has anyone ever tried the soda bottle thing?

has anyone ever actually tried this? i was thinking of attaching some pieces of particle board using hinges, lining it with bottles like this... and then recording inside of that. i think that maybe sounds kinda ridiculous, but would this sound cool? has anyone tried anything dealing with using plastic and glass bottles like this?The helmholtz resonator (named after a Mr Helmholtz who discovered it) can best be demonstrated by taking a normal soft drink bottle and blowing over the mouth of the bottle - a note is produced. Now place some cotton wool in the bottle and try again. You will notice the note has reduced- well not really, the note is produced but the wool absorbs the resonance and turn the sound energy into heat! Imagine, if you lined a whole wall with bottles of various sizes, all filled with insulation material. You would now have a low-mid (200 - 500Hz depending on the bottle size) absorbing wall that as well as absorbing the low mids would also reflect or diffuse the high frequencies. I haven't tried it yet but it would be worth trying if you are short of cash because bottles are cheap.
do you even think it would be worth the effort?
