STEMroller events disrupt stereotypes surrounding STEM professionals within a neglected space in science communication; a sports hall. Roller derby inspired STEMroller, both the do-it-yourself culture and creating a space for women and genderqueer people to be themselves. Over 100 female and non-binary STEM professionals volunteered to put this event together for students aged 11–19. STEMroller includes networking with people from over 30 science, technology engineering and mathematics industries, watching roller derby and trying it out — albeit in socks not on wheels. STEMroller uses a pool of engaged volunteers to create a unique and memorable event. Feedback after the event was hugely positive.
