Directions: First look at the waterfall. Then proceed to find where the water is coming from. As you look down the canal of water, try to figure out where the height of the towers are. The ground-to-sky perception is off in this picture, making this apparatus impossible. Reason: This, again, is impossible in a 3-d world, but in a 2-d world this is absolutely possible. This picture distorts the image by the person's perspective. The person looking at this will obtain the imagery in their eye as normal, as the brain begins to perceive it and study it a little bit more, the person will realize that this is not possible. This illusion has the brain confused because our brains always assume that adjacent edges must join, and that's how they get you.
