After teasing the world for months, Lexus shows off its fully functioning HOVERBOARD. Yes, it still doesn't move on every surface but it sure is going to give you goose-bumps if you get to ride it!

Now let's look at the science behind it:  Lexus hoverboard works on the very same principle of the magnetic levitation train work. So riding it would basically be like straddling a maglev train. You will see steam coming off both sides. That's liquid nitrogen, cooling the superconductors to -321 degrees Fahrenheit, the temperature at which they become superconducting.

Here's a video showing the development of the hoverboard from day 1!
