Here's a great optical illusion you can do with an empty paper towel
tube. Hold it next to your hand and then let your eyes relax, focus
on the distance and it will appear that you are looking in a hole in
your hand! This is one that kids will really like, so next time you
are looking for a new way to entertain a child, try this technique!
