A few weeks back, you might have seen a video floating around of what appeared to be a Viner Kevin Parry playing catch with his own reflection. It’s hard to look away from, but it’s obviously impossible. That led commenters to speculate on how the trick was done.
I want my cake to be fluffy and delicious and always enough for seconds. Maybe it can be a little decorative and fun and hide a joke somewhere but what I’m not prepared for is a cake to wreck my brain before it pads my stomach.

It’s all about the perspective. Well, it’s also a little about how easily our eyes can be tricked. Here’s optical illusion expert BrussPup pulling the old perspective trick on us by making us think something is real when it’s not and making us believe something is fake when it’s actually the real object. It’s a fun…
Some of our favorite murals are the ones that deceive your eyes. You're walking along when suddenly you spot a hole to another universe in the sidewalk or see a 3D object hovering in the air — only to realize that it's just paint against a flat surface. Watch these videos to see how those illusions come to
István Orosz makes prints that are beautiful on their own, but when you place a cylindrical mirror on the surface, a hidden image is revealed. Secretly, the illustrations contain anamorphic portraits of famous men.

When you've been driving down a long, straight road, and you suddenly come to a stop, does the road seem to rush away from you?

In an experiment that could explain why some people see ghosts, participants were made to feel as though they saw phantoms around them and that ghosts were touching their backs with invisible fingers. The illusion was so real that some test subjects begged for it to stop.

How can I put this delicately? Do you have a vibrating toothbrush? A personal body massager? If you do, you can perform some amazing sensory illusions, like making your nose seem huge or your waist small. Finally, an excuse to give the TSA agents when they search your bags!
We're suckers for the mind-blowing properties of a perfectly placed anamorphic image. And in this video, there are flat images hiding in a collection of Gundam toys. Can you tell which ones are real?

Want to put someone through "humanity test," like the Bene Gesserit did in the Dune series? First you'll need a needle filled with "meta cyanide." That, I can't help you with. Then you need a box that can cause burning pain without harm. It's all possible if you use the "Thermal Grill Illusion."
The latest installment of AsapSCIENCE opens with a demonstration of the McGurk Effect, a powerful auditory illusion that demonstrates how what we see influences what we hear. But even more baffling is the Shepard tone illusion – a sort of sonic barber's pole that seems to continually ascend in pitch, without actually…
Like all the best optical illusions, you'll fall for this one even when you know how it works.
