What is it?

My Granddaughter just arrive home after serving one year in Korea with the Army.  She is staying here until she goes to her next assignment in a few days.  Yes, her things are set in certain spots in the house.  At least they aren't scattered all over.  I went into the bathroom and found this thing, I would say it was a hair brush, at least it looked like one.  It was loaded with her hair!  It was unbelievable that that much hair came out of her head!  She has fine hair.  Of course I had to go and ask her what it was.  We all had a good laugh.  But now the more I think about it, we can turn this into something else.  There are people out there that save dog and cat hair and make knitted sweaters, maybe we can send this brush to them and they can knit a sweater out of it!  I will go buy a brush just like it and make a switch.  Think she'll notice?....
