WATCH | How to build a miniature car engine

If you have a fascination with things mechanical, you're sure to be delighted by this video which shows the assembly of a miniature four-cylinder engine.

Uploaded to Facebook by Maxpower Motor Sports, it's mesmerising to watch this metal hobby kit coming to life as all its mini components - pistons, valves, crankshaft et al - are bolted together.

The end result is a working model that shows how the various components of an engine interact with one another, with cutaways in the engine block showing the tiny pistons at work.

Watch and enjoy!
