s part of the Lights On Afterschool nationwide event, students in the 21C after school program at Rundlett Middle School built a Rube Goldberg Machine on Thursday afternoon. What’s that? According to rubegoldberg.com, it’s “an overly complex contraption, designed with humor and a narrative, to accomplish a simple task.” Students ran a ball down a ramp, through a stack of yogurt cups and into science books stacked like dominos, which tumbled down the line, with the last book falling onto a power switch and turning on a fan.
