It All Started...

 

Large Groan Tubes

This instrument is found in a main hallway at Crotched Mountain Rehab Center. Passersby activate the sound by spinning the copper tubes. Each tube contains two "giggle sticks," pneumatic sound generating toys generally found in party stores. The sound is both humorous and engaging. It has been played thousands of times by students and staff at the facility.
