Boiling water with Ice (diode.zone)

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.

Do it! it is easy to do at home! Just wear some gloves and safety glasses, those jars can easily shatter during the heating process if you use too hot of a heat source. I recommend a glass top electric stove, or put some kind of metal plate between your jar and the burner to help spread out the heat. Once you seal the jar, take it off the heat right away, so it doesn't build pressure. I boiled mine for a few minutes before sealing to try and get some of the devolved gasses out, and lightly set the lid on top to help the steam push out all the air.
