"Arrow Trick - Amazing"



This trick is best performed by people who don't know whether they're coming or going.

That is either very cool or very disturbing. I'm not sure. My brain doesn't like it. Is it akin to looking in a mirror?

"Very easy illusion to do at home trying it yourself.

"When the arrow is moved to a particular distance behind the glass, it looks like it reversed itself. When light passes from one material to another, it can bend or refract. In the experiment that you just completed, light traveled from the air, through the glass, through the water, through the back of the glass, and then back through the air, before hitting the arrow. Anytime that light passes from one medium, or material, into another, it refracts.

"Just because light bends when it travels through different materials, doesn't explain why the arrow reverses itself. To explain this, you must think about the glass of water as if it is a magnifying glass. When light goes through a magnifying glass the light bends toward the center. Where the light all comes together is called the focal point, but beyond the focal point the image appears to reverse because the light rays that were bent pass each other and the light that was on the right side is now on the left and the left on the right, which makes the arrow appear to be reversed."

It looks as if distance from the focal point is critical in achieving the desired effect. Cool video.
