Description: | Glass cylinder filled with water; rubber diaphram on top fastened with metal jubilee clip; glass figure inside in the shape of a diver, half filled with water. When rubber cover is depressed firmly, pressure inside increases which decreases size of air bubble in the diver, allowing more water to enter and diver sinks to bottom because of reduced buoyancy; This is a classic demonstration, hard to date. The diver is very nicely figured. | License: | http://www.abdn.ac.uk/historic/Copyright_terms_conditions.shtml | Publisher: | ABDNP University of Aberdeen, Natural Philosophy Collection of Historical Scientific Instruments | Rights holder: | 47718 | Temporal: | 1920-1965 | Source: | University of Aberdeen | Identifier: | http://calms.abdn.ac.uk/Geology/dserve.e... | Go to resource |
