Here is a little background on constellations:
Constellations are "pictures" or arrangements of stars in the night sky. Similar to connecting the dots, you can "draw" images. These images made of stars are called constellations, and they often hold significant importance in our daily lives. For example, one of the stars in the constellation of Ursa Minor (the "little dipper") is the north star, and has been used in navigating on the sea for centuries.

You can skip the electrical part of this instructable by using a flashlight to illuminate the projector and provide the light.
P.S. We apologize beforehand that the cup we used was not a coffee cup. I did not have access to a cup when I made this instructable.
But now to start the instructable...
*This project was done with the help of legoguru4u (camera and knife work).
Step 1: The Materials
1 Paper coffee cup
1 White LED(Optional)
1 Toggle switch (Optional)
Battery Pack that holds 2 AAA or 2 AA batteries (Optional)
Constellation Templates (I recommend printing the templates on card-stock)
(See here: http://www.nestlefamily.com/Nirf/cm2/upload/EBC53EC4-EB35-4E09-B76B-551540583430/5.06.04_Whats_In_The_Night_Sky_tp.gif)
You will use:
Needle (type used for sewing) or a knife
Soldering Iron with Solder (Optional)
Step 2: Making a Slide
First, take the template and cut out the circles for the constellations. Then use the knife to poke holes in the circles where the dots indicate a star.
Step 3: Make the Projector
Next, cut a small hole closer to the base of the cup. This hole will be the placement for the switch, so make sure that the switch fits nice an snug.
Step 4: Electrical (Optional)
Step 5: Put It Together!
If you are using a flashlight, just point it upwards through the hole in the cup.
You are ready to go! Turn on the light and put a slide of the constellation you want on top.
