Kids build a simple robot hand using straws, string, and cardboard to explore how joints and tendons work. As they assemble and test their creation, they learn about engineering, biomechanics, and how movement is transferred through tension. It’s an engaging, hands‑on STEM project that brings science to life through play. Joan P. Garner Library at Ponce De Leon hosts this free Fulton County Library event in Atlanta, with 4:00 PM-4:30 PM.
