After a lot of crazy challenges such as planking, cinnamon eating, ice bucket pouring, mannequin standing and bottle flipping, another unusual challenge has gone viral.

A Texas cheerleader Ariel Olivar shared a video on Twitter, where she can be seen expertly pretending to pat and then step over an invisible box on the sideline of a football game. The video got nearly 220,000 likes and over 112,000 retweets in the two days since it was posted.

Pretend you’re putting a foot on a box and then hop over it with the other foot. It requires some good kinesthetic sense to keep the raised leg in the same position while you lift the jumping foot higher.

Many internet users have been left dazed and confused wondering how the trick actually works, some even tried the trick. “The video was my third time trying it. It's hard to explain, I just keep the leg in the same exact spot,” Olivar told The Houston Chronicle.
