Wow!
I actually remember seeing those little toy steam-engines. I believe there's a variation called the "Donkey engine".
It's a boiler, smokestack, furnace and a piston that attaches to a big flywheel. And it was supposed to teach you how steam-engines worked.
When I was 11 years old, our Year 5 teacher brought one of those machines into our classroom. He showed us how it worked. He filled up the boiler with water and then he lit a fire underneath it with little blocks of fuel (in retrospect, it was probably solid lumps of paraffin wax). He kept tapping the engine with his finger and eventually the machine built up enough pressure for the wheel and piston to start moving on their own.
After that, he told us all to get out some LEGO. We had to build little machines out of lego. And when we were done, we would give them to him. And he would use a rubber band to hook the wheels of our machines up to the steam-engine's flywheel. And we got to see our machines move.
Boy that was fun...
Here we are:
Another model:
Single-cylinder stationery steam-powered 'donkey engine'.
That's what our teacher brought into class. Boy it was fun to watch...
