Properties of Water
Basilisk Lizard Runs on Water Density: this is a scientific measurement accounting for the number of molecules packed into a set amount of volume. Generally speaking, most gasses are low in density while solids are higher in density. The density of a particular object generally leads to very predictable results. Sometimes, however, density differences can result in some interesting phenomena. First - why does ice float? Shouldn't the solid state of water be more dense and, thus, sink in a glass of water? The air trapped in tap water forces the ice to expand and make the solid form of water less dense! Second - ever heard of underwater lakes and rivers? Wait... that doesn't make sense - underwater lakes and rivers?! Due to different chemical properties, large bodies of liquid (not water!) can form at the bottom of the sea. The underwater "lakes and rivers" are actually large bodies of extremely salty water mixed with hydrogen sulfide. Due to its density (much higher than water), it sinks and forms a new layer!
