I just realized gallium would be liquid at "room temperature" where I'm at...

Well, sort of. Gallium melts at 30C, which is 86F. My room needs to be minimum 80 degrees. And the thing is, my room is often up to 10 degrees cooler or warmer than the AC setting, due to some effect I still don't understand or even know about. It's very well possible gallium could be a liquid at my idea of a "room temperature" and would certainly be a liquid outside... >.>
