We're following the lead of a six-year-old named Nora. When she heard that people die because of dirty water, she dug into her piggy bank, found $8.15, and mailed it to us. So we decided to show her how far $8.15 can go.

Today, we're asking you to follow Nora's lead. Give $8.15. Just $8.15. Just like Nora.
