What is the Invisible Box Challenge?

The magic of being able to step over air has fascinated the internet. Dubbed the "invisible box challenge," the objective is to convincingly step over an imaginary box. Many celebrities have tried the challenge, some, like Justin Bieber are surprisingly successful, while others, *cough cough Logan Paul* failed miserably. The trend started with a high school cheerleader, Ariel, posted a video of her stepping over an invisible box. Viewers were baffled and eager to try the challenge themselves, and the craze has since spread throughout the internet.
