When Eric Harr was a kid, he made $9 one day from selling lemonade. He thought that was totally cool. Thirty years later, his daughter Vivienne set up a lemonade stand ... and did considerably better. Over 173 consecutive days, she took in $101,320. Vivienne, a 10-year-old with a penchant for bouncy princess dresses and the color pink, had a motive. Alarmed by photos she'd seen of Nepalese children hauling enormous rocks down a mountain, she decided in May 2012 to raise money to stop child slavery. When people stopped at her lemonade stand to ask how much she was charging, Vivienne said, Whatever's in your heart." She donated the $101,320 to Not for Sale, a nonprofit that works to eradicate human trafficking around the world. But she wasn't finished. During the last year and a half, her campaign morphed into a corporation. Make a Stand Lemon-Aid, which her father oversees, sells fair-trade, organic lemonade at 137 stores and is expected to gross $2 million this year. Along the way, Vivienne became a bit of a celebrity. In November, she joined "Star Trek" actor Patrick Stewart to ring the opening bell for Twitter's IPO at the New York Stock Exchange - a distinction bestowed because she and her dad, a social-media professional, had made extensive use of the microblogging service. In a new documentary, "#Standwithme," Portland, Ore., filmmakers Patrick Moreau and Grant Peelle show how Vivienne and her parents were drawn to their cause and set their story in a larger context of global efforts to halt human trafficking.
