crack the secrets of levitation in order to purchase a bona fide hoverboard? Look, life's short -- why not take matters into your own hands? A genuine wooden Mattel hoverboard used by Michael J. Fox (or Marty McFly, as we prefer to call him) in Back to the Future II and III is up for auction, though the barrier to entry is rather substantial. Of course, this is considered the "best example of all wood hoverboards to have survived the rigors of filming," but whether or not it's worth the $30,000+ asking price is entirely up to you.
