In the 1989 movie Back to the Future 2, Marty McFly and Emmett "Doc" Brown travel forward in time to the year 2015. 2015 is a wild, futuristic place, and probably the most memorable part is they have hoverboards! Like skateboards with no wheels. Now Christopher Lloyd, who played Brown, is here to present the hoverboard a year early.
So, yeah, this is no more real than the Back to the Future trilogy. It does look fun though.
