Spooky Science #3 - Hole in the Hand
We are having so much fun with our Spooky Science. :) It is now time to see through your hand!
How to see a hole through your hand:
Equipment: 1 sheet of paper, your hand, your eyes
How to do it.
Roll the paper into a tube. We thought a tightly rolled paper with an opening between a quarter or fifty cent piece worked the best. Hold the tube with your right hand and look through it with your right eye. hold your left hand open on the left next to the paper. There should be a hole!
How it works:
Your right eye sees the hole in the paper tube and your hand, your left eye sees your hand, both eyes composite the images in the brain and combine them into one image. Nifty, huh?
