Apparently ya'll didn't leave 'em in long enough to warm 'em up completely. Saw more dan a couple of unpunched cans 'empty' da pot when dey 'exploded'.
My
C-RAT story. My top locker shelf was always nearly full of H&MFs. Dat hot plate was da bestest item I carried across da 'pond' from da land of da big BX and round eyes (aka US of A)!!!
To keep dis 'vaping' related, I once did get a green & red labelled four cig pack of Lucky Strikes (in '67). What's puzzling is that LS went to da red & white packaging in '42. C-rats came out in '58. Have yet to find out da two dates connection (yes, have spent many hours 'digging' online).
Unfortunately, I opened da pack and lit one... just imagine a det cord fuse... *poooooof*. Dat pack unopened today could pay for whatever PV I could ever want!
