O'BRIEN: That would be the Foo Fighters, "My Hero". This week's CNN Hero is a mother who turned unimaginable grief into joy. Take a look.</s>WANDA BUTTS, CNN HERO OF THE WEEK: Josh went to spend the night with friends. I had no clue that they were coming to the lake. Right about here is where Josh was, where the raft capsized and he went down. It's very hard for me to believe that just like that my son had drowned and he was gone. My father instilled in us the fear of water and so I in turn didn't take my son around water. Children don't have to drown. My name is Wanda Butts. I save lives by providing swimming lessons and water safety skills. Jacob Kendrick. African-American children are three times more likely to drown than white children. That's why we started the Josh Project. To educate families about the importance of being water safe.</s>UNIDENTIFIED MALE: Take the ring buoy and throw it at the victim.</s>BUTTS: Many parents they don't know how to swim.</s>UNIDENTIFIED FEMALE: He was afraid of the water. He is the first in my family to learn how to swim. And he's come a long way from not liking water in his face to getting dunked under.</s>UNIDENTIFIED FEMALE: You like it? All right.</s>BUTTS: I'm so happy to see that so many of them have learned how to swim. Good job. That's one life we saved. It takes me back to Josh and how the tragedy was turned into triumph and it makes me happy.</s>PEOPLE: Josh Project.</s>BUTTS: All right.</s>O'BRIEN: Good for her. I love that. "End Point" is up next with our panel. We're back in a moment.
