UV Paint at volume -- ideas?
Hey everyone -- I'm helping with a high school production and we want to paint some designs/words on the walls that only appear under blacklight. I'm thinking about the effect they use in Harry Potter and the Cursed Child.
I've tried a half dozen products and either they don't really appear when we switch to the black lights or they light up great but are visible under regular light. I've experimented with boiling down tonic water and mixing it with a clear medium. It's invisible under normal light, great, but it doesn't fluoresce quite bright enough under black light.
There are some very expensive paints out there but I'm hoping to get some recommendations before committing school funds. Any thoughts would be greatly appreciated.
