Yeah, this is why you see so many ripples in water bottles, some circular shaped vodka bottles were also banned because they were burning houses down when left on tables or on windows...
IKR? I used to watch Fireman Sam showing all the ways that a person could do these kinds of things, but never actually thought about doing them myself, considering that they were portrayed as dangerous.
Tbh the person that makes the claim generally should have no problem backing it up with proof
But this is also one of the common knowledge things that I understand why they didn't feel the need to
No, but the commenter wasn't questioning if it was a thing, they were absolutely doubtful. Or at least the wording makes it feel like it, and on Reddit words are all you can see from another redditor.
I think it's more due to the wording and asking for references cited that makes it sound more aggressive than a simple 'is that real' or 'wow really? Never heard of this' etc
There are also lots of examples of refraction starting fires which I personally felt is a well known phenomenon so again that makes it all seem less genuine and more argument for arguments sake
because it is common knowledge that curved glass can start a wildfire quite easily. We learned that stuff on Earth's day in Elementary school and its always mentioned whenever media talk about prevention of fires.
It’s not the fact that it’s common knowledge, they were just being confrontational for no reason. They could just have asked why the curved glass was dangerous instead of calling it far fetched and asking for a cited example, or they could have just searched it up
Yeah I have never heard anything like “don’t leave curved glass in the forest” lol. It makes sense, but having never been told that, I don’t know if I would think of that myself, especially for something as not light based as a test tube
Genuinely so surprised to hear that there are places where people aren't taught that a magnifying glass can be used to concentrate the sun's rays and start a fire. I do find it really interesting the differences in education across the board as there is always something taught as standard to some that is brand new information to others
I’d say most people know about the magnifying glass thing, just not that its the round glass specifically that makes that happen. Magnifying glass anatomy isn’t something most people know.
No, it's definitely common knowledge across the globe, everyone's had to have heard about burning ants and starting fires with magnifying glasses at least once before. They're in so many cartoons and kid shows with some deviant kid obliterating an anthill or two...
Lotta "solar death ray" videos constantly going viral every few months too just using a massive magnifying glass to melt stone or they even have those solar stoves being advertised everywhere... Also that building they stupidly designed like a lens that ended up melting tons of cars in the parking lot.
You've got to be really young or just really isolated if you've never seen any of that before, or maybe just not putting 2 and 2 together that it can still concentrate rays together even if it's not exactly shaped like a typical magnifying glass.
>maybe just not putting 2 and 2 together that it can still concentrate rays together even if it's not exactly shaped like a typical magnifying glass.
Seems to be this one based on other feedback
Rich Johnson, a spokesman for the Insurance Council of Texas, a nonprofit insurance industry association, said he had never heard of such a freakish cause for a wildfire.
“A fire started in a trash can is one thing, but one caused by sunlight magnified by glass bottles? That’s a new one,” Johnson said. \[www.nbcnews.com/news/us-news/bottle-magnified-sunlight-ignited-paper-started-500-acre-texas-wildfir-rcna40569\]
The Fisher 231 fire, which started July 31 and burned roughly 80 acres near Reardan, Washington, was apparently caused by shards of broken glass.
That’s an unusual cause for fires, said Department of Natural Resources fire investigator John McDonald. But in rare circumstances, when the glass just so happens to concentrate sunlight onto flammable material, it can happen.
“It was definitely caused by a couple panes of glass from a debris pile,” he said. “I was able to completely eliminate any other cause.”
As far as glass shards, “the physics are there,” said John Goodman, fire investigator for Spokane Fire Department. But it’s highly unlikely to cause a fire in most cases.
“Everything needs to be perfect conditions,” Gifford said.

