minus-squaremozz@mbin.grits.devlinkfedilinkarrow-up20arrow-down1·10 months agoYou know the little oily colorful sheen on the top of a cup of coffee? At one point just at random I made a pot of coffee from a jug of distilled water I had, instead of the filtered tap water. It had no little colorful sheen. I have no idea if it’s a big deal or not, but it made me legitimately concerned.
