How do you make those 3D glasses?

How to make 3d glasses?

• i need to make red and blue 3d glasses without permanent markers. i also have glass paints and water colours any idea how i can do it

• Answer:

  The actual colors are magenta and cyan (reddish and greenish blue) and for the 3D to work properly they have to match closely otherwise they won't filter out the "wrong" image. Glass paints will be too opaque and water colors probably won't stick evenly to transparent surfaces like glass or plastic. For a rough match use blue and red cellophane used in floral arrangements - you can probably scrounge some from a flower shop by asking politely.
