Prepare to get Thatcherized.

Adele has a face that is chiseled into the public's mind. She's been a global icon for two decades with a number of mega hit albums and songs. But this photo might be the most unforgettable of all. Perhaps you’ve seen the image in question previously (it seems to make the rounds every couple of years). But in case you missed it—it’s Adele’s face. Normal, just upside down.

Only it’s not normal. In fact, when you turn Adele’s face right side up, what you notice is that her eyes and mouth were actually right-side up THE ENTIRE TIME, even though the entire head was upside down. So when you turn the head right side up, the eyes and mouth are now UPSIDE-DOWN—and you can’t unsee it. Do you feel like you're Alice in Wonderland yet?

Just wait. Things get even more fascinating. Especially because this optical illusion is over 40 years in the making.

Below you’ll find the Adele photo in question. Go ahead. Take a look at it. Then turn the image upside down.

Crazy right? And just a little terrifying?

As the Facebook post explains, this mind-boggling image highlights a phenomenon known as the Thatcher effect. Our brains, so much more used to recognizing faces that are right-side up, have difficulty detecting specific changes once a face is upside down.

Seeing that everything is more or less where it should be, our brains don’t notice anything out of the ordinary in Adele’s face until we turn her face back to a normal position.

The Thatcher effect got its name from British Prime Minister Margaret Thatcher, on whose photograph it was first demonstrated back in 1980 by Peter Thompson, Professor of Psychology at York University.

This demonstration was one of the first to explore just how facial recognition works, and certainly the first to suggest that humans (and monkeys, it turns out) process faces on a more holistic level, rather than by individual components like lips and eyes. There's even evidence that rhesus monkeys and chimpanzees experience the Thatcher effect, meaning it may have deep roots in the evolutionary biology of mammals.

Since its publication, there has been a wealth of research exploring how our brain takes in both subtle and striking facial configurations.

Funny enough, it was once believed that this illusion only worked on the Prime Minister’s face. But as Adele has proven, anyone can be Thatcherized.

Watch "The Starry Night" come to life with this optical illusion.

Vincent Van Gogh's "The Starry Night" is one of the most recognizable and beloved paintings in the world. It was completed in 1889 and has been part of the permanent collection of the Museum of Modern Art in New York City since 1941. It is not up for sale, but if it were to go to auction there is a chance it could fetch as much as billion dollars.

Such a priceless work of art is perhaps a strange object for a parlor trick, but trust me when I tell you this one is worth it. Whether they are oases in the desert created by heat shimmer, an elephant with an indeterminate number of legs or straight lines that look crooked, optical illusions can throw our brains for a loop. They can also be super fun, and an optical illusion that makes the "Starry Night" painting turn into a moving picture is most definitely fun.

The illusion, shared by Alex Verbeek on Twitter, involves two steps. First, you stare at the center of a spinning spiral image for 20 seconds, then you look at the painting. Staring at the spinning spiral isn't as easy as it sounds—it makes your eyes buggy and your brain hurt a little—but even if you don't do the full 20 seconds, you can probably get the effect.

Aim for staring at the center of the spiral for at least 10 seconds, then watch "The Starry Night" come to life before your eyes. (You have to click "play" first, by the way. The spirals need to be swirling.)

Want a larger version of the painting to try it out on? Here you go:

The effect doesn't last long, but phew. Our brains are so bizarre.

According to a 2009 study by Japanese researchers, motion in optical illusions is still processed in the brain the same way real motion is. So don't be surprised if the moving painting makes you feel a bit woozy, if you're prone to motion sickness.

It's hard to believe that Van Gogh's "Starry Night" could be improved upon, but here we are. Definitely a "moving" experience to share with your friends.

Tom Hanks and Bill Murray


What do you think?

SCROLL DOWN FOR THE ANSWER

Given the narrow beauty standards in Hollywood, there are a lot of actors and actresses that look look amazingly similar.

Heath Ledger and Joseph Gordon-Levitt look a lot alike…



As do Katy Perry and Zooey Deschanel…

But has anyone ever said, "You know which 60-something actors look identical? Tom Hanks and Bill Murray." Because they don't look alike. Although, funnily enough, Bill Murray did famously turn down the leads in Hanks' hits "Forrest Gump" and "Philadelphia," but I'm guessing nobody has ever screamed, "Loved you in 'Ghostbusters'" at Hanks as he walked down the street.

But for some reason, call it fate, call it luck, call it karma, the man making the "waaah" face in the orange raincoat above could easily be either man.

Here's what people are saying on Facebook:

The truth (should you choose to accept it):

The photo above is of Bill Murray and Laura DiMichele-Ross holding her crying son, Alexander, at the Alfred Dunhill Links golf competition at St. Andrews in October 2012. DiMichele-Ross posted the photo to a popular Facebook blog "Reasons My Son Is Crying" in May 2013. The photo resurfaced in October 2016 on the Today Show website, reigniting the controversy all over again.

Regardless of what the Internet is saying, DiMichele-Ross backs her original claim that it's Murray. "It's totally Bill," she reiterated in a comment on her post. "I can vouch cause I'm the one in the photo with the massive grin thinking 'Oh my god this is going to be an awesome photo!'"

The Ames window trick.

Optical illusions are universally beloved for how they trick our brains and blow our minds. There's a reason we enjoy magic shows and Escher paintings and are mesmerized by fake oases in the desert. We love seeing things that bend our perceptions of reality, and the science behind the magic always proves fascinating as well.


The Ames window is a pretty well-known optical illusion, but it's always cool to see. When spun, the angled window appears to oscillate back and forth instead of spin all the way around. But this video adds a twist that makes the effect even more mindbending—our brains simply can't process objective reality mixed with an optical illusion.


The YouTube channel Curiosity Show explains the science of the illusion and gives a DIY demonstration for making your own Ames window. But wait until the pen gets taped to the window and spun. This is some real-life magic right here. Mind. Blown.
