Vacuum Sound Accessory

Description

What happens to something that is vibrating when there's no air (or other medium) to transmit those vibrations? This simple accessory kit answers the question in dramatic style. Contains all the parts needed to build a small, powerful buzzer assembly that can be used with our Microscale Vacuum Apparatus (VAC-10/VAC-16). A memorable demonstration of the transmission (or NON-transmission) of sound in a low air pressure environment! Some assembly required.
