Water Boiling at Room Temperatures, Under a Vacuum

If the water pressure goes up, as in the bottom of the Mariana Trench; where the pressure is about 7.5 tons per square inch, then the boiling and freezing points of the water goes up, If, however, the atmospheric pressure goes down, as on the top of Mount Everest, then the boiling and freezing points of the water goes down. In the case of the top of Mount Everest, the boiling point of pure water is about 72 C. The experiment shows how water can boil at quite low temperatures, under a vacuum.

Yes, ice at 0 degrees may turn into water and boil at "room temperature"; the main restriction being that one can only get a vacuum of the magnitude of an atmosphere; which in Imperial units is about 14.7 psi & in SI(metric) units is about 1 bar. It may be worth trying this experiment out under laboratory conditions.

Are there any items that are solid at room temperature that would become a liquid or gas under a, feasible at home, vacuum? I am no scientist, at least yet, so it has bothered me that I haven't been able to find the answer. I'm thinking something not absolutely fucking ridiculous, so something that I could actually test with that isn't grievously expensive, and at a vacuum of no less than .2 atmospheres. Thank you to anyone that answers!!! :)

I think the water just gets sucked in the vacuum...
