That sounds bad

Great video. Just so y'all don't think I'm mad, I am not heating my water that hot to warm up breastmilk. It just starts boiling a bit. Rapidly, but nothing explosive. :)
ChadTower:
There isn't much more to heat than boiling, bro. A couple degrees more and it's not water anymore. :)
shmokes:
Actually, yes there is. That's what superheating does. Under normal conditions the water will turn to steam at the boiling point, but without imperfections or particles to encourage the first bubble the water will continue to increase in temperature without boiling. I imagine, but don't really know too much about it, that to get really really hot you have to have controlled conditions. I don't know how hot a microwave can get tap water in a glass container (I'd think distilled water could get MUCH hotter). But I do know that my water never boils like the stuff in the video when I drop in the breast milk.
ChadTower:
Water has to be under some sort of pressure in order to stay liquid at a temp much higher than 100c. Pressure keeps the molecules packed even though they are trying to space out and convert to gas. I am not all that convinced the water is superheated nearly as much as it is simply not expelling the potential energy in the bottom of the container. Given more time, it would do that without trouble, so maybe it's just that the water in a microwave gets raised to 100c so fast that it doesn't have a chance to expel the gas being formed in millions of molecular sized spots. Then, when you shake the container, or add something to it, poof the gas molecules start to meet and shoot upwards as heat does.
It has to conform to basic physics, which is to say in order to heat a liquid above its boiling temperature you have to apply pressure in order to keep it from becoming gas.
