It became scientific when the French savant, Blaise Pascal, discussed it in his <i>Treatise on the Equilibrium of Liquids</i> (1653). In time, simple hydrostatic instruments became popular for classroom demonstrations, and these instruments became known as Pascal vases. This example may date from the early nineteenth century."}, {"label": "Location", "content": "Currently not on view"}], "creditLine": [{"label": "Credit Line", "content": "Gift of Department of Defense, U.S. Military Academy"}], "physicalDescription": [{"label": "Physical Description", "content": "glass (overall material)"}, {"label": "Physical Description", "content": "brass (overall material)"}, {"label": "Measurements", "content": "overall: 15 3/4 in x 7 1/2 in; 40.005 cm x 19.05 cm"}, {"label": "Measurements", "content": "overall: 18 1/8 in x 10 7/16 in x 7 1/2 in; 46.0375 cm x 26.51125 cm x 19.05 cm"}], "dataSource": [{"label": "Data Source", "content": "National Museum of American History"}], "objectType": [{"label": "Object Name", "content": "hydrostatic apparatus"}]}}, "url": "edanmdm:nmah_1761412", "hash": "96e76b158240da17c682f366a2acdccae7b405b7", "docSignature": "354c388798ca8a51afa7d1ac2515d3a6", "timestamp": 1663336903, "lastTimeUpdated": 1653680688, "title": "Hydrostatic Apparatus"}
