Did you or your kids get Legos for Christmas? Well, just in case you’ve got an extra 500,000 lying around, you can try your hand at building a pretty sweet hot rod that runs on air. That’s what Steve Sammartino, an Australian entrepreneur, and Raul Oaida, a Romanian tech genius, have done. Dubbed the Super Awesome Micro Project, some components of the car like the tires and some load-bearing elements aren’t Lego, but as you’ll see in the video below, the car is actually drivable and is powered by an all-Lego engine that creates air power through four orbital engines and 256 pistons. The car’s top speed is only about 12-19 miles per hour, but then again how many of your Lego creations can you take for a spin? Check it out below.
