Is it possible to throw a needle hard enough that it pierces through glass? That’s an incredible skill Shaolin monks, featured in a new video by YouTubers The Slow Mo Guys, say they possess.

In fact, it’s one of the 72 Shaolin secret arts, that monks say takes 10 or more years to master, reports the NDTV.

The Slow Mo Guys invited three Shaolin monks to show off this seemingly impossible feat - and recorded it in slow motion to reveal how the Shaolin trick is really done. The video posted just two days ago has already been viewed over two million times.
In the video, the Slow Mo Guys hold up a balloon behind a pane of glass. A Shaolin monk gathers his energy and throws a needle at the glass, just like a dart. Incredibly, it smashes and the balloon pops. Sounds incredible, doesn’t it?

In the video above, at one point, the footage is slowed down to a few thousand frames per second. It then becomes clear that the Shaolin monk threw the needle with such force that it caused the glass to shatter and send shards flying.

It’s these glass shards that actually caused the balloon on the other side to pop. The needle actually ricocheted off the glass due to the force at which it hit the pane.

Still, the ability to throw the needle hard enough to crack class is pretty impressive. When one of the Slow Mo Guys tries his hand at it, the balloon remains intact though he does manage to put a slight dent in the glass pane.
