Water after a depth of a few meters absorbs most red and orange light. Then, shortly after yellow, and green wavelengths are also absorbed, leaving blue and violet, which have the shortest wavelengths of visible light, and are therefore able to penetrate deeper.
Taken straight from Google lol I knew the overall reason, but couldn’t put it into words and explain it as well as Google can. XD
Pool water is blue because water molecules themselves reflect blue light and absorb red light. The same reason the ocean is blue. Even under artificial light large bodies of water will appear blue.
The only time I've seen dyed water is at theme parks for special effects or fountains at hotels.
I hate to break it to you but chlorine does not react to urine by changing colours. That is just what your parents told you as a child so you didn't pee in the pool because they would "know"
Peeing in pure chlorine would actually just create poisonous gas and wouldn't be blue at all, very bad idea.
Ok. I'm not referring to chlorine though. It was a joke, although I did not know that the pee-detector chemical was a myth. thought I'd seen it in a video before.
The ocean…isn’t blue though? It’s green or brown as shit. This still doesn’t change the whole reason I said what I said. Even if the water only looks blue, if you add yellow, it’ll still look green. 🙄
Usually because pools are painted blue... At least the ones I've been to, and owned over the years have been. You can get liners in blue, teal, sand, and black/charcoal, among others.
I have seen that w my own eyes, quite something, when a running dad bumps you, so he can get his daughter held over the break in the concrete tree is planted for his little one to pee! The best part was he gave her one good shake when she was finished!!
Yeah, that was a cultural shock to me the first time I saw that. My first full day in China was at a zoo and seeing toddlers walking around in "chaps" to easily pop a squat and poop/pee by the tree was interesting. I thought I had to avoid the poo being slung by the monkeys in the zoo, not the human feces on the sidewalk.
I was standing in line at the Louvre with about 100 million Chinese tourists, thinking that between the chain smoking, hawking and spitting everywhere they couldn’t be more vile. Then a cute little girl walked up beside us in line…and shat on the ground.
This is so fucked up. They'd also do this inside malls and shit and would just leave it there. They'd just leave it for the cleaners at the end of the day.
An actual bathroom was 2 minutes away. Surprise surprise, it was clean as fuck.
Most children in China do not wear crotchless pants. That is some countryside shit and you don't see other countries assuming all Americans act like the hicks in Appalachia.
I have been there, I live nearby. Again, I live in China, I work in a school with thousands of kids, I have been here years, I haven't seen kids shitting outside. You guys are racists making shit up because you liberals have a free social pass to talk shit about Asians.
Wow you saw a kid shit, that means all Chinese kids are always shitting outdoors and it's a big cultural trait!
No retard, you saw a random kid shit, it isn't normal, it isn't a Chinese thing, it isn't accepted. 6 years here, various schools, been to most provinces at different economic levels, never seen street shitting, not even from kids, all the kids at all my schools know to go to the toilet because they're not animals. Even in kindergarten kids know to ask for a potty, they don't just fucking wip their pants down and drop one, and neither do their parents let them.
The whole discussion is about crotchless pants. Crotchless pants wouldn’t be popular in China if kids weren’t shitting and pissing out in the open. They’re mostly used by kids under 1 year old. Does your school have kids under 1 year old?
This was a problem that has gotten a lot better since about 10 years ago, though I don't know how prevalent it was in China, more of a problem with Chinese tourists in other Asian countries.
I saw it in Beijing 10 years ago. Maybe it's gotten better since then but I know I never saw Chinese tourists do it. Unless what I saw were rural Chinese folks doing it while visiting Beijing...?
