How to Make an Easy Model of an Eye
The eye is a wonderfully complex organ. (eye image by Artyom Davidov from

The human eye is on of the most complex organs in the body, second only to the brain. In fact, with its many neurological connections, the eye has become one with the brain more than any other organ. Light enters the pupil of the eye, passing through the lens. The inside of the eye is filled with fluid. the back of the eye is covered with the retina, which is made up of a series of structures called rods and cones. These structures convert the light into neurological impulses that the brain can interpret. To better understand the eye, try creating a model of it.

  1. 1

    Cut a single egg cup from an empty egg carton. Poke a small hole in the bottom of the egg cup. This will represent the eye socket.

  2. 2

    Mix the gelatin with hot water. Allow the fluid to cool. Pour the thick fluid into the squirt bottle.

  3. 3

    Squirt the gelatinous fluid into the balloon. This represents the vitreous fluid inside the eye. Fill the balloon until it is about 1 and 1/2-inch in diameter. Tie a knot in the end of the balloon.

  4. 4

    Poke the balloon knot through the hole in the bottom of the egg cup. Place the egg cup on its side. The balloon tail poking out of the back of the egg cup represents the nerve bundles that emerge from the back of the eye socket.

  5. 5

    Colour the paper reinforcement an eye colour of your choice. This will become the iris of your model. Using a black marker or pen, draw a circle in the middle of the iris, this is the pupil.

  6. 6

    Cut a piece of clear tape smaller than the paper reinforcement. The clear tape represents the lens of the eye. Stick the reinforcement to the tape.

  7. 7

    Stick the tape---with the reinforcement attached---to the front of the balloon.

Tips and warnings

  • Label the parts of your model to make the project clearer to your audience.
  • Use caution when cutting and poking the hole in the egg carton.
