What does it look like to have a huge chunk of rock go flying past your head and almost kill you? Well, a bit like this...
A crowd of people who went to see a building demolition in the Czech Republic got a little bit closer to the action than they would have liked after this video of a bystander nearly getting killed has surfaced online.
The video has a slow-motion replay of the rock that goes flying through the crowd at head-height, narrowly avoiding a few people by a matter of inches. One guy even dodges quickly, having spotted it approaching, which may well have prevented it from hitting him.
As you can see, it's a big chunk of rock, and at the very least would have done some serious damage to anyone who was on the receiving end.
