Optical Illusion?- Sleepless in Seattle (view previous photo)
Experiment-->A wine glass half filled with water with a beautiful reflection of Seattle's Skyline.
The result-->as you can see,the air portion within the glass,the background appears normal, however; in the water portion, the opposite background is rotated horizontally.The shape of the glass with the water resulted in some type of concave mirror that vertically inverted the light causing the effect. I am not entirely sure about this but I do know that the unique shape of the wine glass is a factor as this effect is not possible with a regular glass filled with water.
PS; PHOTO ROTATED- to see how it would look like, from different perspectives
