Solar eclipse 2024: How to make a pinhole viewer

Here are instructions to create a pinhole viewer that will project an image of the April 8, 2024, eclipse.

Materials

• Cardboard box

• Scissors

• Aluminum foil

• Pencil

• Thumbtack

• Tape

• White sheet of paper

Instructions

• Trace a short end of the box on the white paper. Cut it out and insert the paper into the box, at the end you traced.

• Cut two square holes on the opposite end of the box on the left and right, leaving a small area remaining in the middle. If using a cereal box, tape the middle to help it stay together.

• Cover one of the square holes completely with aluminum foil.

• Take the thumb tack and punch a small hole in the center of the foil. By facing away from the sun, light will enter the viewer through the tack hole and project a clear image of the eclipse on the white paper.
