All,
We are modifying our Sound Assembly. One demo connecting vibration and sound uses a 6' piece of latex tubing. The presenter holds one end under their foot and stretches it. When plucked the latex made a satisfying sound loud enough sound for the 150 kids to hear.
Now many schools don't allow latex in their buildings . We need to replace the latex with another material that will give a satisfying sound.
We have some purple tubing from a medical supply that does not make enough sound. No one remembers what it is .
Does anyone have suggestions on what kind of tubing would provide a sound louder than a deep thrum?
It has to roll up and stuff in a tub for transport.

Thanks for any suggestions.
