Click here to try seeing 3D images through crossed eyes!
It is possible to see images in 3D by crossing your eyes, it is called "Stereoscopy". There will be two images of the same thing, yet one image is designed for the left eye and the other for the right. When you cross your eyes you see one image that combines both the right eye and left eye image to give you one 3-dimensional image. This is basically the same way we watch 3D movies, except the glasses we put on do the work for us. It's fun to try this method because you don't need glasses at all just the ability to cross your eyes! Try looking at the following images in 3D by crossing your eyes!
