Wave & Sound
Bell in Bell Jar
Without air or matter, sound waves cannot travel and therefore cannot be heard. This bell jar effectively demonstrates this concept using a battery operated buzzer housed inside the jar. When the buzzer is placed beneath the jar and a vacuum is created inside the jar, students will observe a total absence of sound. Once the air is returned to the jar, the sound of the buzzer can be heard once more. The activity requires a vacuum pump & plate, not included.

Hand Vacuum Pump
The vacuum pump is made of durable plastic. It can easily provide a vacuum of 500mmHg by pumping its handle, the pumping rate of which is about 15ml per pumping. The pump itself is sealed and self lubricated. By changing its working mode, the pump can be used to establish air pressure as high as approx. 2 atm. It is a must for middle and primary school laboratories.
