Apparently, if you can solve this puzzle in just ten seconds, you're certified as a genius.
From The Sun:
Well, personally, I got the answer right, but it took me well over ten seconds. So, sadly, it seems like I'm not a genius.
Optical illusions are pictures or visuals that trick our brains into perceiving something different from what's actually there.
This intriguing phenomenon happens through a process known as "filling-in," in which the brain chooses particular elements from the visual information it gets from the eyes to highlight, IndiaTimes reports.
As a result, the various layers of an image can appear differently depending on where the focus is placed.
Are you ready? Take out your stopwatch and set it to 10 seconds.
If you are able to count all the eggs in the carton on time, you must be a true genius.
But there's no need to panic if you couldn't figure it out, as it turns out only five per cent of people manage to solve it.
If your initial response was 16, then you are off the mark because you must account for the hidden eggs.
Ready to give it another shot?
First, begin by considering how many there would be if this were a 3D image, starting from the base.
In a 4x4 arrangement, there would indeed be 16 eggs on the bottom alone.
Moving up to the next row, where there are three eggs, applying the same logic would yield nine.
Continuing, you have a 2x2 arrangement, which is four eggs plus the lone egg at the top.
When you add them all up, there are a total of 30 eggs.
