Total internal reflection where the water has a higher index of refraction than the air. Such as when you look into water and the light bends, from the water side, the slight angle cannot exit.
In fairness, the headline "confined to path" begets that you can see red because the light is not being wholly contained.
Water stream acts as an optic fiber. Laser bounces off the surface of the water so it stays inside the stream. Optic fibers used in communication use the same principle, except with a solid material instead of water.
I'm not sure. I suppose it could be scattering due to impurities in the water. TIR depends on the light hitting the boundaries at small angles. Photons scattered by impurities could be directed towards the sides at higher angles. The glass in optical cables is exceptionally pure. And the fibers are very thin which forces the angles to be small. The water stream is massive by comparison so probably not ideal.

The scientific name for this phenomenon is "hematuria".

Just as red as urine, interesting.

So what are you going to do with that bucket of lazers?

How old is this setup? I haven’t seen a pop bottle like that with the black base and the flange at the top since the 80’s.

That's rad!

↑ A peek in the bucket would have been cool.

When I pee, Doc, it's just blood. All blood.

Ah, It glows when I pee

As long as it's not red.

If you leave it running in the background with sound on while you're in another tab it sounds like a guy taking a really long pee.

Wow, that bucket is getting full of laser!

There’s SO MUCH laser in that bucket, I want some!

anything special about the water or is it just H²O

Just water.

Same principle as fiber optics, total internal reflection

You can test this at home, if you stuck a laser pointer in your ass and then pee in a bucket.

Cool now i have to pee.

Try putting a laser in the flow and post the results

You can get small lasers that fit in the bore of a firearm. Are people still doing bod mod stuff?

nintendolunchbox
The laser is reflecting off the surface of the water like a mirror, bouncing farther down the stream
DeadeicPrints
Interesting. Sometimes I forget light isnt something physical (maybe?) that can just push thru things and do its own stuff.

TIR
AdrianDunne
If it were total internal reflection, would light be escaping all down the path of the flow like that?

so, water optic?

Can't use laminar fiber to make lamellar armor unfortunately.
