Harr began her Make a Stand organization in 2012. She set up a lemonade outpost and worked for days to raise more than $100,000, which she donated to the Not for Sale campaign. Make a Stand now contributes 5 percent of its revenue to what it calls a "mutual fund" of anti-slavery organizations.
But, why would Twitter choose her to represent them at the NYSE? Well, like Sir Patrick Stewart, Harr is big on social media. The invite was no surprise, but the fact that she physically got to ring the bell reportedly was. “Today, we rang the bell for hope and freedom, and I just would like to tell everyone out there that you don’t have to be big or powerful to change the world,” she told Ha. “You can be just like me.” (TechCrunch)
