Amazing !!
Of course, this is an illusion. What we saw is not what actually happened.
But this is really good and entertaining.
Especially it was done in front of video camera.
I saw a very similar magic by a Japanese magiciian.

I guess I can download the video file and then watch in slow motion (or frame by frame)
in a video editor program.
Then, maybe or not, I can figure this magic out.
In other magics, I was able to find the secret of the trick out by slow motion replay.

눈뜨고 있는데, 코 베어가는 기술입니다.
그 순간을 알면 재미있을 것 같습니다.

I could not take my eyes off to see how he could that.
Just amazing. Maybe that's why they call it magic.
