      Yep the rule is always to bleach the things that need it and do everything else while you’re waiting for the wet time to pass.

    fun fact! the opacity of audio effects is instead described by a scale from wet to dry, with full wet being 100% “opacity” and dry being 0% “opacity”

      That’s nice and all, but I have no idea what either “wet” or “opaque” mean in relation to sound =(

        sound effects, or more properly audio effects - are things like pitch shifts or reverb, you apply them onto a clip and they modify how said clip sounds. If you later decide you added too much of say reverb you can always lower the wetness of that effect, in the same way you’d see a layer of a picture halfway through you can now hear the sound effect halfway through!

    Had to explain how iso alcohol is a poor disinfectant earlier today and I’m still mad about it.

          ELI5 answer is 90% alcohol dries out the bacteria too fast and it converts into a bacterial spore with a hard shell that protects its insides.

          70% alcohol gives it time to penetrate the cell wall and “dissolve” the insides of the bacteria, either killing it or rendering it non infective.

          From what I understand, the water helps “penetrate” the cell walls of bacteria and deliver the lethal dose of alcohol. Take out more water and it’s unable to penetrate and murder things as efficiently.

            Alcohol and water are both polar and form hydrogen bonds, but of differing strength. You want those bonds to switch, which creates conformational changes and rips the structure of proteins apart. If you just replace all the bonds with alcohol you’ll develop a new, although denatured, stable configuration which can keep the cell wall intact. Instead you want to keep developing new stresses on it until it breaks. Neither can really penetrate the phospholipid membrane of the cell because it’s nonpolar, but those conformational changes create big holes where the surface proteins are.

          Iirc, the higher water content keeps the alcohol from evaporating off as fast, keeping it in contact with the surface for a longer period of time.
