Sound waves will not travel through a vacuum. Prove it with this demonstration of a ringing bell inside a sealed glass jar. As air is gradually vacuumed out of the jar, the bell will become faint, and will eventually become silent. Great demonstration model for the classroom setting.

Features:

  • Bell jar with bell and pressure plate
  • Demonstrates the inability of sound waves to travel through a vacuum
  • Excellent classroom demonstration model
  • Size: 8 inches diameter base, 8 inch tall glass dome
  • Requires standard 1/4 inch tubing

We boiled water, inflated a balloon, and could not heard the bell ringing under the vacuum with this bell jar.
