Pinhole Cameras


You will need these things:
 * A Long Box (The longer the box the bigger the picture will be)
 * A Pin or Needle
 * Some Glue
 * Some Tin Foil
 * A Ruler
 * A Pair of Scissors

How to Make the Pinhole Camera
Step 1: Cut a square hole in the top of the box on the smaller end that is about 1 by (use your ruler!) Step 2: Draw a line around the hole with some glue, then put a square on tinfoil on top so that the hole is covered. Step 3: Once the glue is dried, poke a tiny hole in the tin foil with the pin. Step 4: Cut a hole on the long side of the box so that you can see the bottom of the inside of the box.

How to Use the Pinhole Camera
Next time you know there is going to be a solar eclipse, point your pinhole camera towards the sun. The light will shine in through the pinhole and out onto the bottom of the box. Looking right at the sun can hurt your eyes, so using a Pinhole Camera is a fun and safe way to watch eclipses.
