Huh, but that's totally a tin can telephone. Would be a fun project for an experimental archeologist. The cans - I mean gourds - have little drumskin membranes stretched over them! The twine looks like the only dubious part, too stretchy maybe. Not sure what qualities an acoustic transmission line should have.

Make one out of gourds and see if it works.

If you have to yell in it, though, the other end can hear you 75 feet away just fine without it!

		Why would it not? The string/twine is more the key to it really, are you thinking the gourd would be too dampening? They do say it's resin-coated. I'm not saying I buy that that's what this was made for or how it was used, but I do reckon you can make a functional 'telephone' of this style with gourds.
