Well you could poke a stick at a goat, or a puppy... they are biology
that would make audible gas and other noises. There was that blue/GFP
rabbit... though I don't think rabbits make much noise, and while the
bulk of the work could be done in 2 weeks... you'd need a while for it
to gestate.

Chicken embryos are pretty cool, you could easily isolate the heart
and get chunks/cells growing in culture within a day or two... but
you'd need quite the microphone to hear the beating (maybe a piezo
microphone would work if taped directly to the culture dish?)... or
some software to convert a video of the beating heart cells into audio
(I bet this actually wouldn't be too hard with some openCV in Python
or something). But I guess simply dissecting something isn't really
bioengineering.

You could grow some yeast, trap the gas, then emit the gas through a
horn or harmonica... but again, simply growing something isn't really
bioengineering (at least in the media-popular mind).
