Product Details

Singing Rods, 50cm and 75cm Long

by American Scientific


"Singing" Rods make a great addition to any teachers lessons about sound and waves. It's sure to grab the attention of every student in the classroom, as well as the people down the hall, and all the neighborhood dogs! You just have to know the secret to making the rods sing.

Simply hold the rod at one of the marked nodes using the thumb and forefinger of one hand, and with a little bit of rosin on the fingers of the other hand, pinch the rosin coated fingers around the rod near the hand holding it, and slide toward the end of the rod and off. Go back to the middle, pinch, and slide. Repeating this motion causes the sound grows from a quiet whisper up to an auditorium-filling shriek. Creating a pure and loud tone may require practice.

Perfect for teaching, and demonstrating, longitudinal waves rather than transverse waves, as well as nodes and anti-nodes.

Included is a small bag of rosin and two rods (50 and 75cm) with which the relationship between pitch and length can be explored. A teacher's guide with experiments is also included.
