One TikTok account by the handle of @coachly.de showed how this is the case with an optical illusion post.
“This is one of the best optical illusions that I have seen, it shows that you cannot trust your brain,” a male voice narrated in the reel.
In the video, users can see two circles side-by-side featuring flashing, colorful edges.
Inside the circles, there are small grey arrows that change directions.
When staring at the circles, it appears as though they are moving up and down, or away from one another.
However, this is not the case, as the TikToker points out.
“The circles are not moving and are also not growing or shirking.”
“You can test this by covering the edge of the circle with your finger and you will see that it’s not changing position.”

How it works
This optical illusion work by tricking our brain into seeing motion via the use of contrasting colors.
Because our brain interprets a change in light as a change in motion, it looks like the circles are changing positions.
In reality, however, they are remaining completely still.
Viewers’ reactions
Since going live a little over a month ago, the optical illusion video has garnered more than 100,000 likes.
Many of the account’s 229,000 followers were left mind-blown, with several thousand taking to the comments section to express their thoughts.
“I can see them moving and not moving at the same time….” one TikTok user wrote, adding a series of ‘shocked’ emojis.
“I thought it was moving at first, pause the video it’s not cap,” a second baffled user chimed in.
“Omg I see it, he means to cover a bit of it at the edge of it and it acc doesn’t move but like how,” a third TikToker remarked.
“So the colors could be why it appears to move. It somehow is tricking your brain,” a fourth person tried to explain.
