Can Trivia:
Wasn't until 1995 that all cans in the US had to be lead free.
"Tin Can" came from most early cans being made from tin plated steel (still quite common).
Acidic foods in tin plated cans can disolve enough tin to make you sick.
- (unlikely now a days due to different interior linings)
Older folks know that if you ever open a can and there's an escape of gas, don't eat it!
Reason for the gas pressure is that the contents have/had microbes that multiplied, tainting the contents, possibly to a leathal level.
Also why "dented cans" used to be sold at a discount. The dented can were more likely to have a compromised seam, leading to microbial contamination.
As far as making/crafting a can for oil. Would be fairly trivial. Thin sheet metal & lead would do. A chunk of anything with a bit of point for a heat source to solder with; like a large bolt, or a wrench, heated in a camp fire would suffice for a soldering iron. The ridges in modern cans allow a thinner walled can to be 'tougher', less likely to dent/crush.
Sorry, was a bit bored, heh
--Edit: forgot I had something on topic to say, doh!
For a Stealth build on Horde Night: maybe a chance to land their Hidden Strike crit damage? Even though alll the Zs already know
[Edit2: do to Mechanimal correcting "their" for "they're". Thanks Mech!
] they're there?
May not even need to be crouched. Just a ramped up percentage chance to land a 2-3x crit hit.
Might make it farily straightforward to balance vs. other builds?
