Here's a classic science demonstration that is sure to grab your students' attention... and the people down the hallway... and every dog in the neighborhood! When you run your fingers lightly along this 60-cm-long metal rod, an ear-piercing sound is generated. You control how loud the sound gets, from a whisper to an auditorium-filling shriek. Absolutely incredible! This is a great experiment to demonstrate the difference between longitudinal and transverse waves. Each singing rod comes with instructions and a bag of crushed rosin to lightly coat your fingertips. Set of three consists of rods of lengths 60, 80, and 100 cm. Singing Rods no longer available. Only rosin available.
