    Just heat up the lid a little bit.(if the lid is metal)

    You can use hot water, although I have found rolling the lid on my electric stove for 10-20 seconds works better because then it’s not wet after.

      I wonder if they actually use the same trick to actually put the lid on as-well to create as-tight of a seal as possible

        I assume all parts are heated first because that’s how you ensure it’s sterile. It also serves to make a slight vacuum once cooled which will keep everything sealed.

      Slide the tip of a dull knife under the side of the lid, then apply a little leverage so air can get in. Even easier, and wastes no power
