I got the idea for freezing THE towel from my best friend who went to the concert with me. She was like "I would freeze that towel as soon as we get home." I was like "Why?" She told me people use to freeze Elvis's towels to perserve the sweat. That way it didn't evaporate, you still have the real sweat on the towel. I laugh, but she convinced me to do it. I'm glad I did, because I got to thinking about it. I guess she is right!
