Its name comes from the Greek word Αἴολος and latin word pila, it means "The ball of Aeolus." Aeolus is the ancient Greek god of air and wind.
How it worksEdit
A ball is free to rotate on a hinge, 2 or 4 L-shaped nozzles stick out of the ball, the ball is to be filled with water, and a source of heat (such as fire) is placed underneath the ball, as the water gets hot, it turns to steam that forces its way out of the nozzles, pushing the ball around, therefore, the aeolipile is a kind of reaction turbine, and the nozzles use a similar principle to rockets.
No one really knows if the aeolipile was used for anything in ancient times. In modern times, they are used to teach physics and how steam engines work.
