Sorry to burst your high-flying dreams, but Funny or Die is behind HUVr, the mysterious tech company claiming to have invented the first hoverboard.

The truth behind this massive viral campaign came out after a costume designer who worked on the shoot posted the experience on her online resume, which has now been removed.

The clip from HUVr's YouTube channel appeared online on Tuesday. The clip claims to show off a real-life version of Back To The Future II's fictional hoverboard. The video features a slew of high-flying celebrity endorsers, including Christopher Lloyd, Tony Hawk and Moby.

HUVr also released a video featuring actor Billy Zane explaining the technology behind the fake hoverboard. The company's website claims its team consists of "materials science, electricity & magnetism experts who've solved an important part of one of science's mysteries: the key to antigravity."

Alas, despite the impressive viral campaign, the only place you'll find hoverboards for now is on screen or in your dreams.
