10 июн 1752 г. - Benjamin Franklin Invents the Lightning Rod
Описание:
The Lightning Rod serves as protection against lightning strikes for houses and ships. It safely moves lighting strikes from hitting the structure to the ground. Benjamin found out about this by attaching a Leyden jar to a kite so then he can see the lighting's natural way to move.Добавлено на ленту времени:
