How can washing your hands help give a child clean water to drink? When you use Noodle & Boo’s Believe Honey Bar ($12.50) to do it. The company will funnel 100% of the profits from sales of the soap to its Raise Your Hand Campaign, which works to fund water-purification systems one village at a time. Efforts will first focus on Heeraraa, a small village in Ethiopia with a school of 200 children. So go ahead and work yourself into a lather—it’s for a good cause.
