The key part of your engine
The key part of your engine is one of the very smallest, namely the bearings.
These tiny little things come as part and parcel of just about every piece of machinery that we use these days so the things are produced by the million right around the world and oodles of different sizes too of course. Although seemingly trivial these little items are naturally essential to keep the various moving parts actually moving: you definitely notice them if they’ve rusted up for sure.
And, of course, they’re used in those neat little puzzles for the kids.
