The ‘Singing Pipe’ apparatus is a simple, effective and entertaining way to demonstrate energy conversion from heat (thermal energy) to sound energy. Quick and easy to set up and use, this demonstration rarely fails to impress. The apparatus consists of a 450 x 28 mm copper tube which has a metal gauze fitted inside, at a pinch point part way up from the base. The tube should be supported by a retort clamp towards the top, away from the heat, and a blue Bunsen burner flame directed into the base and onto the gauze for a few seconds only. Shortly after removing the flame, the tube emits a loud ‘foghorn’ sound as air is drawn up the tube by heat rising from the hot gauze. If the tube becomes too hot it will stop emitting sound, in which case it should be allowed to cool before trying again.
