Nonprofit Paper for Water is helping to bring running water to those in need.

The organization, founded by 12-year-old Isabelle Adams and her 10-year-old sister, Katherine, makes and sells origami Christmas ornaments. So far, they've brought in $800,000 in water fundraising dollars.

In the video above, learn about how the organization helped a Navajo family living on a New Mexico reservation, where 40 percent of inhabitants don't have access to running water.

Clarification: The headline of this article has been updated to reflect that the $800,000 raised by Paper For Water was not the amount provided for the Navajo reservation, but rather is the amount raised in total by the group.
