I've tried the secret markings on credit cards and know it works :) Trust me, it does.

That's a waste of money, but a good idea. Just dump an old highlighter cartridge in a bit of bubble solution.

Fluorescent black lights are around 370nm, far more purple than blu-ray.

^^ was just thinking of tonic too... quinine being the culprit for its UV reactive properties.
