Singing Glasses Toothpick Mover

Challenge your learners with a film on sound and vibration. Two wine glasses are filled with water and are then used to make sounds. When water is added to the glass, or removed from the glass, the pitch of the sound changes. Then, a toothpick is placed on a glass and vibrations cause it to meander across the lip. What a terrific way to introduce the concepts of sound and vibration.
