In 2014, two teenage girls met at a summer coding program and created something extraordinary. Andrea "Andy" Gonzales and Sophie Houser developed "Tampon Run" - a game where players throw tampons at enemies instead of shooting bullets. What began as a coding project exploded overnight, reaching over half a million people worldwide and catapulting them into unexpected fame. Their creation wasn't just entertaining; it challenged one of society's most persistent taboos and sparked crucial conversations about menstruation stigma and women in technology. Most remarkably, they accomplished all this while still navigating high school, homework, and the complexities of teenage life. Their journey demonstrates how coding can become a powerful tool for social change, especially when wielded by young women determined to make their voices heard in spaces where they've traditionally been silenced.
