Growing up I always played with Legos, but I never even imagined building something this awesome. Some self-taught super genius from Romania has built a full-size Lego car that runs completely on air. It's pretty cool.

Even the engine is made from Legos and includes a total of 256 pistons. All together the project used over 500,000 pieces. The car can even reach speeds of almost 20 mph, but obviously they try to go as slow as they can to reduce the risk of a Lego explosion.
