How to (Safely) Marvel at a Solar Eclipse

Many of us share a common childhood memory—standing outside with our schoolmates gazing up through specially crafted glasses to catch a glimpse of our first solar eclipse. Also known as the “ring of fire,” an eclipse happens when the moon comes between Earth and the sun during its orbit. It’s a majestic sight and one that shouldn’t be missed, but looking directly at a solar eclipse is incredibly dangerous. Your eyes dilate due to the low light levels. At the same time, ultraviolet light is still exuded around the eclipsed sun in what is called a corona, or halo, allowing UV light to escape, which could cause serious, permanent damage to your retinas. Never view an eclipse without using the proper equipment and technique. Thankfully, it’s easy to make a pinhole projector to help shield your eyes from those dangerous UV rays, while still allowing you to capture one of nature’s most incredible displays.

What You’ll Need

Shoebox

White paper

Scissors

Tape

Aluminum foil

Pencil

Directions

1. If the inside bottom of the box isn’t white, cut out a piece of white paper to the correct size and tape it to the bottom of the box.

2. Cut out two rectangles the length of the box top from opposite ends of the box. This will create two openings: one where you’ll place foil and one through which you’ll view the eclipse.

3. Tape aluminum foil over the left opening.

4. Use a pencil to poke a hole in the center of the foil. The size of the hole should be more than 2 inches but not more than 3 inches wide.

5. Stand with your back to the sun.

6. Hold the finished pinhole so that the sun’s rays shine onto the foil with the pinhole.

7. Look through the right-hand side of the box for as long as you like—you are looking not at the sun, but at a refracted image. Move the image until the eclipsed sun appears at the bottom.
