I think the guy who gave me my first FE also recommended a thing that
looks like a vinyl ketchup bottle, all red, with a screw on pointed
cap with a hole in it and something inside. He keeps it in his
kitchen to sprinkle on small fires.

Also the CO2 extinguishers are probably testable. IIUC a short
squeeze of the handle only puts out a little, and CO2 ones are bigger
in the first place. But I've never had one. For one thing,
they're more money, take up more space and they aren't ABC.

I forget which letter is missing, but it seemed important.
