Eli5 what would happen if you had water in a completely sealed container and brought it past boiling temp

Question

Would it just turn into a pressurized container full of steam? Would the water stay water but just like, really hot?

Probably my favorite experiment of all time from them.

As the water gets hotter, it will be more difficult to contain the steam. Unless you have a completely unbreakable container…well boom!
