When water is boiling, where do the air bubbles come from?

Your question is actually valid - cold water dissolves a lot of air, and heating drives it out.

But most of the gas in those bubbles is going to be water vapour.

Thank you buddy. I tried to zap you for such a fantastic answer but couldn't. Drop me an invoice for 420 SATs please.

I don't understand the answer and for my sanity's sake I'm about to use a relatively vast amount of precious time to figure out why hot make bubble. An ELI5 would be much appreciated, prem
