This is the moment a man disappears behind a so-called invisibility cloak - and he says he wants to sell the technology to the military.
The video shared by police chief Chen Shiqu in China went viral and amazed more than 20 million viewers.
It shows him walk through a garden before he drapes himself in the garment and vanishes behind it.
The footage shows the material seemlessly camouflage him into the background of the trees and other foliage.
But experts quickly branded it as a hoax, saying it was done with the trickery of software found on the average home computer.
Chen Shiqu, deputy head of Criminal Investigation Department at Ministry of Public Security, shared the video that was seen by ore than 20 million viewers on the Chinese social media platform Weibo.
He wrote: "Quantum cloak is made of quantum stealth material into clothing, by reflecting light waves around the wearer, it can make people wearing such clothes be 'invisible'.
"The technology can be used in the military - soldiers who would like to wear 'stealth military uniform'."
Viewers were amazed and hundreds left comments on the page where the video was shared.
Yang Yang said: "Wow, Harry Potter's clothes", while Rosamond remarked: "Good stuff."
But the producer of Quantum Video production company said there was no such thing as an invisibility cloak.
Zhu Zhensong told the Liberation Daily: "Softwares such as Adobe's After Effects, Nuke or Blackmagic Fusion can edit the background and blend the object into it. The effect has previously seen in a lot of action movies."
