Unlike the videos we post where some idiot isn’t paying attention and then falls down or runs into something, this one is slightly different. Yes, we have a girl falling through a hole, but she falls through a hole that wasn’t even there until she walks over it.
The hole appears in the sidewalk only as the girl walks over it and like magic, she’s gone.
Apparently, running water under the pavement caused the problem. The girl was predictably terrified and had to be rescued, but it appears everything worked out in the end.
