Substance with similar properties to water.
Just wondering whether anyone knows of any substances which share the property of water of having the solid phase being less dense than the liquid.
Never accept that which can be changed.

Just offhand, I think the only other such substance may be hydrogen peroxide. Also, the expansion of ice on freezing does not apply when it is under
high pressure; there are about 12 different phases of ice which occur under conditions of varying temperature and pressure.
