Opal diffuser films are milky white (opal white) and contain a scattering additive specially developed for this application to ensure uniform light diffusion.

You see an object because light rays reflected from the object shine into your eye, creating an image on the retina inside your eye. Signals sent to your brain allow it to recreate the picture of the object.

Spherical Aberration Spherical aberration is an axial aberration, affecting the entire field equally, including stars at the center.

The surface of a smaller drop is even more curved, bending the light rays even more inward. The result is a larger magnification: the object appears even larger. Changing the position of the water drop with respect to the letters and your eye will also affect how much larger the object appears.

A water drop has a dome-shaped surface, and thus, serves as a convex lens. Due to something called the capillary effect, a layer of water in a cup shows a surface that is bent slightly inward. It will act as a concave lens that bends the light rays outward. As a result, letters seen through the layer of water in a cup appear smaller than they are. When you combine several lenses, the magnification factor of the set of lenses is the product of the magnification factors of the individual lenses.

Any clear liquid will work as a lens. As long as the bottom and top surfaces of the layer or drop are not parallel, the lens will change the appearance of the object. Depending on the liquid, the magnification factor of similar drops made up of different liquids will vary.

To see an object, light rays reflected from the object need to fall into your eye. Light rays usually travel in a straight line to your eye, but things can change when a transparent material, such as glass or water, gets in the way. Did you see how objects appear larger when viewed through a water drop? The surface of a water drop curves outward to make a dome, and this outward, or convex, curvature bends light rays inward. As a result, the object appears bigger than it is.

Are you ready to bend light, magnify letters, and have fun with drops of water—all while getting a glimpse into how lenses work? Lenses are the key components in eyeglasses, contact lenses, binoculars, telescopes, and magnifying glasses, just to name a few devices. With this activity, a homemade magnifying glass is only a drop away!

Although a light ray bouncing off an object usually travels in a straight line to your eye, things change when a transparent material like glass or water gets in the way. When a light ray traveling through air enters such a material, it changes direction, creating a sort of kink. Another kink is introduced when the ray leaves the material. Therefore, the final image of the object in your eye might be different because the light changed direction on its way to your eye. Your brain is unaware of these kinks, and expects an image created by rays that traveled in a straight line. As a result, it might reconstruct a picture that is different from the initial object. Your eyes and brain might have been fooled!

Lenses use these kinks to make objects look bigger or smaller, closer or farther away. A convex or dome-shaped lens bends light rays inward, which results in the object being perceived as larger or closer. A concave lens—a lens that curves inward—bends rays outward, giving the perception that objects are smaller or farther away. There is no overall bending of light for a flat lens; you perceive the object as it is.
