The faster you spin it the higher the sound! Science and sound has never been more hands-on than now with the fun 5 tone Sound Tube! Manipulate the sound waves and frequencies as you start swingin' the sound tube. The faster you spin it, the higher the sound. Get your arm swingin' and change the speed to hear up to 5 various tones. You can also blow into it to hear the tones.

 What you'll get:

• One 5 Tone Sound Tube (comes in assorted random colors).
  

Incredible Science Fun Learning Ideas:

• Learn about sound waves, frequencies, wavelengths and Hz in this fun, hands-on science experiment.
  
• Learn about fluid dynamics and Bernouilli's principle. As you swing the hose, there is higher pressure in the part that you are holding versus the swinging loose end. The higher pressure sucks in the air which creates the various sounds you hear.
