How to make a 3d (Red/Cyan) Glasses

1. Download and print off a copy of the PDF. This can be downloaded fromhttp://stereo.gsfc.nasa.gov/img/glasses.pdf, or enlarge the image provided here. Cut out each piece (including the eyeholes). Stick the sides to the center to form a pair of glasses. This forms a stencil.
   
   
   
2. 2
   Tape the stencil flat to the sturdy poster board, or trace around it. Cut out the glasses. Cut the eyeholes as well.
3. 3
   Cut out lenses from the sheets of blue and red acetate. If you can only find clear acetate, color with a red and blue marker (one red, one blue lens).
   • Make sure to cut the acetate pieces a little larger than the opening for the eyes.
4. 4
   Tape the lenses over the eyeholes. Red goes on the LEFT, and blue goes on theRIGHT.
   • Do not get tape on parts of the acetate visible through the eyehole.
