Fifteen-inch enlarged spermatozoon model exposes the head
the shared mass isolating volume and density as the distinguishing variables across metals and polymers
Designed for liquid-fill Snell's-law work at smaller scale
but is an ideal choice for science classrooms and household use
holding volume constant across specimens for isolated density comparisons
Sonometer Pickup Material_PVC Fifteen-inch enlarged spermatozoon model exposesElectromagnetic pickup that converts sonometer string vibration directly into an electrical signal, allowing waveforms to be plotted on an oscilloscope or fed into a frequency analyzer.
