The guy showed miracles of flexibility
The talents of some people are sometimes amazing. And this applies not only to artistic and musical abilities, but also to physical ones in some way. For example, can a person crawl through a tennis racket? Most probably, but definitely not the hero of this video.
This guy is so dexterous and flexible that doing such a trick is a completely doable task for him. It’s hard to imagine how much he had to train for this, but the result is really very impressive.
