Water Pepper and Soap Spinning Top
Description
Discover how the surface tension of water allows you to create a unique spinning top powered by soap and black pepper. This experiment demonstrates the effect of soap as a surfactant, breaking the surface tension and generating the rotational movement of pepper particles across the liquid's surface. It is a simple and fascinating way to understand fundamental physical and chemical principles using common household materials.

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
