Bell jar with battery operated buzzer
Stock Code:
PH0178
Unit:
Each
Price:
$79.00 (ex GST)
Description
This basic bell jar experiment kit effectively demonstrates this concept of sound in a vacuum using a battery operated buzzer housed inside an acrylic housing.
When the buzzer is placed beneath the jar and a vacuum seal is created in the chamber, students will observe the sound levels dimishing. Once air is returned to the chamber, the sound of the buzzer can be heard once more.
Dimensions: 14cm high, 10cm diameter
