Get one of those little sound amplifiers at Radio Shack.(I own two
models of them) They look sort of like tiny transistor radios and you
have to use ear buds or ear phones with them,they do not have a built in
speaker.Put the device inside of a sock and stick it between one of your
leg joints near your hip and your belly.You will hear some very,very
strange sounds indeed,coming from your stomach guts.
