He suggests making a pinhole projector.
- First take a piece of paper and poke a hole in it with a pen or pencil.
- The hole should be tiny, about 1/8 inch diameter (you can experiment with different sizes).
- Hold the paper so that sunlight goes through the hole, and let the light fall onto a second piece of paper.
- You will see a tiny image of the sun. When the eclipse happens, you will see a little crescent - the eclipsed sun.
