How do you open a can if you don't have a can opener at hand ?

Howdo you open a can without having a can opener at hand ?

Oddly enough the can opener wasn't invented until almost 50 years after the invention of canned food.
The hammer and chisel was the usual means of opening a can.

TNT.

You can only open a can if you can find a can opener nearby. And if one cannot find a can opener then one can dance the can can on the lid to release the pressure of the can lid and you can prise open the can.

yeah I don't see a hammer and chisel in this video but I do see some very interesting vintage can openers

Rub it on concrete.

I generally use the little ring. I pull it, and it goes "puh-WOOSH" and the frosty goodness pours forth when I tip the can.

Humor: Believing in science- Whatever way you try, that's generally fine, especially if you find something logical that works solving the problem opening up the can - except for the microwave approach (call it: Faith).

Yeah, seriously speaking I definitely wouldn't recommend putting it in the microwave, not because I have tried it myself (i haven't tried it myself), but because I suspicion that a metal can in the microwave can create a disastrous and dangerous mess, potentially where the future of microwaves would need childproofing safeguard measures to prevent that.

The question has to be what DO you have on hand?

This is the way rub it on a rock until the top edges wear away then it opens xxx
