Some species of legumes have a glutamate analog that can kill if ingested regularly. The resulting disease is called Lathyrism which is caused by
Oxalyldiaminopropionic acid (ODAP) and entails slow nervous system degeneration. Talk about a real bummer

Yeah, we were about to say, the most common rust remover in the USA (whinks) is 2% HF, not 10%

1%, not 10%

Maybe if you only buy canned beans. Raw beans are in fact very toxic as the previous poster said, due to phytohaemagglutinins. Beans must be boiled
(not merely heated) for at least ten minutes in order to be safe to consume, although, for taste reasons, most people would cook them longer.

In the US it is 1%, but here in Europe i can find it as a 10% solution! It's cheap too, at the local grocery it costs 0,90€ for 50 ml. (https://www.amazon.it/Rapida-RAPIDA-TOGLIRUGGINE-50ML/dp/B00...) I find quite ironic that they ban much less dangerous stuff while this lethal
acid is sold very easily.

"Fun" fact: there has been zero recorded methanol poisonings from home-distilled liquors ever. It has always been adulterated with added methanol,
either unknowingly or accidentally. Tired of noting people on this myth when they always jump on their back feet when talking about home distilling.
Not an actual form of chemophobia, but some false myths die hard. |
I think blowtorching a copper wire to red hot and then dunking it in
will tell if methanol is present as formaldehyde will form.apparently
a sniff test will tell

howz about lead, copper, brass and lead styphnate? sold as an all in one kit by blazer, winchester, federal etc. and can be applied with easily
obtainable dosing device using a simple point and click interface? the amounts required for toxicity are extremely variable...almost to the point of
random and as such, a modicum of care and attention should be used handling these otc materials.
some of my personal favorites.

Why even discard the forerun then?
Is it sort of a urban myth, that self-burned liquor will give you methanol poisoning?
Because apparently it is impossible to get methanol poisoning from that, there is just too much methanol-antidote in it.
Its a big talking point against moonshining though... guess thats why they keep that one up.

Already mentioned above by panache. Yes lead is toxic at 367m/s.
I think it's a good one.

This might work, but I wouldn't bet my life or eyesight on it. You only need few % of methanol to cause danger, and amounts of formaldehyde produced
could be too small - alongside with acetaldehyde and other decomposition products - to smell. Flame color tests are also absolute bunk. Only remotely
useful way to quickly determine alcohol proof from dilute to concentrated is to shake the bottle, alcohol tends to "foam" distinctively compared to
water, but it clarifies very quickly.

Because of the taste.
Germans got a drink called Schnapps that contains all of it, and to some it tastes fruity, to some just burning strong varnish-like.
For moonshiners and vodka, foreshots, heads, hearts and tails are collected in about 5/30/50/15 ratio, if even more neutral profile is desired, hearts
cut will be less than 50%. Cuts are collected in small fractions, for example in 20-30 different containers for the whole run, for 2dL glasses it
equals to 3-5 liters of collect. This separation is usually done through classical bioassay - smell and taste test.
I still stand behind my saying: present one case that moonshine has blinded/killed anyone through methanol poisoning through batch that has got only
yeast-brewed alcohols in it. 100% of cases contained adulterated products, usually by accident, sometimes intentionally or through absolute stupidity.
Cases where car radiators have been used as condensers, containing methanol or glycols have been documented.
In Europe there were a case where an IBC container labelled "methanol" was found as the culprit of a mass poisoning of criminal alcohol supply chain,
because someone thought that little "m" in front of ethanol couldn't make that big of a difference. I think it's an analogue to some amateur chemists
regarding isomers of compounds (L? D? who gives an aRse(pun intended)), or Xylenes, which has para,ortho,meta-isomers, for most, it's just plain
Xylene. In some cases it doesn't matter for the intended use, in some cases it's a choice between happiness and death. (Read: https://en.wikipedia.org/wiki/Enantiopure_drug#Examples)
This argument is still one of the first to pop up when home distilling surfaces anywhere, and as all of the other urban legends, this one is full bunk
too.

"canned air"
difluoroethane is commonly used
at my job we have had a few people hospitalized after warmwater pipes turned our whole factory into a gas explosion and people went in right after the
explosion
turns out, the insulating foam is made using a blowing agent containing some carbonfluorine compound
and that fluorine ion persists after it burns, difluoroethane for instance turns into hydrogen fluoride
carbon fluoro chemicals is my take, very dangerous and you can pull them out of refridgerators or maybe sneak some out of your mechanic, they tend to
have it standing around for refilling aircondition units
oh and as a fellow chemist i knew from long back found out- ethylene glycol, you just get intoxicated like alcohol, it tastes sweet and it turns into
carbon monoxide (iirc) so you pass out and never wake up again
im sure EG has been used to kill people mixed up with alcohol, imagine how many people dont notice their drink suddenly being disgustingly salty? how
would anyone live to tell about a minor taste difference from ethylene glycol

Ethylene glycol turns into oxalic acid in the body

The ricinus beans I got from my 2020 plant are doing quite well! I only planted them in April. I had the beans in the fridge since harvesting them and
I expected only a few to germinate last April, but at least 80-90% did. I planted 7 of them in my garden (I have a garden now) and kept the 4 biggest.
Two of them grew large enough to keep sunlight from the other two, keeping them small. Only five months after germination they are 2.8 meters tall and
producing beans as we speak.
I will keep some of the beans and germinate in February next year. I wonder how big I can get them. They seem to have reached ground water early on,
as I never had to water them while the summer has been very dry.
Lets see when the bananas next to them grow larger.... I've got sikkimensis growing, hopefully they survive winter.
