It doesn’t seem to make a lot of sense. I first heard of that actually being possible in my Chemistry class. I wondered if looking but not seeing is even possible. Surprisingly enough, it is.
I could give a lot of examples, but the best example would be the video with the gorilla. A lot of changes take place, and you won’t notice most of them. Most people won’t notice the gorilla walking in the middle of the screen. Most people won’t see the curtain colors change. Other things change, but I don’t want to give everything away.
It is actually possible to look at something without actually seeing it. You can see the fascinating video on YouTube by clicking here.
