Wikipedia
Googly eyes, or jiggly eyes are small plastic craft supplies used to imitate eyeballs. Googly eyes traditionally are composed of a white plastic or card backing covered by a clear, hard-plastic shell, encapsulating a black plastic disk. The combination of a black circle over a white disk mimics the appearance of the sclera and pupil of the eye to humorous effect. The inner black disk is allowed to move freely within the larger clear plastic shell, which makes the eyes appear to move when the googly eyes are tilted or shaken.
The plastic shells come in a variety of sizes ranging from to over diameter. The inner disks come in a variety of colors including pink, blue, yellow, red and green. Googly eyes are used for a variety of arts and crafts projects including pipe cleaner farm animals, silly sock puppets, mischievous pranks, and other creations. Googly eyes may also be attached to inanimate objects in order to give the objects a "silly" or "cute" appearance. This use often personifies the objects for a humorous effect.
