A short clip recorded inside a tunnel is going viral because netizens are baffled by what they can see on the road. Clip is given in the last slide.

This short video shows drivers panicking at what appears to be a huge pit.

An unassuming driver was cruising through the tunnel when he noticed the strangeness of the road.

The man who recorded the video realizes there is only water on the road, which looks like a pit.

This optical illusion could be exactly the opposite of a mirage.

A mirage is an optical illusion caused by atmospheric conditions, especially the appearance of a sheet of water in a desert or on a hot road caused by the refraction of light from the sky by heated air.

It basically makes a road look wet with water from a distance. In the case of the tunnel, the water looks like a pit. See the video in the next slide.
