(USA TODAY) -- The first drivable Lego car is made of 500,000 pieces and runs on air.

The inventors of the Lego car are Australian entrepreneur Steve Sammartino and Romanian Raul Oaida, a self-taught technology guru.
The car - known as the Super Awesome Micro Project - can reach a top speed of 18 mph. It was built in Romania and delivered to a location in the suburbs of Melbourne, Australia, where the car was test-driven, according to the inventors' website.
"We were scared of a Lego explosion, so we drove it slowly," the inventors said on their site.
Even the engine is made of Legos, which has "four orbital engines and a total of 256 pistons," according to the site. Only the tires and some load-bearing elements are not made of the plastic block toys.
The pair met when Sammartino accepted a Skype request from Oaida, who was interested in meeting an astronaut whom Sammartino knew, the Daily Mail reports.
"I'm teaching him about business and he's teaching me a bit about physics. It's a really nice mash-up," Sammartino told the Daily Mail.
The project was crowdfunded through Twitter, starting with a request from Sammartino in February 2012, asking for contributions of $500 to $1,000 from 20 participants. In the end, about 40 people funded the project.
This isn't the team's first Lego project. In 2011, Sammartino and Oaida launched a Lego shuttle in Germany, reaching a maximum altitude of 35,000 meters.
