How to relight a candle from its smoke
Description
Discover the science behind the spectacular trick that allows you to relight a candle without ever touching the wick. When a candle is extinguished, the rising smoke contains flammable wax vapors that act as a fuel bridge, carrying the flame from your lighter back down to the candle. This experiment demonstrates the various stages of wax combustion and the fascinating relationship between states of matter and the burning process.

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
