A Fountain in a Bottle
Description
A demonstration of creating a fountain inside a closed bottle, illustrating the physical principles of air pressure. By utilizing temperature changes or water injection, a pressure differential is created, causing water to flow powerfully upward through a straw. A simple yet impressive scientific experiment that can be conducted with everyday household materials to understand how gas pressure influences liquids.

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