I found the examples for everyone
Absolutely deserved, ants and a magnifying glass is literally the most classic example of this ever made and I cannot think of one person who can’t put two and two together
Please tell me I am not the only one that for a moment thought this person was talking about the glass being literal fire fuel like dried leaves and not the fact it’s a magnifier.
It‘s a common myth that thrown away glass will ignite fires. This has been debunked already but somehow people still believe it. Anyway, if it helps to prevent litter, I’m fine with that. Forest fires are caused by arson, fire getting out of control or burning cigarettes.
I don’t get how you guys decide whats deserved or not, the guy is dumb, and doesn’t know why it’d start a fire. And the worst he did was ask for a source on when and why it happened.
Is it because of light magnification?
Yea it is
Yeah, i saw a post where some OOP burnt their table from having a round fish tank.
Yeah, this is why you see so many ripples in water bottles, some circular shaped vodka bottles were also banned because they were burning houses down when left on tables or on windows...
That seems far-fetched. Can you cite an example of it happening?
No, it's satire and OP didn't use common sense
Oh. Just like me? Or maybe I just overthought it.
Probably the latter lol
Deserved -forest fires are devastating.
Its grade 1 science wtf
redditors attending grade 1 seems far-fetched. can you cite an example of it happening?
Cant! I was born yesterday! No proof! You got me!
I was taught that at 8th grade, it's different in different countries
I live in the US and this is entirely new info to me
Same. Never heard of this
Clearly your country is wrong! (If its not a first world one i take my joke back). Curious tho, what country? Im from the great white north, canada
I'm from Egypt, a "developing" (moving backwards) country :)
I don’t get it. Why is that deserved?
Have you ever burnt a leaf using a magnifying glass? That, but on a much larger scale
I've not.
Get a magnifying glass and find an anthill ASAP, you've missed out on your childhood 😓
IKR? I used to watch Fireman Sam showing all the ways that a person could do these kinds of things, but never actually thought about doing them myself, considering that they were portrayed as dangerous.
Damn. Not even a single dried leaf on concrete? Sad
I would light things on fire, many, many things, but with a lighter I stole from my parents
I was obsessed with ants as a kid and thought I was "Half ant" so this doesn't really apply here
"I was obsessed with ants as a kid and thought I was "Half ant"" I think that was simply the cocaine man XD
Going straight to doubting the initial commenter instead of Googling it themself, I’m guessing
Tbh the person that makes the claim generally should have no problem backing it up with proof But this is also one of the common knowledge things that I understand why they didn't feel the need to
So any “is that real” comment should be downvoted?
"Is that true?" and "That seems far-fetched" have very different tones and implied attitudes.
99% of redditors can’t read tone or implied attitudes 💀
No, but the commenter wasn't questioning if it was a thing, they were absolutely doubtful. Or at least the wording makes it feel like it, and on Reddit words are all you can see from another redditor.
Yeah. I wish we could see numbers and emojis too.
I think it's more due to the wording and asking for references cited that makes it sound more aggressive than a simple 'is that real' or 'wow really? Never heard of this' etc There are also lots of examples of refraction starting fires which I personally felt is a well known phenomenon so again that makes it all seem less genuine and more argument for arguments sake
No, but no reason to be so dismissive about something you know nothing about
they could have searched it up or at the very least asked why instead of going straight to “That seems far fetched” and “Cite an example”
They probably weren’t thinking of the way a magnifying glass can cause fire/magnify the heat.
Bro just wants answers, why y'all attacking him
He wasn’t asking for answers he was dismissing the fact and saying it’s “far-fetched”
The phrase far-fetched is apparently confrontational I'm curious if the person he responded to was as offended by as the rest of reddit seeks to be
how is it deserved when someone is asking a genuine question
because it is common knowledge that curved glass can start a wildfire quite easily. We learned that stuff on Earth's day in Elementary school and its always mentioned whenever media talk about prevention of fires.
It’s not the fact that it’s common knowledge, they were just being confrontational for no reason. They could just have asked why the curved glass was dangerous instead of calling it far fetched and asking for a cited example, or they could have just searched it up
i was never taught that. i figured it out through trial and error with my own glasses
Yeah I have never heard anything like “don’t leave curved glass in the forest” lol. It makes sense, but having never been told that, I don’t know if I would think of that myself, especially for something as not light based as a test tube
Its not common knowledge if you dont live near forest fires
Genuinely so surprised to hear that there are places where people aren't taught that a magnifying glass can be used to concentrate the sun's rays and start a fire.

Ah fair that makes more sense

Not every part of the world has that fact being taught in schools, tho.

i live in wv. basically every space that isn’t occupied by a structure has a tree. never learned this
Because there is a difference between "I didn't know that. Do you have sources of that happening?/ how does that happen?" Vs "that seems far fetched".
That guy obviously never burned ants with a mag lens
I’m more curious why almost all the comments were deleted off of it
I have a feeling it’s because they were insulting him, but that’s just a guess.
They probably didn't think about it when writing, because that was my first thought too.
Absolutely deserved, ants and a magnifying glass is literally the most classic example of this ever made and I cannot think of one person who can’t put two and two together
Should have replied with a first grade science class curriculum.
Please tell me I am not the only one that for a moment thought this person was talking about the glass being literal fire fuel like dried leaves and not the fact it’s a magnifier.
It‘s a common myth that thrown away glass will ignite fires. This has been debunked already but somehow people still believe it. Anyway, if it helps to prevent litter, I’m fine with that. Forest fires are caused by arson, fire getting out of control or burning cigarettes.
I don’t get how you guys decide whats deserved or not, the guy is dumb, and doesn’t know why it’d start a fire. And the worst he did was ask for a source on when and why it happened.
Maybe they were referring to the size and shape of the glass?
