That's something that's gone the way of things like don't pour hot water on a frozen windshield.
Good advice in the '50s, but meaningless today.

Well you are trying to convince the wrong guy me and the local Smith’s store had words over a can of bean with bacon soup. Let’s just say picture bean with bacon soup mixed with drier lent. ;-(
Yes you are mostly right J, but it only takes that one can....
I ran across a swollen can at Walmart a few months ago. Looked like it was ready to blow.
I still get swollen cans, I have one right now, a can of Bumble Bee tuna of a batch I purchased in 2004.
Months ago it was a can of Ro-tel tomatoes that swelled on me, I get them occasionally.
