This unit is an updated version of the Bell in a Bell Jar experiment. It
comprises a high amplitude, battery powered piezo sounder enclosed within a
clear acrylic tube. The sounder is controlled by switch and has a red LED
attached to show that it is on. By inserting the stopper in one end and
evacuating the tube using a standard laboratory vacuum pump, the air can be
removed and the effect of sound being unable to pass through a vacuum clearly
demonstrated. Dimensions: 110 x 90mm (Height x Diameter)
