Maybe the seal isn't perfect, or maybe its going through the solids...like through the stand and the base of the vacuum itself...idk, that's just a thought.
very nice. an improved version would be to evacuate air completely, and have a CO2 capsule inside the jar and to trigger that capsule to fill the jar from the inside, so no noise of any kind would be heared before the jar starts to fill
Way to think outside of the box. Or better yet inside of the jar. Hey I was wondering that maybe it isnt that its not traveling through the vacuumed air as well as it is just hitting a higher or no autible frequency through the vacuum. Please let me know what you think. It would be nice to have a gauge that can pick up higher autible frequency. Thanks. Keep up the science.
Sound has to have some medium to travel through. In a vacuum there simply can't be any sound. Most science fiction movies ignore this inconvenient fact.
@mlchiLCA You misunderstand the science behind this. Sound waves are simply ripples in mediums. Producing sound waves in a vacuum would be like throwing a pebble onto the ground and expect it to produce water ripples. There's no water, ergo no ripple. Similarly, no medium in a vacuum -- no sound waves produced.
Science fiction movies LISTEN UP!

i think the sound traveled throught the object that holds the bell :<

There's no such thing as a perfect vacuum. Therefore, there will still be some amount of propagation.

could do with some help here? Describe how the effect a vacuum has on the ability of a sound wave to travel in it.

Sound = Longitudinal waves...gotta remember the definition of it..5D

@teralabUK
thats by our standards...maybe it does travel at a frequency that earthly beings cant hear nor gauge with current technology
