The Broomstick Challenge celebs can't get enough of has been debunked by NASA

In case you didn't notice, there's a new craze sweeping the internet.

Dubbed the #BroomstickChallenge, this theory claims that a regular household broom can stand upright without any assistance. But there's a catch. It will only do so on one day of the year: February 10. 

One Twitter user kicked off the challenge, which she claimed came straight from NASA — and surprisingly the theory, er, held up. 

"Okay so NASA said today was the only day a broom can stand up on its own because of the gravitational pull… I didn't believe it at first but OMG!" she said in a video of her broomstick defying gravity. 

The video instantly went viral, racking up 7.8 million videos on Twitter alone, and naturally plebs and celebs alike were reaching for their broomsticks. 

"Now this is a crazy theory. Wow!" said DJ Khaled of his broom standing unassisted. 

Former Fifth Harmony singer Ally Brooke was floored when her broom stood dead-still in her kitchen.

"OH MY GOD?!?! I REBUKE THIS," she wrote on Instagram. 

Brooke's former bandmate, Lauren Jauregui, also couldn't believe her eyes.

"So my mom just texted my brother, sister and I that according to NASA today is the only day your broom can stand on its own because of the gravitational pull and I-" she wrote alongside a photo of her broom. 

Paula Abdul danced her way around her broom and it held up perfectly well. That is, until she knocked it over with her hip. 

"Pajama broom challenge. What are you doing on a Monday Night?!" she captioned the video. 

Rapper Jermaine Dupri, aka JD, thought the entire thing was a hoax, until he tested the theory.

"I really wasn't believing this broom s---, but it's real," he said in a video. 

Actor Jared Leto had no words. He just posted a mind-blown emoji when sharing a video of two brooms standing side-by-side.

Talk show host Wendy Williams became a believer when she saw first-hand how her broom defied gravity.

"Apparently, the Earth is so proper right now that you can balance a broom on the floor. I'm like, 'Really?' I don't care, I don't believe in this. I'm still trying to work out what corona [virus] is," she joked, before seeing it for herself. 

Meanwhile, the folks over at NASA have since spoken out, telling believers there's no such theory. The US space organisation said they never made claims about broomsticks standing unassisted only on February 10, because the household item could do so on any given day of the year. 

"Astronaut Alvin Drew and scientist Sarah Noble respond to the #BroomstickChallenge, showing that basic physics works every day of the year — not just February 10th," NASA tweeted on Wednesday. 

To prove their point, Drew and Noble carried out the challenge in an accompanying video, filmed on February 12. 

"Did you do the Broomstick Challenge yesterday?" Noble asked Drew in the clip. "Well, turns out you can do it again today."

"It's just physics," Drew added.

So what exactly is happening with our brooms? According to CNN, it has nothing to do with the Earth's gravitational pull on a particular day and everything to do with balance.

Apparently, the centre of gravity is low on any broom, sitting just over the bristles. So if you can position the bristles like a tripod, your broom will stand upright on its own — and on any day of the year. Myth busted!
