Optical Illusion Bookmarks

Cut out these 3 optical illusions and use them as bookmarks. You could laminate the bookmarks to protect them. If you do not have a laminator, you can sandwich the bookmarks between two pieces of clear strapping tape. Trim the edges of the tape and you will have a strong bookmark.

The top and bottom bookmarks demonstrate the blind spot. Do you see a triangle in the middle bookmark? Is it really there? For more information about these illusions, go to the vision page.
