Science Guy Steve Spangler explains how you can layer liquids in this easy experiment that explores density.

A hidden feature of water, long submerged, has finally been brought to the surface. New experiments have revealed supercooled water’s critical point — a specific pressure and temperature at which two ...

Create a colorful tower of liquids that stack on top of each other based on their densities. This experiment demonstrates how different liquids have different densities and why some liquids float ...
