I just remembered an example of triboluminescence I encountered when going to bed in a Motel 6 somewhere last winter. I was lying under the covers, my eyes were accustomed to the dark, and I noticed that when I pulled the blanket away from the sheet, I could see faint flashes of light between the two.

Anyone else have any memorable examples?

That bit of static discharge is fairly common in dry Winter conditions. I noticed it more as a kid partly from having a fluorescent light for a reading lamp and it would flicker, and partly from the fuzzy full-body (well, except for the head, of course) kiddie pajamas that were great at building up a static charge.

Yeah, I wore such pajamas to a sleepover once, to the amusement of all the other kids. They could see every move I made after lights out.

That was static electricity, rather than triboluminescence.

I did have to deal with triboluminescence once in a place where I *really* didn't want it... a darkroom! Years ago when I processing film in college, I was taking 35mm film out of the cartridge to put it on a reel for processing. When I got to the end of the film that's attached to the spool, I found (well, felt!) that it was taped, so I peeled the tape off the film. Much to my surprise I saw a brief, faint spark of light as I removed the sticky tape. Fortunately the light didn't ruin the film, but from then on I always cut the film rather than remove the tape, just to be certain.

It's triboluminescence caused by static electricity.

And whoops! Good thing the flash wasn't bright enough to ruin the film. Did it make a small splotch at the end of the roll where there were no pictures?

Y'know, I don't remember if it caused a small splotch. I was developing film for the college paper, so the only thing that mattered was "is it good enough to print (on low-quality newsprint)?" Anything more, didn't matter!

Now if it were my own pictures, that would be another story...

Hey by the way are you still shooting film with the manual Olympus? I remember it made for some funny frames in your cartoon diaries! "oops, me shutter's stucko!!"

Nope, that was Jay's camera, which I was borrowing, and I gave it back to him. I've gone digital now.

You blinded me with science!

Well, the wiki link was no help, I couldn't make much sense of what it is (but science-y things do that to me.)

But I think I've seen what you've seen, I have to go to work at an early hour - work starts at 6, and I'm usually getting dressed round about 530. Since I'm up before everyone else, I have to do so in the dark, and sometimes, when I take my clothes off the hangers (which are usually very close to other clothes, we have a small closet), there are blue sparks that appear! It doesn't even have to be a sweater or winter either!

The color of the sparks intrigues me most. Could your clothes be enchanted by Ulyaoth?

Sparks in the dark

That happens every night with my staticcey blanket. What is harder to reproduce is the phenomenon of your mouth making sparks when you chew that minty candy. My friend Joel says that it makes sparks, but I've never seen it.

I've never tried it, so I can't say.
