If you use metho on jellyfish stings, like old first aid books used to recommend, ALL the stingers in the tenticle fire off. I did a first aid course a few years back, when a scientist from JCU here in Townsville came to give a talk on jellyfish stings. As it turned out, this scientist, whose name escapes me, is the man responsible for the now common use of vinegar.
The story he told was, while he was testing other substances on box jelly tenticles under a microscope, tested samples of tenticle were removed from under the scope and dosed with metho, to neutralize the stingers.
By accident and only by accident, while testing tenticle under the scope, he added metho while he was looking through the lens. ALL the stingers in the test sample of tenticle fired off instantly. So the lesson here is don't let granny pour metho on you!
