A man known as Mr Hoverboard has successfully constructed a DIY hover board out of leaf blowers and proven its functionality at an Austin, Texas skate park. The video below shows him floating around in public surrounded by curious onlookers and then he even lets the bystanders take it for a spin.
Because the design is pretty simple, Mr Hoverboard has posted the instructions for free on his website. I would imagine that anyone could make one for just a few hundred dollars. Eat your heart out Tony Hawk.
