How to build a pinhole solar eclipse viewer

Don’t have solar eclipse glasses? No problem.

Storm Team 7’s Christy Henderson shows you how to make a pinhole viewer with items you probably already have at your home.


  • Cardboard box (the longer the box, the larger the image)
  • Scissors
  • Aluminum foil
  • White paper
  • Clear tape
  • Duct tape


1. Cut two holes on the same side of the box

2. Tape aluminum foil over one of the holes in the box. Make sure no light gets in around the edge of the hole.

3. With clear tape, attach the white paper to the inside of the box on the opposite side of the holes. This will be your movie screen.

4. Close the box and tape it shut with duct tape. Make sure the only light entering the box is from a pin hole you will make in the aluminum foil. Speaking of which…

5. Using a small, uniform poker like a thumb tack, poke a hole in the aluminum foil.


Turn your back to the sun.

Look into the hole you cut in the box.

Move the box around until you can see the light from the sun enter through the pinhole and appear at the back of the inside of the box on the white paper.
