The message
from Tony Bryer contains these words:

If you pour 'em out into a jar they'll stay liquid for some time,
merrily boiling away as they absorb energy from the surroundings to
achieve their latent heat of evaporation.

Doesn't this turn the surrounding area into an unexploded bomb?

Potentially, yes. There can be a rather steep learning curve regarding
fire precautions. In practice, outdoors and avoiding outrageous
quantities (no buckets full) then it's mostly OK.
