An EGG-citing Density Demonstration

We used the power of salinity to suspend an egg in the middle of a glass container!  The more dense salt water remained at the bottom of the container.  The less dense pure water stayed on top.  The egg (being more dense than the pure water and less dense than the salt water) floated between the two!  Deep ocean currents form when salt water sinks to the bottom of the ocean, causing streams of water to occur well below the surface.
