I'd give one a try but i would worry about the chemicals involved. I suppose if they weren't safe they wouldn't make them, but the chemicals needed for them to glow worry me a tad. Still, sounds like fun though!
It's almost pointless for me since to glow, glow in the dark items need to be in light. My toys are always stored away unless in use. But, I don't think it's weird by any means and would try them if the material was safer.
