The University College London placed a tray of jello in the shape of St Paul's cathedral in an anechoic chamber and recorded the sound it made when it wobbled.
Sound artist Douglas Murphy, who recorded the sound says: "It is refreshing to explore the sonority of a much neglected physical property: the wobble factor. Jelly entices us into a strange but compelling world of organic sounds. The sonic wobble is captured in two ways: by carefully recording the results of gentle coaxing and by expressing the wobble frequency as physically powerful base tones."
