A Portable Detector for Cosmic-Ray Muons

University of Delaware physicist Spencer Axani developed CosmicWatch to make particle detection compact, affordable, and accessible. This video explores how the detector records cosmic-ray muons, helps students learn electronics and data analysis, and supports experiments beyond the classroom. Follow a student-built detector on a balloon flight reaching 100,000 feet to investigate how particle rates change with altitude.
