Mission STS-90

What is it?

After doing that trick, you will never look at a picture the same way again. Your visual cues allow you to see more than one view of a picture. You do not believe me, well try this: Looks like something familiar? An image will appear: you only have 15 seconds to look at it and decide what it is.


Image 1


You were right if you said the image looked like a glacier. Now, if this same image is turned upside down, do you see the same thing (doesn't it remind you of some kind of falls)?


Image 2


Your visual cues made you see a glacier on the right side up picture, but you saw Niagara Falls when the picture was turned upside down. Want to try it again again?
