    Powerful oxidizers are dangerous stuff!

    One I’ve learned about recently (and used) is potassium permanganate. One of its uses is for improving water quality in fish ponds. It oxidizes basically all organic matter. It can simultaneously knock out algae, bacteria, parasites, hormones, and other excess organic waste. And the pathogens it kills can’t build up resistance to it like they would an antibiotic or poison, so it can be used preventively without creating stronger bugs. You can’t really build resistance to BURNING outside video games.

    But that also means that if you add too much, you can just as easily sterilize all life in a body of water, including fish and anything else you want to keep.

    AND it means you need to be careful when handling it. If you burn your eyes or your lungs, it makes them stop working!








  • As an American, this line short circuited my brain:

    Police there still carry guns on the regular

    I live in a quiet but growing suburban town that’s closer to rural areas than the nearest city. When I walk my kid to elementary school (how European of us, lol) the police officer working as a crossing guard for the kids still has their gun, taser, bulletproof vest, and all their other gear on.

    And it’s not a school-specific thing. You just never see cops without their weapons here. Armed and armored is just part of the uniform, essentially.








  • We should all be decent, empathetic, and compassionate enough people that the demographic breakdown doesn’t create a negative effect like that.

    I’m one of the many cis dudes here, and I just cannot get offended when it gets pointed out that other dudes can be assholes. Or that other Americans can be assholes. Or other humans, for that matter.
