How to make a Box Pinhole Projector

Making a pinhole projector is a fun way to safely observe a solar eclipse. Here's a simple way to create a box pinhole projector:

Materials you'll need:
1. A box (e.g., shoebox or cereal box)
2. Aluminum foil
3. Tape
4. Scissors
5. A pin or needle
6. White paper or a sheet of poster board

Steps:
1. Cut a small square or rectangle hole in one of the short sides of the box.
2. Cover the hole with aluminum foil and secure it with tape, ensuring it's flat and smooth.
3. Use a pin or needle to poke a small hole in the center of the aluminum foil.
4. Attach a piece of white paper or poster board on the inside of the box, opposite the foil-covered hole. This is where the projected image will appear.
5. With your back to the Sun, position the box so that sunlight shines through the pinhole onto the inside surface.
6. Look inside the box, and you should see an inverted image of the Sun projected onto the paper.

Remember, never look directly at the Sun without proper eye protection, as this can cause serious damage to your eyes. The pinhole projector provides a safe way to indirectly observe solar events.
