This aluminum Singing Rod is great as an addition to your selection of sound wave demonstrations. With some practice you will be a musical wizard as you play this unique musical instrument. The comprehensive activity guide will teach you the right strategy for getting the perfect tone from the Singing Rod. Recommended for children ages 10 and up. Comes complete with three aluminum rods, 61 cm, 76 cm and 91 cm (24 inch, 30 inch and 36 inch), special rosin and fully illustrated science activity guide.
Also available: Single Singing Rod (WSNG-100).
- 3 Singing Rods in different lengths
- Illustrated science activity guide
How does it work?Get ready to make the Singing Rod sing! Collect a little rosin on your fingers. Grip the Singing Rod tightly at the midpoint and rub the Singing Rod between your thumb and first two fingers from its midpoint to the end. It may take a bit of practice, but you won't mistake the sound when you hear it! Move your stationary hand down the Singing Rod to the quarter point to make a higher pitch!
What does it teach?Learn where sound comes from—alternating condensations and refractions of the air surrounding the Singing Rod. Discover that Singing Rods of different lengths create different waves and frequencies. Use this fact to discuss nodes, anti-nodes and transverse standing waves. It's all in the science of sound!

This is my second set of these. Gave first set to a fellow teacher. I love them. However very disappointed in the shipping. Very poorly packed. First time I order the set the rosin was busted and had to send new bag. The new set I just received, the box was had big hole where rods punched through it. Just seems there would be more packing inside the box to prevent this.
Wow... get your ear plugs ready!!!

I ordered these for my Science class and was surprised by how loud they get. I had my students holding their ears as I demonstrated the rods at the front of the room. Students were amazed at how the sound was created and we related it to how dogs can sometimes predict earthquakes before humans because of the vibration causing a high pitched sound. Love to use the experiments as an attention getter for my Science lessons. Fun in the classroom put put your ear plugs in first...
Great for voice teachers

I'm using these in my voice studio to show how easy it is to get higher overtones. It's a really neat teaching unit; I combine it with a u-tube video on standing waves and a talking drum to demonstrate sound waves and air compression.

these are cool and great value as you get 3 different lengths of rod + rosin, others i've shown them too are also really impressed with them
