Just wondering about this , as a youngster I found out the hard way that unopened baked beans cans go thruump when left on a campfire too long , the beans go way up in the sky ect.
Just wondering how?
Isnt the inside of a can a vaccum?
So if? there is no air to heat and expand, why does the lid get blown off?
If the can is empty would it explode as well?
Are there such things as canned bombs?.
SHOULD HAVE WARNINGS ON THEIR LABELS?

LoL, what a question.


There might not be any air in the can, .... but there is WATER, and as we all know, when you heat water it becomes steam. Too much steam and BOOOM !!

Expanding liquid as it boils has to go somewhere doesn't it?

No No No! That is all wrong! That sounds like something you would read in a science textbook written by freemasons and zionists!

When you think of beans, you think of intestinal gas. When you heat up beans, you are causing the beans to release gas just like they do in your intestines. The explosion you are seeing from the can farting!

What an irony that you Inastella Burst answers Dr Expireds question on exploding Vaccum cans?
I feel like Prof Airhead but I honestly hadnt thought of the water content.
So do you think a vaccum canned can of water would explode?
An empty vaccum can nothing would happen?
An air filled sealed can?

Many beans are lonely. When the get warmed up they start to have stronger feelings and begin to vent their frustrations. This leads to can-ableism and in the ensuing panic the other beans run like hell. :->

Good humor post there, and it follows the facts good on ya for using your bean.
But it can be a serious subject , a late friend when he was young had a can of baked beans explode in his face, he had to go to Hospital and have the beans removed from his skin, he had bean stains on his face for weeks.
Its one of those things that no one thinks about until they go shooting up in the sky and there is no dinner at the campsite.
I tried canned potatoes too but the beans make the loudest bang.

every one knows
beans are filled with toot gas

when you eat them
it warms the toot gas up in your intestine
and well
you know...
the toot gas, struggling to be free of the repressive regime that
keeps it chained to the endless grindstone of capitalist production
bursts forth like a little alien out of a character actors chest at the dinner table
YOU don't explode because you are not an enclosed space.

A can IS an enclosed space
and a fire heats the toot gas
to a much higher temperature and pressure

At a certain amount of pounds per square inch the toot gas can no longer stand it self....
and since cans do not have an out put jack
the toot gas which has been yearning to be free
like the money in a teenagers pocket on his first pay day
bursts forth like Dolly Partons boobs out of a too tight dress

We seem to have more than one plausible theory, I lean to the steam one,but the Toot gas sounds feasible perhaps its a combination of both that gives the exploding Baked bean can so lethal?
Lets hope the news of a giant baked bean bomb never surfaces, I would imagine the camp fire would have to be huge to heat up a 15kg can of beans?
Steam and Toot gas ?
Steam only?
Toot Gas only?
Time to use our beans and get the definitive answer posted?

Unfortunately even beans are subject to the Ideal Gas Law inwhich;
PV=nRT. When you raise the temp you raise the pressure. Enough pressure and boom, a waste of a good can of beans.

Probably about 98% steam and 2% other. Not sure if toot gas is really a factor in the 2%, I thought toot gas was a byproduct of digestion and heating the contents isn't the same as digesting them.

Other would be thermal coefficient of expansion of contents other than water, and possibly other volatiles expanding.

Top tip of the day....pierce the can first.


Saves losing your dinner and a trip to the burns unit.
