How a girl can defeat two adults at tug of war
Description
Discover the physics secret that allows a young girl to defeat two strong adults in a game of tug-of-war using a makeshift pulley. The video demonstrates how wrapping a rope around poles creates immense mechanical advantage, while explaining the relationship between frictional force and the number of coils, and how this interaction affects the distribution of power.

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
