Insanely detailed Lego reproduction
The team of four people from Rolls-Royce spent eight weeks building a roughly half scale replica of one of the company's Trent 1000 jet engines. That is one of the engines that will be used on the Boeing 787 Dreamliner. The project used 152,455 Lego blocks.
All those blocks weighed 677 pounds and when finished the jet engine replica measures 6.56 feet long. That's roughly half the size of the actual engine, which weighs in at 1.25 tons. The Lego model accurately represents every part of the engine from the massive fan that slurps air into the combustion chambers.
