Have you heard of the "Invisible Box Challenge?" You can see it in action in this video of a cheerleader doing it that went viral.

While Sarah was doubtful whether the video itself was fake (hello, Jimmy Kimmel), Eric, ever the optimist, was eager to see if you could pull it off.

BuzzFeed
This was what Eric's first attempt looked like.
BuzzFeed
"That was pathetic. Do it again."
And this is what Sarah's first grand attempt at the invisible box challenge looked like.
BuzzFeed
Solid effort.
Okay, but what about their coworkers? Could they pull off this challenge with practically zero notice and absolutely no time to practice?
BuzzFeed
Not bad, not bad.
They even barged into a meeting to see if someone in there could pull it off.
BuzzFeed
So close, but no cigar.
Once it was established they weren't finding any invisible box masters in the building, Sarah and Eric hit the streets of NYC to put people up to the challenge.
BuzzFeed
Nope.
Some weren't bad at all. Like this woman who tried it in the park.
BuzzFeed
Nice one!
Sure, some invisible box steppers were a little shy to try out this challenge at first, but everyone was a great sport.
BuzzFeed
Nothing to be ashamed of, buddy. Maybe just a little more practice?
Once it became clear nobody they had come across actually knew how to do this challenge, they went straight to the source — Ariel the cheerleader!

BuzzFeed
So that video was totally fake, right? Nope. Oh, and get this: It took her two minutes to learn how to do that invisible box trick.
After getting expert advice on his approach from Ariel, Eric was determined to master the invisible box challenge once and for all with intense training!
BuzzFeed
He put in a lot of practice. Like, a lot.
Meanwhile, Sarah opted for a different route. Ssshhh!

BuzzFeed
Yes, that's a green screen.
Just when Eric was ready to throw in the towel on the challenge, something amazing happened. He fucking mastered it!
BuzzFeed
Check him out!
And this is what Sarah's totally made up version of her conquering the invisible box challenge looked like. LOL!
BuzzFeed
Nice try, girl, but that looked way too clean.
Sarah and Eric called Ariel back to show her Eric's new skills, and she was totally impressed.

BuzzFeed
"You accomplished it!"
Immediately after getting the approval of the master herself, Eric hit the streets of NYC to proudly show off his invisible box challenge skills, because, why not?

How ya' like me now?
