Appreciated for its robustness, Fortin's barometer was used, together with the thermometer, in late eighteenth-century laboratories for accurately measuring the "atmospheric" conditions of experimental processes. The spheres also contain liquid, but it changes density much less rapidly than the clear liquid in the thermometer, so it isn’t affected by the temperature change. Their benefits go beyond helping you prepare proper clothes or improving the quality of indoor plants. Details of the thermometer were published in the Saggi di naturali esperienze fatte nell'Academia del Cimento sotto la protezione del Serenissimo Principe Leopoldo di Toscana e descritte dal segretario di essa Accademia (1666), the academy's main publication. The thermometer consists of a glass tube filled with a clear liquid, in which colored glass spheres float.

IMPORTANT INFORMATION ABOUT THIS PRODUCT: Your sealed Galileo thermometer is filled with a common mineral-based, ozone friendly solvent (paraffin oil) to prevent bacterial growth. Our distinctive ornamental (but functional) thermometers utilise 17th century astronomer Galileo Galilei's discovery that the density of liquids varies with temperature.
As the temperature changes, the multi coloured floating globes RISE and FALL within the liquid filled thermostatic tube.
A Goethe weather ball barometer is a device that predicts barometric weather changes by observing the rise and fall of liquid within the spout of a vented glass vessel.The top part of the tube holds a container, possibly for ice to minimize the pressure of the mercury vapor.
A lovely conversation starter and a fun example of early scientific measurement, this Galileo thermometer and Glass Barometer set from Lily’s Home engages the eye while monitoring the weather.What you have to do is simply look at the lowest ball that is floating while ignoring those tags that had sunk to the bottom of the container. jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"
