Crowd-funded Lego car powered by air

An air-powered car built of Lego, that can reach a top speed of around 20km/h (12mph) has hit the roads of Melbourne.

It was built by an Australian entrepreneur and a Romanian technologist who used more than 500,000 pieces of Lego to complete the car.
The crowd-funded project began with a tweet asking people to invest in an "awesome" start-up.
Four air-powered engines and 256 pistons, all built of Lego bricks, enable the car to move.
Everything bar the wheels is made from Lego.

 "It doesn't look too comfortable though, and I wouldn't want to drive it very far. Or into anything by accident. Using Stickle Bricks in the crumple zones would have made for much better crash performance,"
