Pepsi Max sure knows how to stir up reactions, this time with its newest campaign featuring a magician named Dynamo, who is seen levitating next to a bus as it drives across London.

Despite the spectacle, viewers quickly figured out the trick behind the stunt.

As noted by Yahoo! News, Dynamo's arm is in fact a steel prosthetic fastened to the side of the bus, and his real arms is presumably tucked away inside his jacket.

"His fingers don't move in the clip and there are no people around when he hovers up and down the bus," notes an investigator on Australia's news.com.au Facebook page.

"In fact, at second glance the arm attached to the bus looks pretty phony."

Despite the quick demystification, the buzz surrounding the campaign may be enough for Pepsi Max to call it a success.

More recently, Pepsi Max collaborated with brand ambassador Beyonce with an ad famously titled "Mirrors."

The ad can be seen on Pepsi's official Youtube page with over a million views, and through the brand's use of social media like Twitter, raised awareness for the company.

"We always want to be where our audience is," states Pepsi Max digital marketing manager Aman Matharu.

But which one do you prefer? Beyonce's "Mirrors," or Dynamo's "Levitating Magician?"
