A moving replica of a jet engine has been made out of thousands of Lego bricks.
The half-size replica of the Rolls-Royce Trent 1000 engine has been created to inspire young people to pursue careers in engineering.
It was made by professional Lego builders Bright Bricks, with advice from a team of graduates and apprentices from Rolls-Royce.
Staff at Rolls-Royce in Derby have been inspecting the engine this week.
The inspiration for the model came from a five-year-old boy.
Rolls-Royce brand manager Sarah Martin said: "He'd sat down and built a little engine out of Lego with his father, sent it in to me and that was the sort of seed of the idea."
The engine is normally used to power the Boeing 787 Dreamliner aircraft, and the Lego version is more than 6ft 6in (2m) long.
More than 160 separate engine components were built using 152,455 Lego bricks, then joined together to replicate a real jet engine.
It took four people eight weeks to complete.
Ben Russell, a higher technical apprentice at Rolls-Royce, said: "This has been such an exciting project to be a part of and something I never imagined I'd get to do.
"I hope our Lego engine will show others how exciting a career in engineering can be."
