About This Product
The experiment demonstrates that sound is a longitudinal wave that needs a material medium to travel. The electric bell rings inside the sealed jar while the vacuum pump removes the air, and the sound grows fainter until nothing is heard. A Magdeburg hemisphere is also supplied with the set. The Bell Experiment is available for supply within the United Kingdom and for export to Serbia, Philippines, Democratic Republic of the Congo, Bahrain and Venezuela.
