A collection of eight tubes cut to the length for musical notes (from shortest to longest) C,B,A,G,F,E,D, and C with each note a unique color. There are also caps for each tube to change the end of the tube from an antinode to a node. A musical book is included which is color coded for each note.
You can sound the tubes by striking with the palm of you hand or striking an object such as the back of a chair.
Resonance can be shown by holding a tuning fork over the end of one of the tubes.
End caps can be placed over the end of the tube to change the note. A 512 Hz tube can be made into a 1024 Hz tube by placing an cap over one end.
