Sorry to introduce a discordant note . . . I 'went off' MF quite a few years ago ─ I used to make small pyro squibs for the garden (about half a
gram in duct-tape with visco), which went with a satisfying "thump" and flash, visible in full sunlight.
The children loved them but the large quantities of mercuric residues on the grass bothered me greatly as I have cats and many other animals visit
from time to time . . .
I'd later find myself carefully (and tediously) brushing all residues off the grass into the soil beneath!
And fuck it, silver azide, greener though it is, never just deflagrates at all.
