it removes the tough stains that bleach doesn't and it also disinfects. that's healthing. and now it's time for "the mix." really amazing story here. last year, 11-year-old lost her pregnant mother and two sisters in a car accident. she also suffered some severe head injuries. part of her skull had to be removed. while she was severely hurt. but at her hospital, doctors have been able to treat her using music to help her beat the odds. so every night nurses play for her a little bit of bruno mars. >> oh, you're kidding. >> so now she found out that she'll be able to go to a bruno mars concert. really remarkable stuff. i think we have some sound of her actually finding out. >> oh, is that her? >> actually, this is her at the concert, being serenaded by her hero.
