The video showed 31-year-old Boris Oravik swimming under the ice in the Vysuki Tatry area in the High Tatras.
As Oravik tries to get out of the cold waters, he finds himself trapped under the ice and unable to find an opening to the surface, despite being directed by his colleagues.
Oravik’s colleagues tried to break the ice to get him out, while the adventurer seemed unable to follow his companions’ directions towards the exit area.
After a number of attempts, Oravik was able to get out of the cold water, and appeared to be in good health.
Oravik published a video of his dangerous experience, accompanied by a warning not to try to do such a thing because he needs training and experience, according to the British newspaper, “Daily Star”.
