Unveiled at the Farnborough International Airshow in England, the Lego engine uses 152,455 bricks for an overall size of 4.9 feet long and 6.5 feet wide. Together, all of those Legos stack up to an astounding 676 pounds.
The Lego jet engine's blades rotate just like the real deal. The high-pressure turbine blades inside the actual engine rotate at 13,500rpm, with their tips reaching 1,200 mph -- twice the speed of sound.
The Lego jet engine took four people eight weeks to complete. They built and joined together 160 separate engine components to replicate a real jet engine.
