Tucson Festival of Books

We’ve been a faithful supporter of this event since its founding in 2007. Initially focused on cleaning up after the festival, GLHN’s role has grown to staff the Mechanical Advantage booth in Science City where visitors are given the opportunity to learn about levers and fulcrums through the use of a giant yellow teeter-totter
