Based on the similarity of the device in the viral video to prototypes designed by a company named Omni Hoverboards, Snopes concludes that the video is genuine.
In 2017, for example, an official delivered the game ball in a Portuguese soccer match using an on an Omni Hoverboard:
Omni Hoverboard's website also highlights their product's capabilities above a pond in this promotional video:
The Omni Hoverboard is not yet available to the general public. Alexandru Duru and Philippe Maalouf, the co-founders of Omni Hoverboards, told TMZ that the company is "very close" to bringing their product to market.
"We are told pricing is still a work in progress, but the 10-propellor model is expected to fetch around $36K," TMZ reported, adding that the company is interested in selling "an 8-propellor model that could retail for around $27K."
Because the video shows a device that appears to be an Omni Hoverboard, and because that product is real and capable of performing the feats shown in the video, we conclude the video is authentic.
