  • Damn, made me chuckle

    Anyways, going by

    , i have had multiple people (2, which is not a lot but it’s weird it happened more then once) say that they couldnt solder just to discover that they were using their soldering iron wrong.

    When you press the solder against the iron’s tip, it should get wicked by the tip, and remain there until you press it on some wire/component leads.

    If the solder beads up and slips away from the iron, or beads up and forms a blob at the end of the solder wire, it’s oxidised and you probably need to get a new tip. It needs to be shiny and metallic.

    The tip needs to be regularely cleaned while soldering by brushing it on a wet sponge, and never let the iron cool down without some solder on the tip to prevent oxidation.

  • when it spontaneously degrades, yes, it turns into tame water and healthy oxygen, but when it touches organic matter (your skin, tongue, mouth, etc) the oxygen directly reacts with the carbon atoms to make CO2, effectively “burning” away your tissues very slowly.

    Usually, you don’t notice that because you use store-bought 3% peroxide, but chemists regularly use the much more powerful 35% peroxide, which gives you nasty burns

    also, fun fact, some cells produce hydrogen peroxide as a waste product, so nature has evolved the catalase enzyme to break it down, and that’s why you see bubbling when using it on a scar but not on skin, because that enzyme is only inside you and your blood
