Everyone sees a red box – but you have a high IQ if you can figure out what’s really going on in under 15 seconds

IF you can figure out what's happening in this optical illusion in less than 15 seconds, you might have a high IQ.

At first, it appears as if the person is holding a solid, 3D red box but it's soon revealed that the shape is actually flat.

The illusion was created by Olivier and Chloe Redon and is known as the "Oh La La Box," which won the in 2021.

At first, it's easy to see a bright red box but as the clip continues, you'll see that there's no box at all.

Can you figure out how it works before we reveal the answer?

You'll soon find out that the illusion is very deceiving and uses reverse perspective to play a trick on the eyes.

The box is actually just two peoples of cardboard that are carefully placed on top of one another and folded.

But when looked at from a distance, the cardboard looks like a 3D box because of the way our brains process images and spatial awareness.

It's called "reverse perspective" and it's a trick used in many optical illusions.

The Neural Correlate Society, which awarded the illusion, researches how these brain teasers play tricks on us.

In the video's description, the science behind the illusion is explained: "The two pieces of the box (front and back) visually fuse together to create what appears to be a normal ordinary box.

"When both pieces (with inverted (also known as reverse) perspective) of the “Oh La La Box” are properly arranged and viewed from a precise location the box is completed."
