Step 1: Cut and fold the printout according to directions printed on it. (You might want two copies so that you can work with one while reading the directions on the other.) The only hard part is pushing the pencil point through the center of the small circle. It helps to twirl the pencil as you push.

During autumn and winter, the Sun shines up from below the readout face, and the shadow is visible through the paper.

Step 2: When you’re done, the pencil should be perpendicular to the sundial’s face (not to the base). If the pencil wants to topple over, try taping the whole thing to another piece of paper or (better) to a sheet of cardboard. Mounting the sundial on cardboard also makes it easier to carry around. Cereal boxes are a great source of free cardboard.

Step 3: Now turn the sundial so that the pencil points due north (or due south if you live in the Southern Hemisphere). You can use a compass or a map to determine the proper direction, or you can just orient the sundial so that it agrees with your local time. (Don't forget to subtract one hour from clock time if you’re on daylight-saving time.)

That's it! Now you can watch the shadow on the sundial change as the Sun moves from east to west over the course of the day.
