Did you know that the theory behind neon sign technology dates back to 1675 before the age of electricity, when French astronomer Jean Picard noticed a faint glow in a mercury barometer tube. When the tube was shaken a glow called barometric light occurred. The cause of barometric light was not understood, but it was investigated. Later, when the principles of electricity were discovered, scientists were able to move forward towards the invention of many forms of lighting.

Lovely light in the photo! Today is the shortest day - so now it's turning and the days will start getting shorter! Hurray!
This was so interesting and I loved your play on words with the title of this outstanding photo.
I wonder why the choux pastry delicious morsel is called an eclair - maybe because of its lightness?
*sigh* You have such a lovely way with words you know!! (and your pretty good with a camera too!!)
