What Is the Bell Jar Used For?
For vacuum work the jar stands on a flat plate connected to a vacuum pump, with a thin film of vacuum grease on the ground rim so that it seals as the air is drawn out. Classic physics demonstrations follow: a ringing bell that fades to silence as the air is removed, showing that sound needs a medium; a partly inflated balloon that swells; and warm water that boils at reduced pressure. Without a pump, biology classes use a bell jar to cover a potted plant in transpiration and photosynthesis experiments.
An evacuated glass vessel can implode, so check the jar for chips or cracks before each use, never evacuate a damaged jar, and use a safety screen in front of it. Let air back in slowly before lifting the jar off the plate, and wipe the grease from the rim before washing.
