A video of a water stream in Canada quickly disappearing beneath ice has gone viral on social media, leaving people amazed.

The video of the rare phenomenon, shared by Brad Atchison on Twitter on Wednesday, shows the stream disappearing as the snow covers the area.

"An example of rarely seen Frazil Ice from Shannon Falls in Squamish, BC yesterday morning. The stream disappears instantly before your eyes," Atchison captioned the video.

Confirming the video was not fake, he wrote, "For my followers in here. I zoomed the original video in a tiny bit. A very few people thought it was fake and just reversed. Absolutely not! I would never have posted it if it was."

Jessie Uppal, a meteorologist at The Weather Network, called it a rare phenomenon "that occurs when water bodies experience extremely cold temperatures."

"The air temperature surrounding these streams is well below freezing and much colder in comparison to the water. These small bodies of water are supercooled, meaning the temperature of the water drops below its normal freezing point, but remains as a liquid," Uppal told The Weather Network.

"This is where we start to see the formation of ice crystals on the surface of the water. These ice crystals are somewhat soft and have little structure to them. Since the flow of water is constant and turbulent, the soft ice crystals that do form are not able to completely freeze solid. With less turbulent streams, more ice is able to accumulate quicker, which created the illusion of a disappearing river," Uppal added.

Meanwhile, the video has since gone viral on Twitter, garnering over 91,000 views. Several people took to the comments sections to share their views.

"That is so cool. You would almost think it's a time lapse, but you can tell by the movement of the camera that it's definitely not. I've never seen ice form so quickly," one person wrote.

"I’ve never heard of this, let alone see it! Amazing! Thanks for sharing," another person commented.

Another user wrote, "This may be the coolest thing I have ever seen."
