Thanks for sharing this as I haven't come across UV beads before. I googled them and found: http://www.grand-illusions.com/acatalog/UV_Beads.html Is this the best place to get them? I think that this activity is a great way to combine "how science works" skills with teaching about UV. I have only given this 4/5 because I don't have enough UV lamps to do this as a class practical.
