Interesting fact: A lightning bolt contains plasma with mass, but its overall weight is extremely small.
The answer: A typical lightning bolt weighs only a few grams due to the ionized air plasma it contains.
Lightning is a sudden electrostatic discharge that ionizes air, creating plasma. This plasma consists of charged particles with mass, but the total amount of ionized air in a lightning bolt is very small. While the energy released is immense, the actual mass of the lightning bolt's plasma is negligible, usually just a few grams. This explains why lightning can be so powerful yet have almost no weight.
