About This Product
The bell jar experiment is a standard demonstration in school physics. A ringing electric bell is placed under the jar and the air is pumped out. As the air is removed the sound becomes fainter, which shows that sound cannot travel through empty space and needs a material medium. The glass jar is the chamber that holds the vacuum during the demonstration, and it should be handled with care because glass can crack under pressure differences. School Lab Equipment India can export the Bell Jar to education buyers in Peru, Seychelles, Argentina, Mongolia, Guyana and Zimbabwe.
