I think wintergreen lifesavers emit light when you crunch them.

Once upon a time, I was peeling a banana in a dim and very dry room, and I'm pretty sure I saw a spark, perhaps caused by the same phenomenon.

That's how you get girls to agree to turn off the lights when playing post office.

I swear this news popped up a few months ago as well.

> This discovery could have significant implications for the development of future technological devices
I whish science could stop having to make bullshit claims to get funding. This kind of research is cool because it explain the world we live in, it's doesn't have to be a pathway to technological devices to be legitimate.

It's cool also because ice.

I could envision significant energy production for this technology near glaciers or ice sheets with lots of melt activity. Admittedly not really a market, but worth exploring for future applications (eg on icy moons)

Draft grant proposal - power a giant van de graaf generator by dropping asteroids onto the artic ice cap.
Reminds me of x-ray getting generated when you peel off a duct tape or something.
