CoolDoes that mean superheated water is possible? Or only under pressure?
I like the idea of dropping a grain of sand into superheated water and watching evaporate instantly in a poof of steam :)
I love science me

Oh yes.In fact you have to be careful when heating water in a microwave, if you're very unlucky it can become superheated. Then when you stick a spoon in to stir it, it'll boil explosively.

Oh hell yeah! :DNucleation does pop up in all sorts of places, I'm studying Materials Science and it always seems to be the explanation for something. The best demonstration we had involved champagne, and how to pour it without getting too much foam on top. (And then drink it of course!)

This should work. And before superheat point.Might need a really pure, and free from stray dust, atmosphere though.
Adding pasta to really hot water gets damn close to full evaporation.
