is my favorite video. It's so well made and makes me feeling to be back in the 40s.

That's a nice video! And it is quite mind blowing that the fluorescence effect was discovered over 400 years ago.
