let's order strange things from NIST! first up is this jar of reference peanut butter. it's only $881 per jar!
ok technically it is only $881 per *three* jars.
but why would you want this peanut butter? it comes with certified amounts of particular substances in it, so it's good for calibrating equipment used in the food industry to measure regular ol' grocery store peanut butter.
but NIST has a lot more than just peanut butter. oh my. you won't believe the goodies i've seen!
no, what we need is some milk. you can pick fortified or unfortified milk but sorry, it's contaminated. oh also, it's human.
all right, that's not very appetizing. let's have some meat homogenate instead. actually that's probably just wet cat food

or how about some THC? yes, from marijuana. however, it's been peed out by someone and is freeze dried. how'd they collect this stuff anyway?
huh, this must be the "health food" section of the NIST store. it's only slightly more expensive than Whole Foods
anyway, feel free to browse the store yourself. https://www.nist.gov/srm
their "news and updates" section also has some amusing headlines. https://www.nist.gov/news-events/news-updates/org/5921
