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.

    Thank you for the answer. I’m tempted to try it, but I’m guessing this is not something you can easily do at home.
