The Match and Magnet Mystery Explained
Description
Discover the scientific secret that allows a magnet to attract the head of a burnt match, even though a regular match is non-magnetic. This fascinating phenomenon occurs due to a chemical change in the iron compounds found within the match head during combustion. This process transforms them into paramagnetic materials, allowing them to react to a strong magnetic field.

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
