Nobody has made a Treasure Planet hoverboard yet.
There are however attempts to making a workable hoverboard one
is an air cushioned hoverboards with leaf blowers, early attempts
to make the ducted fan hoverboard like the Hiller platform in 1955,
and there's also hoverboard crane props that allowed people to
hover in Star Wars 1, 4, 5, 6, Back to the Future 2, The Funny or
Die video Hoverboard Belief with Tony Hawks and Christopher Lloyd
which was then photoshop to make people believe. There's also been
a maglev hoverboard made by the Hendo Hoverboard team.
I'm sorry if my answer disappointed you hoverboard fans,
hopefully it will get made one day.
