I think it looks fake, yet it’s still interesting to observe:

A strange blue cloud seen floating and darting around customers, freezing for 30 minutes and then speeding from an Ohio gas station, remains unexplained even though it was caught on security cams.

The ghostly image was seen moving near and over cars at a Marathon gas station located near the corner of State Road and Pleasant Valley in Parma on Sunday.

There is a video and images on the news site of the blue cloud moving about: LINK
