The Internet loves its physical challenges. Two that immediately spring to mind are the revolting cinnamon challenge and the planking fad which had us all on the floor in a state of wooden piss-taking.
Now the latest one is the 'invisible box' move where people apparently walk in mid-air by stepping onto an 'invisible box' with one foot and jumping over it with the other.
The current boom dates back to August of this year, when the Anderson University American football player Dontez Hines uploaded a video on Twitter of him patting down his invisible box, stepping on it and landing on the other side like a boss.
The video quickly went viral and, of course, many others have uploaded their own attempt at scaling their invisible obstacle - to variable success.
The most successful of these was the Manvel High School cheerleader Ariel, who had a go at the move and blew people on social media away.
Like Dontez, Ariel nailed the trick, and has been rewarded with a tweet that has now been re-tweeted over 100,000 times.
However incredible and movie-like it looks, the 'invisible box' trick is actually real, which left many Internet users wondering how the fuck it works and where it came from.
The move seems to have been documented as early as August 2014 when Mexican dancer Macros Grados was filmed completing it in a video uploaded to YouTube.
Grados' performance has now been viewed over 890,000 times, so many people must have taken their mime act from him.
The basis of the stunt seems to be hopping forward with one foot while keeping your 'stepping' foot fixed in mid-air - easier said than done.
The man who supercharged the fad doesn't seem to know much about how he did it either, as Hines told Men's Health that anyone could perform the move with a little bit of graft.
"It is really nothing special," Hines said. "I just imagined that there was a box and stepped on it." Cheers, mate. Really helping me with my technique there.
Men's Health's fitness editor, Ebenezer Samuel, was more helpful, explaining that the move needs a "little extra strength and stability" to pull off but is basically a one-legged hop forward with a lot of elevation.
"All his hip stabilizers on the right side are firing on overtime to hold that hip in position," Samuel said. "You'll notice his body rotates toward the leg on the step as well; there's a ton of oblique and ab stability maintaining that position.
"Very explosive hip flexor, abdominal and glute strength is what is driving the leg up and over the box."
Sounds doable to me. Now, I'm just off to fall on my arse trying to pull it off.
