You could always wash the sunscreen off, make a wreath or other art project, and spray paint it.I was saving mine but they faded so much they would not make a pretty wreath or chain. I don't know if it is my sun screen or body lotion because it seems like some people's magic bands fade a lot and other people's don't.
Saw a cute pic last year of someone that made a Christmas wreath out of their old ones.
