A mind-bending optical illusion has been doing the rounds on TikTok this week, once again proving that our perception of reality is much more fragile than we'd sometimes like to admit.
Originally posted by user @beatonthebeeb, the video shows a picture of three cars driving uphill and posits a simple question to the viewer- which of the vehicles is the biggest?
At a glance it seems obvious - the one at the top of the hill clearly looks larger than the other two - but upon closer inspection, it would appear that things aren't quite as cut and dry as they initially seem.
As it explains in the video, it actually turns out that the three cars are all the exact same size, but because we naturally assume that the one at the top of the hill is further away than the others our brains automatically enlarge it in order to make the picture 'make sense'.
And if you're still sceptical after all that, the video even goes one step further, removing the background and placing the vehicles side-by-side to prove that not only are they the same, they're actually the exact same car! Wow!
This isn't the first time an optical illusion has baffled the internet either- in fact, it seems like every few months a new brain teaser pops up on our feeds to melt minds and cause arguments in the comments.
Case in point- check out this viral video which also did the rounds on TikTok earlier this year, in which a man's head appears to be completely separated from his body while he swims in a pool.
The video, which has had more than 7.5 million views, was shared on TikTok by Micah Wallace (@themicahwallace), leaving others baffled about how it happened.
Although the solution was actually quite simple, with the illusion being created by a scientific incident known as refraction, that didn't stop people from claiming that the clip had 'fried their brains' as they struggled to comprehend what was right in front of them.
And who could forget this viral photo of a leopard hiding in a ditch? That one proved to be a particularly tricky nut to crack, and to this day I'm still not really certain where the animal is.
(If you really want to find out where the cat is hiding, you can view its location here).
Not all of these illusions are new - some of them have been doing the rounds for years in fact, but it just goes to show that no matter how old you are, everyone appreciates a good head-scratcher!
