How sweet, you built the Millennium Falcon out of Legos. Well, it is nothing compared to this...

The hot rod is the brainchild of Melbourne entrepreneur and marketing guy Steve Sammartino and Raul Oaida, a self-taught teenage technology genius from Romania who Steve met on the internet.

According to the YouTube description, it was built from more than 500,000 pieces, has four orbital engines containing 365 pistons which are powered by air. The black and yellow beast can reach insane speeds of almost 18 mph!

The builders note that the didn't drive that fast in the video for fear of a Lego explosion; you know how painful stepping on one is, getting one lodged in the eye after an explosion would be unbearable!
