The Physics of Inverting a Cup Without Spilling Water
Description
Discover how the laws of physics and air pressure make it possible to perform surprising experiments using only a glass of water and a simple piece of paper. This video demonstrates two different methods for turning a full glass upside down without spilling a drop, revealing the forces acting on the liquid to hold it in place against the pull of gravity. This is an easy-to-perform home experiment that illustrates the fundamental scientific principles of atmospheric pressure.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
