SANTA CRUZ -- The Fairfax girl who became a sensation after raising $100,000 from her lemonade stand to combat child slavery will be at the New Leaf Community Markets holiday craft fair in Santa Cruz on Saturday.

Vivienne Harr, a 9-year-old activist who has used Twitter to promote her lemonade stand and raise awareness about child slavery, is the subject of a new documentary, whose trailer was released Wednesday. The feature-length film, "#standwithme," follow's Harr's year-long effort and exposes the realities of modern child slavery.

Harr's roadside lemonade stand has evolved into Make a Stand, an organization that is largely run by her father, Eric Harr. Make a Stand raises money for nonprofits that work to end human trafficking and sells bottled lemonade in Bay Area grocery stores. Vivienne Harr's latest moment of stardom came last month when she was invited to help ring the New York Stock Exchange's opening bell on the morning of Twitter's initial public offering.

The New Leaf Community Markets craft fair is from noon to 4 p.m. at 1101 Fair Ave.
