Neither was hurt. Both blamed the other guy for the explosion.
Honestly for two really smart guys they were sometimes incredibly dense!
Ex once ate out of date chicken and got sick. How is this something a 25 year old postgrad student does?
Haha classic Kevin moment. You’d really think someone studying physics would realise this would happen.
If you’re trying to heat/cook something in a sealed can, it's **absolutely critical** to keep the temperature below the boiling point.
As the temperature rises, thermal expansion of the contents of the can causes the pressure to rise inside the can. The increased pressure causes the boiling point inside the can to rise above the boiling point at ambient pressure.
If you heat it past the boiling point inside the can, some of the water inside the can will vaporise (turning into steam). This phase change (liquid to vapour) causes a large increase in pressure, which the can is not designed to contain. The can will rupture.
When the can ruptures, the pressure is released, and quickly equalises with ambient pressure in the room. This causes the boiling point to fall back to the normal temperature at ambient pressure. As the content of the can is now at a significantly higher temperature than its boiling point, a lot of the water content will suddenly vaporise and hence expand rapidly. This results in a [boiling liquid expanding vapour explosion](https://en.m.wikipedia.org/wiki/Boiling_liquid_expanding_vapor_explosion), or BLEVE.
Now I can understand a ten-year-old not realising that boiling a can won’t end well, but anyone who’s reached their late teens knows this, even if they don't understand the physics behind it. I mean, when I was a teenager, I knew of guys who got drunk and put cans of baked beans in a camp fire as a dare, realising it was dangerous. There’s really no excuse for a physics student.
If I have learned one thing about people smart enough to be scientists I have learned that they manage to be simultaneously incredibly daft.
Can explain nuclear fusion to me, an art student who sucked at maths, and I can understand it- this is a skill!
Cannot keep living space tidy, thinks we don’t have to clean a bathroom because “water goes through it”, aye expired chicken and got sick, needed help dealing with city council taxes because forgot to fill in exemption form, so so many lost keys, pairs of glasses, socks, usb sticks with important coursework and in one case a single shoe.
Like, I guess really really smart people used common sense as their dump stat? I am not particularly smart but I have been able to at least semi reliably look after myself since I was about 12. I know not to eat expired chicken or drink Green milk and that you should designate one place for keys in your house.
Eventually this one guy moved back home and we broke up. A mutual friend has told us he is married now. I really, really hope he has at least learned from the chicken incident.
Possibly, I suspect his family took the same approach that mine did where admitting that their kid probably needed more help with stuff was something they would never do.
Mythbusters. Hot water tank rocket. Same thing from different angle. If the *bottom* of the can had blown out, it would have looked like a scale model of *Sea Dragon* launching, but covering anyone near the stove with super-hot thickened condensed milk.
Which would not be fun.
The shrapnel could've killed/injured them. Especially combined with molten sugar lava.
In an alternate universe you would've come home to a very gruesome scene. D:
...Did they not open the can?
They were lucky, it makes me remember a case where a guy died doing something just as dumb.
He bought a lava lamp and plugged it. It takes some time for it to heat up and start moving. The guy was an impatient moron, so instead of simply waiting for it to heat up enough, he put it on the stove and turned the stove on. It did heat up faster, enough for the lamp to explode. He was right next to it to look at it, so it exploded right in his face and killed him.
If I remember correctly, there was a warning on my lava lamp that said not to do that. I don't know if that warning already existed before his death or if it was added after.
If it weren't for the use of "flatmate" (I'm in the US), I'd think I knew these Kevins. I dated one of them for a bit. Brilliant guys, but when it came to real-life common sense...things like this happened.
Yeah, I dated Kevin 1, Kevin 2 definitely detracted from the common sense quotient, otherwise Kevin 1 was mostly pretty smart. Apart from eating expired chicken because I still have no idea why you would do that 🙃

To be fair, that is a common way to make dulce de leche. They just messed up the process somewhere!
OK, but how did they manage to make it explode? That part I have never quite worked out.
With high heat. The water should be a very low simmer, or in a Crock-Pot full of water. It's delicious on ~~a spoon~~ ice cream, cookies, toast etc
Ah, this makes sense as I think they just whacked it in a pan and turned the heat right up.
JFC lol
🤣🤣🤣🤣 OMG, I’m choking! I promise I wouldn’t be laughing this hard had they gotten hurt, but . . .

You don't fully submerge it, you have to open the can 😂
This would also make sense.
Wait. THEY DIDN’T OPEN IT? holy shit I agree with you. how are they alive.
They forgot to open the can, and it EXPLOSIVELY released its contents. Under pressure.
Yep. This is how I make it. Maybe they didn't keep the can covered with water? Heat too high?
"making each other worse and increase the potential for Kevining" 🤣omfg, that's a classic statement. Kevining. I'm gonna put that one under my hat!

Well, scientists hyperfocusing on their field of study and being somewhat scatterbrained outside of that isn't a stereotype for no reason...
Your description there is textbook ADHD btw!

I have an idea! Metal conducts heat, so let's wrap the lasagna in foil when we microwave it so it cooks faster!
Prepare for trouble, and make it double!

I know this. Honestly I have no idea how no one was seriously hurt.

Real life Home Improvement, with real life TimTaylors. Too bad you weren't able to record their experiment... I bet it would have gone viral.
Yeah, my mom used to do this to make caramel from condensed milk. Every now and again, we'd have a can explode
