MrUnderbridge posted:It does seem like weed breeders and consumers have come to the conclusion that "lots of terpenes = better weed". Is anyone putting weed extract through an industrial fractionating column so they can reassemble their custom blend exactly to their desires? Have it be like those blended soft-drink machines, you put in your recipe and it spits out a cart.

who needs weed when you can take DHEA or pregnenolone and get the potentially nasty heart side-effects with none of the fun also, explosions&fire + extractions&ire is really funny so whoever mentioned that, good recommendation. It's especially funny when he goes on a rant to the point of passing out about a mostly unrelated topic. nuclear detonations on mars lol

hello thread, can I consult your explosion-honed brains? I'm writing a book that has a kid trying, incompetently, to burn down a building. He has a can full of petrol with maybe an inch of air in the top. he opens it, waits 30 seconds, and drops a lit match in. What happens?

I think that you’ll get a fwoosh as the gas vapor–air mixture in the can and the open air above burns. The you have maybe a fist‐sized flame coming out of the mouth. If the can is plastic, things rapidly get more energetic as the can melts and burns, liberating more gasoline. If the can is metal, the flame grows as the heat causes the gas to evaporate more and more rapidly in a feedback loop. Disclaimer: while I have played with my share of fire, I never did anything that dumb. So I’m basing this on smaller “experiments”, plus secondhand observations. https://www.youtube.com/watch?v=FPKen4QwY7I&t=56s https://www.youtube.com/watch?v=MYqp4-GVM84 https://www.youtube.com/watch?v=JBw5RiNqRFQ&t=68s

Gasoline doesn't really burn, just the vapour, and the fuel-air ratio for gasoline is sensitive (go ask in AI), and there's not a lot of vapour in the top inch. So your match would go out. Maybe a gout of flame from the can as the vapour ignited and used up all the oxygen inside the can but it wouldn't keep burning. Probably. Surface area - oily rags act like wicks, pouring it out onto stuff gets you the big clouds of vapourized petrol to get it going.

Bolded the important part. Both of these scenarios are plausible because the A/F ratio is so sensitive. If it were diesel, then the match goes out. If it were acetone, then a bad time is about to occur. With gasoline, it could be either. If it's E85 gasoline, then entrained water does WEIRD things to it. Write what works for your plot.

I was going to say, you can easily design an experiment with small amounts of regular gasoline, a smaller container and a similar or even exact air-to-surface area ratio while taking care of safety concerns like fire suppression, protection, distance from ignition at a location that doesn't burn but it's a pain in the rear end. With like 10 trials, it'd probably ratio out to a few smotherings and some catches, depending on how much air could be circulated or was initially available near the vapor. if you don't regularly do stuff like this tho and have training on how to stop a fire with a rapidly combustible source, it's not safe to try.

Where people tend to get into trouble is when they toss a cupful or more of gasoline onto an already-burning fire. My dad did that once or twice, with impressive (and, very fortunately, non-injurious) results.

I use vegetable oil for this, and also to start charcoal. No idea why people use volatile hydrocarbons for that poo poo (other than fun).

The gasoline can will have different behavior if the kid drops a match in it in on a cold winter night versus having the scene take place in an attic in July.

Initially i had it just go out, but i added a little 'foof' of flame. The idea is for the reader to go 'oh no you absolute idiot child don't do that' but for the character not to actually die in a horrible explosion, and for it to be plausible, and i think I'm at the right place!

Call up your local fire station and say "Hey i'm trying to write a book, any chance y'all can tell me about fuel/air mixtures re: gasoline and maybe please help me test some things?" Then one of two things happen: You either get arrested as a suspected arsonist or a bunch of bored fire professionals will get excited to have a fun distraction for a few hours.

Now, if he filled the room with particulate flour blown around by fans and THEN was dumb enough to light a match and drop it into an ignition source...that'd basically be a poor man's thermobaric. It's two things a stupid kid could readily get - gasoline and flour.

Yeah I live real close to several sizable grain silos and whenever I drive by them I always wonder a little if I'll get to have every window in my house blow out someday because a worker tried to light a cigarette or a wire bitten by rats sparked at the wrong time.

surprised they never did the flour thing in Burn Notice. That show loved explosions and did macgyver-esque stuff all the time. Like using a high enough CO concentration + a spark to cause an explosion.

I'm guessing because doing it accurately would have exposed how all the other "dangerous" explosions were achieved via that method IRL.
