Create 3D glasses (Red and cyan)

1. 1
   
   Find a cheap pair of plastic sunglasses. Dollar store or thrift store ones are perfectly fine, or you can find them in the kid's toys section. Pop out the plastic lenses.
   
   
2. 2
   
   Use the plastic lenses as a template to draw the correct shape onto the transparency sheet, cellophane, or acetate.
3. 3
   
   Cut out the lenses on the inside edge of the line you have traced on the plastic.
4. 4
   
   Color with the red and blue markers. If you didn't use red or blue colored plastic sheeting, you'll need to color each lens. Make one lens red, the other blue.
5. 5
   
   Place the colored lenses back into the frames. Red goes on the LEFT, and blue goes on the RIGHT.
6. 6
   
   Check that they fit well. Make any adjustments needed. Then start watching your 3D movie.
