Resonance, Sound & Waves

Strike up the band and demonstrate resonance, interference, pitch, and harmonics with these fun products. Appropriate for both instructional purposes or as part of a larger marching ensemble! Insightful, fun and sometimes loud; rhythm not included! When tossed in the air, Buzzing Stunt Magnets produce a clattering sound, much like a Cicada or high voltage sparking. Heat one end of the Singing Pipe to produce a loud tone, then "pour" the sound into a beaker. Amazing! When your fingers are slid repeatedly along the 60-cm-long Singing Rod, an ear-piercing sound is generated. You have to hear it to believe it! When spun in a circular motion, Sound Tubes produce a tone. As they are spun faster, the tone steps up in frequency.
