What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

During the trial it was revealed that McDonald’s knew that heating their coffee to this temperature would be dangerous, but they did it anyways because it would save them money. When you serve coffee that is too hot to drink, it will take much longer for a person to drink their coffee, which means that McDonald’s will not have to give out as many free refills of coffee. This policy by the fast food chain is the reason the jury awarded $2.7 million dollars in punitive damages in the McDonald's hot coffee case. Punitive damages are meant to punish the defendant for their inappropriate business practice.

It fused her labia together. The coffee was so hot and the burns were so bad that her labia fused together.

[–] [email protected] 7 points 1 year ago (2 children)

how the fuck does coffee even get that hot?

[–] [email protected] 16 points 1 year ago (2 children)

Step one: keep it on a hot plate that keeps it at 200° so that you can serve it longer

That is all the steps

[–] [email protected] 4 points 1 year ago (2 children)

There is an additional step:

  • Serve it in a disposable container that doesn't soak up any of the heat.

Pouring hot coffee into a thick cold porcelain cup, tends to quickly cool it down to drinkable levels. A flimsy paper cup... not so much.

And now imagine giving that to a person in a moving vehicle without a lid.

There's so much fucked up here it's almost unbelievable. This is legitimately a bigger safety risk, after all is said and done, than many risks in an industrial chemical plant.

but water only goes to 100 degrees, even with other stuff dissolved i can't imagine a water-based liquid going much higher than like 120 degrees at most..

[–] [email protected] 22 points 1 year ago* (last edited 1 year ago) (2 children)

200 Fahrenheit. That's 93.3C. Just below literal boiling.

Edit for more information, an adult human will suffer 3rd degree burns if exposed to 150F (65.5C) liquid for two seconds. This was 133% hotter than liquid that will cause 3rd degree burns. And it was poured directly in her lap, soaked into cloth that she could not easily remove. This was straight up evil levels of negligent.

Just a quick note but neither Celsius nor Fahrenheit degrees can be used the way you’ve described - 200°F isn’t 133% of the temperature of 150°C and neither is 93.3°C 133% hotter than 65.5°C because the ‘zero’ point on both of those scales are entirely arbitrary.

The two temperatures you’re talking about are ~366.45 K and ~338.65 K, as kelvin is the only true SI measurement for temperature whose zero point describes a natural or true zero, meaning that the higher temperature is roughly ~8% hotter.

I was a bit annoyed at the nitpickiness of this comment until I saw that you're from the NDP. I salute your good work and consider myself more educated.

[–] [email protected] 1 points 1 year ago

To add on, even when something isn't boiling, it'll generate an appreciable amount of vapor. The boiling point is just the temperature at which bubbles form within the liquid. The top surface is still going to give off hot steam. I honestly don't know if near boiling vs boiling is a meaningful distinction in terms of how dangerous it is.

I wonder actually if a boiling liquid would be slightly safer because there's more vapor and less liquid.

They're using the stupid units.

We're talking bald eagle units

Humans being fragile creatures is how

[–] [email protected] 2 points 1 year ago (1 children)

So if you get 3rd degree burns on your pelvic area and you go to the hospital, they should just tell you to stop being fragile?

[–] [email protected] 1 points 1 year ago* (last edited 1 year ago) (2 children)

What? No, hot water is bad because people are fragile. I was being serious; this isn't some jab, it's just life

[–] [email protected] 2 points 1 year ago

Sorry, I misunderstood your post. It seemed like you were saying she was weak and fragile for getting burned. I read it as she should have “rubbed some dirt on it and walked it off”.

[–] [email protected] 1 points 1 year ago

Don't worry dude. I understood what you were saying. Not sure why so many people took it a weirs direction
