Before the invention of our modern-day music devices, our “ancestors” listened to music that was produced from mechanical motion. The concept of the CD player, and eventually the iPod, was developed from Thomas Edison’s original ideas about the mechanical reproduction of sound. Visit Glenwood Branch on Wednesday, March 10 at 7:00 pm to discover the science behind sound, and watch sound waves work. You’ll even make a phonograph to take home!
