The steam rotating ball was the earliest steam engine. The steam ball, also known as the Aeolipile, was invented in the 1st century AD by the ancient Greek mathematician Hero of Alexandria. It was the prototype of the steam engine, which used the reaction force of a jet of steam to drive an object to rotate. Prepare yourself for an immersive experience that unveils the marvels of this groundbreaking revolution and its profound influence on the development of human ingenuity.
Visual and Tactile Engagement:
A hollow, spherical vessel adorned with two opposing sets of nozzles, connected to a source of heat via a sealed pipe. As the water within the sphere is heated, steam is generated, which escapes through the nozzles, creating a reactive force that causes the sphere to rotate on its axis. This hands-on encounter will allow you to tangibly connect with the transformative power of steam technology in its nascent form.
