Isabelle and Katherine Adams are working in the playtime of others their ages--Isabelle is 9, Katherine is 6 (making her the youngest Giraffe ever). They're making and selling origami to pay for clean water wells around the world. These two tiny people have raised over $100,000 for that vital cause. They're now working on a kit for other kids who want to follow their lead. Read all about them at www.paperforwater.org.
