This prism is made using optical glass and will demonstrate that white light is made up of the colours of the rainbow. This is known as a spectrum. In the 17th century Sir Isaac Newton was the first to prove that white light was in fact made up of different colours. He used a glass prism in his experiments. The prism is 5cm (2 in) long. Each side is about 2.5 cm (1 in). In opti..

Historic water glass. This simple barometer responds sensitively to changes in atmospheric pressure, through the water in the column. A high level indicates declining air pressure, a lower status is rising air pressure. The water should be in a place with constant temperature, because otherwise the change of temperature influences the column height. The barometer is ca. 22 cm high. The conc..

In the 17th century Galileo discovered that liquids change density with temperature. As the liquid in the frame is warmed or cooled by the air around it, the coloured globe inside rises or sinks as their relative density varies, indicating room temperature according to the printed scale. Measures 5" square. ..
