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.
