Things Are Not Always As They Seem

I'm always amazed at how easy is it to trick the brain. For example, check out this cool optical illusion. Any guesses on how it's done?

May Light increase!

There must be some kind of water vessel (a saran wrap bubble?) in the progressively larger glasses that fills the rest of the only tip off to this suggestion would be that the 'milk' gets fairly pale towards the end.
Do you know how it works?

Evi: You are on the right track in your thinking. If you find this video on youtube, you'll actually see it linked to a video that explains how it is done. Definitely a cool trick though!
