How do they trick our eyes?

They trick our eyes by making things look different than they really are, like when you stare at a picture and it changes shape or color.

Imagine looking at a piece of paper that has lines on it, but instead of straight lines, they seem to wiggle. That’s because your brain is trying to make sense of the lines, just like when you try to read upside down, your brain gets confused and mixes things up!

Your eyes send messages to your brain, which then draws a picture of what you're seeing. Sometimes, those messages can be a little mixed up, or the pictures are made in tricky ways, like with shadows or colors that change when you move your head. That’s why some drawings look like 3D shapes, even though they’re just flat on paper!

It's kind of like when you wear glasses and suddenly everything looks clearer, your brain is just getting a better message from your eyes! They trick our eyes by making things look different than they really are, like when you stare at a picture and it changes shape or color.
