A Silicon Valley company has fulfilled everyone's childhood dream by developing a real-life hoverboard like the one Marty McFly famously used to get around in "Back to the Future Part II."

The tiny catch? Because the board works through the magnetic principle that like poles repel one another, it only flies while over conductive surfaces such as aluminum or copper, Re/code reported.

Available for a $10,000 pledge, the Hendo Hoverboard has already raised more than $232,000 through Kickstarter crowdfunding. With 53 days to go, it's safe to say the project will likely be fully funded at $250,000 before the deadline.

Jill Avery Henderon and Greg Henderson, the husband and wife team who founded Arx Pax, have even bigger dreams for the hoverboard's technology.

"It used to be a fictional device and now we have it," Jill Avery Henderson told Re/code. "The applications are limitless when you start thinking of it as being as fundamental as the wheel."

The startup has a team of 19 people and was founded with the couple's own savings.

As an architect, Greg Henderson has been working to find ways to shield buildings from earthquakes and rising sea levels. But before the technology is used for flying skyscrapers, the Hendersons believe it can be an option to move people and materials.

"The magic behind the hoverboard lies in its four disc-shaped hover engines," said the project's Kickstarter description. "These create a special magnetic field which literally pushes against itself, generating the lift which levitates our board off the ground."

According to the Kickstarter page, the Hendo Hoverboard is now in its 18th prototype and does indeed allow its rider to move on air.
