Editing Binocular Vision (section)

== What To Say ==

Alright, now I am going to show you how to see a hole in your hand. First, everyone needs to take a tube and put it up to one eye. Hold the tube right next to your face and put your hand near your face. Now put your other hand next to the tube, closer to the end and look through both eyes – you can see a hole in your hand!! So, why do you think this happens?? Well, when you see something, the brain takes images from both eyes and combines them together to form the image that you see. In this demo, your brain is getting a different image from each eye and when it puts them together, it looks like you have a hole in your hand!!
