Has anyone tried the stretchy stuff in the bag? Does it glow naturally under a blacklight? Would it work soaking it in the Rit Whitener/Brightener? Just wondered if anyone has tried that. I was going to cover the house in webbing and have a couple of large webs made out of clothesline that was soaked in the Rit. My house is a light color so passersby could see the light colored webs during the daytime, but then I was hoping to make it all glow at night when the UV light kicked on. Thanks!
