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.
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
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.
Well, you could say beer is yeast piss.
I'll have another (lab brewed yeast piss. From malted grain. Sometimes with hops)
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?
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
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.
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!
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.
