Description:
The experiment “tambourine blows out candle" demonstrates clearly how sound waves propagate and that a movement of air particles is associated with it (you may use a bass drum instead of a tambourine). On the basis of this experiment the propagation of sound when speaking can be explained.

Information and ideas:
Simple experiment that can be reproduced easily in class.
