This video shows the moment a tornado-like swirl blew through a pile of leaves, causing them to lift up into the air and move in almost perfect circles.

The filmer, who shot this in Bukit Panjang, Singapore, said she captured this on the windy afternoon of October 6.

"I was walking towards the entrance of a mall called “Junction 10” and chanced upon this view," she said. "The leaves illustrated the direction of the wind in a spiral motion."
