How do lava experiments work?

Lava Lamps are fun to create and they are very simplistic, meant for any age group .  The only ingredients you need is Water, Vegetable oil, salt, food coloring and a cool glass jar.  You are probably wondering, how in the world does this work! Well, Oil is less dense than water so it is able to float above the water.  When you add the salt, the salt crabs part of the oil and drags it to the bottom of the jar because it is denser than the water.  The Salt will then start to break down and dissolve.
