Bell in Jar with Air pump STEM Science Lab Demonstration Model

Product Code : SCL-SK-14282

The Bell in Jar with Air Pump is a classic physics demonstration apparatus designed to show how sound requires a medium for transmission.
It features an electric bell (operating on 4–6V AC/DC) suspended on a rubber cord inside a sealed bell jar.
Fine coiled wire connections pass through terminals fitted in a rubber cork, ensuring an airtight seal.

The entire assembly is mounted on a sturdy wooden base equipped with an integrated air pump, allowing users to gradually remove air from the jar.
As the air is evacuated, the sound of the bell becomes faint, clearly demonstrating the relationship between air pressure and sound propagation.

Ideal for physics classrooms, STEM labs, and demonstrations on sound waves, vacuum principles, and medium dependency.
