Superbowl 3D glasses - congo blue? Answered
Remember the 3d glasses that everyone got for the commercial Monsters vs. Aliens during the Superbowl this year (09)? They were paper, blue colored, mnfctrd by Intel, and the "lenses" were amber and some kind of dark blue.
What I was wondering was if that blue was Congo blue (LEE C181, like in Kipkay's IR goggles ible), so I could use them in making nightvision goggles.
