random question about superheated water

[futureman 22440]

what’s going on here? it’s an induction stove on high and that pan is hotter than the sun. shortly after this video I actually poured some oil in there and it immediately turned black and burned. so how is this little ball of water not boiling? from what I remember in school for water to stay liquid over bp it needs to be under high pressure, no?

You're observing the Leidenfrost effect! The water IS boiling, but only a thin layer immediately touching the pan that actually insulates the water drop from more heat.
