Can I tell you a secret? Ok, but you have to stand over there.. Explore the magic of sound waves at our Whisper Dishes or Tubes! At the whisper dish visitors stand just two feet away from the very center of the blue disk and whisper... your friend can hear you from the other dish! The same thing works on the super cool red tubes, whisper your secret on one end, and your friend will hear from the other! The secret is in the special shapes that reflect sound waves back, and concentrates them to the other side- making it sound like you and your friend are standing right next to each other!
