Have you ever seen a book like this before?
If you look at the page the right way, you can see a 3D picture hidden inside the 2D image. It’s not easy at first, but the trick is to relax your eyes and look “through” the picture instead of focusing on it directly. The easiest way to do this is to put the picture close to your nose, then slowly pull the book away. It takes practice to get it right.
I used to love these books when I was a kid. I got one as a gift when I was fairly young, and for a long time, I simply couldn’t see the pictures. I kept trying every day and eventually figured out the technique, and now I can see them easily.
Give it a try here!
