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