There's a video of one of these constructions where the last gear is bolted to a wall or something.

Might be think of “machine with concrete” https://m.youtube.com/watch?v=5q-BH-tvxEg

I feel like doing the project in Lagos is going to confuse people but when you put the final gear bedded into concrete that sort of gets the point across

Yep, that's exactly it, thanks!

And as per that top voted comment:

The question of whether the last gear will break the concrete is moot. The gears themselves will erode away to nothing before they get a chance to apply much torque to the final gear.

I think that the same argument can be made to this Lego demo as well ;-)
