Check out this incredible fully functional hover-board

A Frenchman whose hoverboard invention is being considered by the US Army for usage by combat soldiers was spotted flying his super-fast device over a lake in Arizona.
Franky Zapata, a former professional jet ski driver, was seen flying his Flyboard Air hoverboard over Lake Havasu earlier this month.
In footage of the flight, Zapata is seen hovering dozens of feet above the Lake Havasu beach as onlookers watched the amazing flight.
Wearing a protective helmet and flight suit, he zooms past palm trees and over water and sand during the minute-long video.
Upon finishing the flight, Zapata lands on a nearby platform and is helped down by a nearby onlooker.
It's unclear how Zapata takes off on his hoverboard, as the video starts after his is in the air.
There are also no specific details on how Zapata is controlling the Flyboard or what exactly is powering it.
But Zapata spent several days in Lake Havasu City testing out his new board during air shows in Sara Park and on a nearby beach, according to Havasu News.
Residents of the city came out to watch him soar through the air and do tricks on his futuristic board.
The Flyboard Air allows users to fly untethered through the sky to an incredible height of 10,000ft (3,048m), which is almost seven times that of the Empire State Building.
The 37-year-old's original Water Flyboards are popular with the likes of Justin Bieber and Kylie Jenner - but his latest invention puts Marty McFly's hoverboard to shame.
The device uses an 'Independent Propulsion Unit' to fly for about ten minutes and has a top speed of 93mph (150 km/h), Zapata Racing claims.
Zapata is working with the US Army on uses for the Flyboard Air, but details of their collaboration are classified.
The former jet skier did say, however, that the plans are to make the boards available to combat soldiers.
