Singing Rods - 3 Tone Set

Product Information
Deluxe three rod demonstration set. Here's a classic science demonstration that is sure to grab your students' attention! The set comes with 3 aluminum rods of differing lengths. The motion of repeatedly sliding your hand down the bar (smoothly and gracefully) will cause the metal bar to resonate a high pitched sound. The key is to make as little contact with the rod as possible so as not to dampen the vibrations. Each rod gives a different tone. Great way to introduce the concepts of sound, wave or frequency. Includes: three aluminum rods (24", 30", 36"), special rosin and activity guide.
