This video comes to us from a theme park in the US, where father Dru Larson was filming his family about to take off on a catapult ride.
"The ropes are looking a little frayed," someone jokes off camera, eliciting nervous laughter.
But just before the ride, at Mount Olympus Theme Park in Wisconsin, is about to be activated, a support rope flies off and hits the floor, appearing to take a big chunk out of it in the process.
The rope comes within about a metre of Larson's 13-year-old son Trevor, who told WISN 12 News: "There was like four inch deep hole.
"It was extremely loud. I didn't really know what was happening. It was a split second. That's how fast it came down."
The Catapult ride has now been permanently taken out of service by the theme park.
