    I use my microwave for so much more shit.

    But I constantly hear some bullshit myths about it, too. Like superheating water so it boils over when you grab the cup. If you’ve ever seen this happen IRL, you know it doesn’t boil so violently it splashes outside of the container. It’s also incredibly easy to prevent by just using a toothpick or putting something in the water so it has nucleation points.

      Superheating water can absolutely fuck you up. Steam is like 700 times less dense than water so what happens is a steam bubble forms inside the superheated water at a nucleation point and explodes the water out of the cup since what used to take up 1ml of space now takes 700ml of space.

      It might not splash out every time but it happens often enough to make superheating water extremely dangerous.

      I have for sure experienced the explosive boiling over of superheated water, but like a couple times in my life and I’m an old guy. It’s crazy when it happens though. The water looks like it didn’t get to the boiling point, but when you disturb it, it starts insanely boiling over. Got boiling water on my hand, but not badly burned.
