Why not just use the UV beads?

Subject: [Astrolrner@CAE] UV exercise?
Must be summer, because I keep thinking of a million cool things to do in class (that I will likely never implement because it'll be crazy once the semester gets started!). Anyway, I was wondering if anyone had ever thought to do a UV light exercise with these:
They're little stickers you put on your baby when you go outside. When UV light has hit them, they change colors - first to yellow, then to red so you know to get to the shade. I thought they might make an interesting in-class exercise to see what sorts of materials block/don't block UV, or in a more advanced lab to find out exactly what these things are sensitive to. I don't want to reinvent a wheel, though, so if anyone's got anything like this, I'd love to see it. Thanks!
