I have been working on a optical illusions science project for our science fair. I have done a poster with a bunch of optical illusions, and I even got a certificate for participating in the science fair!
I will tell you the 3 main types of optical illusions with examples: The first type of optical illusion is called a reverse illusion. The first two optical illusions below are this type of illusion. You can see them as one thing, or something else.
Another type of illusion is called a moving illusion. They will seem like the picture is moving, but it isn’t. This is the three optical illusions below.
These pictures are not moving!
Another type of optical illusion is a mind illusion and you will think that something that is there is not there, or something is not there but you think it is there. This last picture is this type of illusion.
