All you need for this is a record, needle, paper, pen, tape and wooden skewer. Question: Why can't the sound be heard from outside on the turntable we made with skewers and needles? a) Because there is no speaker that reflects sound to the outside like a cone b) Because we fix the skewer and needle with our mouth Answer: a) Because there is no mechanism that reflects sound to the outside like a cone
