Ball lightning poses a serious danger to people due to the possibility of explosion, electric shock and burning of objects. Physicists from Moscow State University conducted experiments to understand what this phenomenon consists of.
Researchers suggest that ball lightning is clouds of evaporated earth surrounded by a hard crust after a lightning strike. Such balls can burst due to pressure inside the shell, causing dangerous consequences.
In addition, ball lightning contains hot gas, which can cause surrounding objects to burn and cause a fire. These discoveries confirm the statements of people who encountered this phenomenon in practice.
