I have visions of it glowing, or even better having a spark bridge the gap and move, Frankenstein like, up and down between the crystals.
I am going to do some more research on the microscope thingey. And I will be replacing the cord early next week. Then the SPARKS will fly, but hopefully only between the crystals.
PS - While I was posting this blog Terry left me a note on the previous posting identifying the item as a colorimeter. It was used to compare the concentration of chemicals in solution. I did a little looking and determined that it is a Duboscq Colorimeter, made by Bausch & Lomb in the 1930's-40's. The crystals will glow the color of the solutions that the light passes through when placed between the light source and the crystals. BUT no sparks!!!
