Pneumatic Demonstration Device
notes: label: Description
content: Alfred Payson Gage (1836-1903), a graduate of Dartmouth College, spent his career teaching high school physics, writing physics textbooks, and developing several successful pieces of demonstration apparatus. This is an example of his Multi-Purpose Pneumatic Demonstration Apparatus, or "Seven-in-One" apparatus, suitable for demonstrating fundamental principles of pneumatics and hydraulics. It served the purpose of a hydraulic lift, hydraulic press, incompressibility of liquids apparatus, Pascal’s law apparatus, pneumatic lift, hydrostatic bellows, and Magdeburg hemispheres.
