Step 2: Draw

Starting 2 inches away from one end of the tube, draw a rectangle that is 2 inches long and 1 inch wide.

Step 3: Cut

Cut out the rectangle. If using scissors, it maybe easier to start by punching holes into the four corners and cutting from there. That is how over 100 fourth graders did it this past Friday.

Step 4: Cut Paper

Never look at the sun. This projector is for use with your back to the sun.

Step 12: The Sun!

Picture of The Sun!

Looking at your shadow, aim the pin hole of the tube toward the sun. The pin hole projects the image of the sun right into the viewer. Look into the rectangular viewer hole to observe the sun and the eclipse! Remember your back is to the sun.

This is totally awesome as we can view the sun and the solar eclipse without worrying about hurting our eyes.
