British engineers – inspired by an 5 year old boy – have made a six foot long replica of a jet engine made entirely from Lego.

The story behind the birth of the replica (of a Trent1000 Rolls Royce jet engine, if you want to know the exact type) is pretty adorable: a five year old boy had made a much smaller one with his Dad and his Dad had sent the smaller engine in to Rolls Royce on a lark. When brand manager Sarah Martin saw the tiny Lego engine she decided to task a team of engineers to make a life size Lego jet engine. It took a team of four engineers 8 weeks to complete the massive 6ft Lego jet engine, made out of 160 separate engine components and 152,455 standard pieces of Lego.

Here’s the one the 5 year old and his Dad made:
