  • 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.
