Water without anything in it doesn't boil over
Until it suddenly does, and violently if actually superheated.
It's not becoming super heated in an open pot.
Thankfully
You can't superheat water in a pot on a stove. I don't think you can at all with a conventional stove.
You can do it with a conventional stove, you just need defect free pots. Also the problem is not nearly as pronounced as it is in the glass tube thingy in labs, because a pot is much wider, so there is not such a dramatic eruption.
pressure cooker with the valve soldered shut
That’s what the impurities are for
Tbh it doesn't even boil at all, like trees that make no noise when falling if nobody is looking, water doesn't boil either. It requires conscious observation, similar to photons acting as a wave until observed which then they are particles.
