    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!






  • This is one thing I love about having old but reliable cars. Our bigger family car that my wife drives is banged up in so many ways but I can just ignore it. As long as the mirrors work I don’t have to worry about how many scratches are on the housing, and as long as the tires hold air it’s easier to ignore the wheels that look like somebody was practicing their angle grinder technique.

    And then with my little commuter car, even though I like to park far away and I don’t drive into shit, I still don’t have to worry about other people or keeping it looking clean, etc.

    In general I find it liberating and good for the ol’ mental health to not obsess over superficial qualities of material possessions. So if I can make it easier to do that, it’s a win.




  • 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.


  • Yep, that sounds pretty on-brand for the types I was thinking of.

    They react so poorly to the mere existence of people who they see as other/weird that just your choice of diet not only annoys them but somehow personally insults them.

    I mean how many things could we list that drive conservatives to “they are attacking/destroying our way of life!” just by existing or seeking equality. The paranoia and persecution complexes just follow from there.

    Yep. Imagine you’re off in space such that you, the sun, and the earth make an equilateral triangle. The sun disappears, then after 8 minutes you see it disappear. Then after ANOTHER 8 minutes you see the earth go dark, because that light had to cover two of the 8-light-minute long legs of the triangle.
