When sisters Isabelle and Katherine Adams were only 5 and 8 years old, their dad showed them the intricate paper folding techniques of origami. About that time, a friend told them that girls in poor countries sometimes can't go to school because they must carry water all day because of lack of wells. The sisters knew they had to help. So they founded "Paper for Water," selling origami ornaments to raise money. They dreamed of raising $200 toward the $9,200 needed to sink a well in Ethiopia by selling origami in Starbucks.
Within two months they raised $10,000 for the well, and that was just the beginning. Their hobby became a passion, and in the past seven years they have sold enough origami to create 160 water projects in 15 nations. So far, they've helped about 48,000 people have clean, accessible water.
