8. Hero's Engine

There are commercial science kits of varying complexity.

https://en.wikipedia.org/wiki/Aeolipile

An aeolipile, aeolipyle, or eolipile, from the Greek "αιολουπυλη", also known as a Hero's engine, is a simple, bladeless radial steam turbine which spins when the central water container is heated. Torque is produced by steam jets exiting the turbine. The Greek-Egyptian mathematician and engineer Hero of Alexandria described the device in the 1st century CE, and many sources give him the credit for its invention.[1][2] However, Vitruvius was the first to describe this appliance in his De architectura (ca. 30-20 BCE).[3]

The aeolipile is considered to be the first recorded steam engine or reaction steam turbine, but it is neither a practical source of power nor a direct predecessor of the type of steam engine invented during the Industrial Revolution.[4]
