A few years ago I came on this board after Mattel released a prop replica. I suggested maybe a real Hoverboard will be invented. I was told in no uncertain terms, that I was talking science fiction and this was a Physics forum. With Hendo announcing today a 2.0 version of their hoverboard. How did it go for being science fiction to fact. What advancements were made? Yeah I know it wont work outside etc etc. But to get to this point this quickly seems pretty amazing.
