In the movie Frankenstein, I remember seeing tubes in the laboratory.
Besides the monster being scary looking, the tubes and electricity in
the laboratory was also very scary.

There was also two large electric bolts. I think that was real because
I had seen things like that in Edison's photos.

I wonder if these tubes were real or made up to make the movie even
more
scary? Also, taking consideration the times: It would be normal to see
electric tubes in a lab.

I wonder if you're referring to Tesla coils.

Probably a Jacob's ladder. I made one of these once using a big neon
sign transformer. The sixteen thousand volts would jump a half inch gab
at the bottom of the rabbit ear shape electrodes and then move up the
diverging wires because of hot air.

Ah, I'll bet you're right.
