Johnny was a chemists son. But Johnny is no more. What Johnny thought was H20, Was H2S04.

The one I remember from school was phrased slightly differently (but same concept) :

Poor little Jimmy is lying on the floor, for what he thought was H2O was H2SO4

Two chemists enter a bar. One orders a glass of H2O. The other chemist says I'll have a glass of H2O too. He bleached his throat and died.

Are you even sciencing if you don't drink some piss you found in a beaker somewhere?

Observation: this looks like piss} Question: is this piss?} Hypothesis: this is probably piss} Experiment: drink the piss} Analysis: tastes like piss} Conclusion: it’s piss

Yeah, check for all of that using the high fidelity, self calibrating sensory cluster.

How do you know it tastes like piss if you've never tasted piss before?

Better piss in a cup and taste it to make sure we get a nice baseline.

Thats my schoolmate, he licks everything. Including liquid nitrogen.

Worse health-wise, but probably not worse in how disgusting one would think it is to drink.

Well, you could say beer is yeast piss.

I'll have another (lab brewed yeast piss. From malted grain. Sometimes with hops)

malted grain

You mean aborted barley fetuses?

Sadly the Erlenmeyer flask was previously used for some nasty water soluble compounds and just looks clean.

rinse -> acetic acid -> rinse -> Acqua regia-> Rinse -> Pirahna solution -> Rinse -> 500°C oven -> Rinse

I would then drink from it without even worrying

Is NileRed then too cautious when he only uses fresh breakers for stuff he is going to eat?

The cost of a fresh beaker is worth mitigating the risk.

That could be argued, but where does it stop? New stir bars? New thermometer probe every time?

he's lucky to have a big enough channel to be able to afford 40000$ NMR machines, so a couple beakers aren't that much of an expense for much more safety

but as a home chemist, there is NO WAY I'm getting new beakers every time I wanna do edible chem, especially pyrex branded ones like Nile does. Lab equipment, even basic glassware, is ridiculously overpriced

Don't forget the phase-change cooling from the addition of solid state H20.

No, they're talking about a ridiculously high mass isotope of Hydrogen. Turns out it has some wacky properties.

lab grade ethanol

That's usually methylated spirit. It probably won't kill you, but you'll lose your vision.

1

methylated spirits are the ones used for cleaning, lab grade ethanol needs to be just ethanol or some reactions might fail, however in some badly managed labs you might find mislabeled stuff and have contaminants

still, you shouldn't drink it anyways, as some producers use the highly carcinogenic benzene to make pure 100% ethanol, as distillation with water can only get you up to the 95,6% azeotrope, and some benzene might make it's way in the product

I remember reading about a chemistry teacher found dead one morning. he had a habit of consuming the laboratory's ethanol after hours, and the night before had accidentally poured himself a glass of methanol

I themed the wet bar in my basement as a laboratory. There's a drying rack on the wall that I use to store 15 mL beakers that I use a shot glasses. It's fun. I've also found that a hot plate stirer with a thermometer probe and a vacuum filtration setup makes the best clarified butter easy as a snap!

Unless you're drinking port, in which case you legally have to yell "TO INDUSTRY!"

I'm just glad she's wearing earings and makeup like a good female.

Have we communally decided where the proper line should be drawn between lifestyle acceptance, and calling out stereotypes in media? I get what you're insinuating, but some women do actually seem to enjoy wearing earrings. You could just as notably call out the fact that she has long hair.

Some women also commit suicide by drinking lethal chemicals, but that doesn't mean this picture makes sense.
