  • Ammonium nitrate isn’t dangerous.

    It’s not gunpowder, it’s not rocket propellant, it’s not liquified natural gas

    you need extreme heat and fuel to make it detonate, in the Beirut case that was given by nearby stored fireworks, but otherwise it’s pretty safe to use, you can blast it with a blowtorch and it doesn’t even burn

    The misconception of it being explosive comes from the fact that people buy it as fertilizer and then use it to make bombs by mixing it with fuel and other primary and secondary explosives (or just to have some fun with homemade gunpowder), and even then, usually you use potassium nitrate, a derivative of ammonium nitrate, because the ammonium nitrate is just so goddamn hard to detonate

    Now, should they accept the ship? I don’t know, as far as I know Russia’s regulations might as well allow storage of ammonium nitrate inside the ship’s fuel tanks, but some simple checks would mitigate 99.99999% of risks.

    That said, it’s still Russia and we shouldn’t be giving it money anyways, but I’m not gonna get into politics here







  • How people are so confident in sharing their DNA, something you cannot change, that you will carry on for your entire life, and that can uniquely identify you with just a small sample, to a private, profit-driven company still amazes me

    And the worst part is, even if you’re careful about it, all that’s needed is a relative doing it and now the company can basically tell most of your family tree

    And all for what, knowing the parents of the parents of your parents come from some neighboring country? No shit, Sherlock, people move around











  • 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


  • 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
