Three thousand years ago, a civilization ruled the Andes Mountains of South America. Not much is known about this pre-Incan civilization, but we do know beautifully decorated conch shells were played like musical instruments and used as parts of religious ceremonies. Now archaeologists and acousticians have teamed up to figure out what the shells sounded like and what purpose they served. Check out the video to see what they discovered, and you can find out more in the Stanford Report.
