I got my hands on 2 normal mirrors and would like to build a magic mirror. Even after extensive googling I couldn't find an answer.
I know normal mirrors have some reflective (metal?) and paint coating on them and was wondering if one could partially strip the coatings to create a one way mirror?
Another idea I had was to strip the coatings in very thin stripes with coating between them, think Scan Line Interleave but instead of a second image it's coating removed, not removed alternating. But I imagine one would need some serious kit to pull it off as DIY project because of the very small spaces between the lines.
I would love to hear your thoughts if it's feasible/practical or if I should just buy a glass (maybe acrylic) plate and put one way mirror foil on it.
