where colored liquid in a U-shaped section shifts measurably as air blown through a constricted glass tube creates pressure differences

producing the stroboscopic effect that visually freezes vibrating or rotating objects when the disc speed matches their frequency

illustrating the Lorentz force as current crossing the magnetic field sets a low-friction wheel in motion

25-inch base raises a magnetic needle to a 4

Magnetic Inclination Needle for Earth Field Demonstration Capacity_50mL 3 glass eudiometer tube withVertically pivoting magnetic needle that visualizes the dip angle of Earth's field, showing how inclination shifts from horizontal at the equator to vertical at the poles.
