Imagine sipping on your coffee and tucking into a proper good slice of cake only to see something right out of a horror movie right before you very eyes.
Well, for a bunch of unsuspecting customers, this was exactly the case after the perfectly-executed prank was impressively pulled off leading to a whole bunch of hilarious reactions.
People are hailing the mind-boggling witchcraft prank, which has since gone viral, 'one of the best ever seen'.
The whole prank first came about as a clever and very outside-the-box way of promoting the new Carrie flick remake with a little bit of spice.

Studio marketers for the film commissioned the elaborate stunt which took place at a New York City coffee shop of all places.
Almost the entire place was previously set up by the pranksters, including a 'fake wall' being erected slap-bang in the middle of the joint with a pulley system was then attached to it. Tables and chairs were designed to be 'remote controlled' while pictures and books were 'spring loaded'.
Actors were then seated inside as a whole bunch of hidden cameras were dotted about the shop to be sure to capture every single reaction.
Oh yeah - and they also enlisted the help of a very convincing stuntman.

The video uploaded to YouTube begins with the overlay text: "Time to f*** with some customers."
And that they did.
The prank effectively sees the stuntman acting as barista who accidentally spills coffee all over a woman's laptop.

Naturally, the irate woman then uses her 'telekinetic' powers in a frenzied fit of rage to throw him up against the wall without even touching him.
It's fair to say that people absolutely lost their sh*t.
The video's description reads: "What if telekinesis was real? How would you react? Our hidden camera experiment captures the reactions of unsuspecting customers at a New York City coffee shop as they witness a telekinetic event."
It has since on to clock up more than a staggering 79 million views and nearly 40,000 comments since it was first uploaded back in 2013 - it's clear people couldn't wait to share their reactions.
One YouTube user declared: "This is probably the most authentic camera prank ever done in history of pranks."

"Honestly, coming back to this eight years after the last time I watched it, it still remains the single greatest prank ever pulled," penned another.
A third commented: "I revisit this video at least once a year and just applaud everyone who worked on this.
"They executed everything perfectly and the genuine reactions of the people in attendance just puts the cherry on top."
It sure does.

On one clip, which was reposted to Twitter, one person hailed the stunt as: "One of the best pranks I’ve ever seen… I know these people were about to have a heart attack."
A second dubbed it the 'world's best crafted camera prank'.
"That was the best prank I've ever seen," echoed a final social media user.
I wonder if it will ever be topped? Guess we'll have to wait and see...
