This is scary video of an ice hockey rink collapsing in Slovakia.
It was apparently a brand-new ice hockey rink, where young hockey players were training with former NHL player Richard Zednik.
If you notice, nothing seems out of the ordinary at the beginning of the video, but then you hear some strange noises, and then the video jumps to the roof collapsing while everyone inside the rink is trying to flee to safety.
Details are sketchy, but the good news is that nobody was hurt.
That's amazing, considering most people just looked like they were just standing around as the building collapsed around them.
