This is a jar full of only water (liquid and vapor). It boils at any temperature when you apply something cold enough to the top, like ice.

I put water in a jar and sealed it while it was boiling, and now it boils at any temperature. Super fun demo to try.

Hmm. I wonder if you could make a higher-quality vacuum this way by adding a getter. You'd think it would still be safe-ish with reactive metals because bulk liquid water never needs to be anywhere near the chamber (air will remove heat too, just somewhat slower).
