I had a $1 pack of light up bracelets and I cracked them tonight to use for a photo. I took several photos, none I was super happy with, but this was one of the best of the bunch. At some point one of them started leaking...eek! Also, I remember going to a festival on the Owensboro, KY riverfront as a kid and wanting these. Back then, just one cost $4. My, my how times have changed!
