Zion Oil & Gas Inc (ZNOG)

Note the colors: The red tower’s reflection changes from darker to lighter suddenly as you look down the reflection towards the bottom of the picture. There’s a definite line where the reflection is darker above and lighter below, indicating a change in what is on the surface, a darker substance floating on top.
Don’t read too much into the picture. One pint of oil can cover one acre of water in a body of water that is not still, less oil is needed under ideal conditions like we have here.
