A video of four spoons has gone viral on TikTok. The black-and-white clip challenges users to spot the red spoon, but it’s not as simple as you might think. This seemingly easy game has been stumping plenty of users on TikTok, and even we didn’t get it right at first.
Check out the video below to see if you can find the red spoon (and if you can’t get enough of this type of brain puzzle, then don’t miss our optical illusions roundup).
If you haven't already guessed, the red spoon is number four in our line-up. And if you’re thinking, ‘but number four seems too dark to be red’, then we might have an explanation for you. According to Sage Edge, what we are seeing here is the Purkinje shift, which means that colours with larger wavelengths, like the colour red, will appear darker in black-and-white photos (see below).
The TikTok posted by user BeckyBaw777 has racked up a hefty 7.4 million views and its popularity doesn't seem to be slowing down with tens of thousands of users flooding the comment section with their answers. Some users were able to pick up on the red spoon straight away, with some commenting things such as, "I said 4 I got it right I'm screaming," and, "I said 4 with a little hesitation". But most were completely stumped by the photo, and one user commented, "My mind: It's 4. Me: Nah it's 1," and another simply confessed, "I guessed 3".
