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.

According to Rolls-Royce, temperatures inside the hottest parts of the actual engine are about half as hot as the surface of the sun.
