Sup tokers, I'm making a blacklight rooms, so far ordered: - blacklight tubes (and fittings) - glow in the dark stars and shapes I need some cool blacklight posters, but they seem to be lacking where I'm from (UK), anybody know of any good UK sites where I can get them cheap? If not what exactly causes blacklight posters to react to the UV light? Is it literally just the colour or do the colours need to be printed on the poster in special ink? I'll post pics once its all set up
