know of any small scale Rankine cycle engines that are classroom safe for a presentation?

have a school presentation on a thermodynamic process and would like to present a Rankine Cycle but i havent been able to find one that i can build and run within a classroom

just looking for a design or directions, even a video that i can use to build one

In a school environment your better off driving a steam engine with compressed air. A car tire would do or an aquarium pump is often used.

Stirling cycle engines are safer.
Its a steam engine.
