The Burning Bush Experiment: How to set paper on fire without burning it
Description
Discover how a piece of paper soaked in a mixture of alcohol and water can be set ablaze without being consumed by the flames. This experiment demonstrates the physical principles of heat conduction, evaporation, and combustion temperatures, explaining why the water shields the paper from destruction while the alcohol burns. It is a striking result that illustrates the direct relationship between substance concentration and the ignition point.

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
