Engine blades

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.

Looking down the length

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.

Hot stuff

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