Rotating Table Pulsar

Models a pulsar's lighthouse effect using rotating flashlights. Students learn that pulsars emit continuously but appear to pulse because their beamed radiation sweeps past Earth's line of sight — a …

Red Giant

Illustrates the dramatic size changes during stellar evolution using scaled physical objects: a 1-meter weather balloon (red giant), a marble (Sun), and a ballpoint pen tip (white dwarf). Students see …

Motion in Interstellar Clouds

Pepper sprinkled on freshly poured water exhibits random motion that quickly organizes into coherent rotation, modeling how interstellar gas clouds develop net angular momentum from initially disordered motion. Illustrates the …
