Bell in Bell Jar

Product Code : JC-SL-4794

The bell in bell jar (SKU JC-SL-4794) shows that sound needs a material medium to travel. An electric bell working on 4-6 V AC/DC hangs from a rubber cord inside the jar, and coiled wires connect it to terminals fixed in the rubber bung that seals the jar. As air is pumped out through the vacuum pump plate, the ringing fades although the bell is still seen working.
