Bell Jar and Vacuum Activity Set |
| Use for a Variety of Vacuum and Air Pressure Activities |
The demonstrations feature the fundamentals of vacuum and air pressure as they describe the method by which a pump works and finding the mass and density of an air sample. You can show that a sealed balloon expands when the surrounding air is removed; a suction cup that is held on by external pressure, not “suction”; and that liquids boil at reduced temperature when under reduced pressure. The activity includes a bell jar, bottom plate, two hoses with check valves, a syringe (pump), two balloons, suction cup, and an instruction manual with copymasters for four experiments. Size: 3 1/2″H x 2 3/4 dia.
