Extra-loud noise maker that makes a range of strange rumbling sounds. With the spring-like end facing downwards, start moving the tube from side to side. As the spring moves, it reverberates sound up into the tube that then produces some impressive rumbles. Experiment with different movements to get different sounds. It's so unusual in nature, that this is a particularly effective demo line.
