NEW IN BOX Heebie Jeebies Hanging Galileo Thermometer 48cm

Material: Glass, contains paraffin oil
Measures: 48cm tall

This beautiful hand-blown glass Hanging Galileo Thermometer combines practicality with design, This amazing thermometer employs the principle of buoyancy and density. The body is filled with paraffin and air, which expands and contracts as needed - isolating it from air pressure.

The Galileo Thermometer uses paraffin as it responds to temperature changes quicker than water. As the temperature of the paraffin falls and becomes denser, the colourful baubles will rise and vice versa.

Each coloured bauble is carefully weighted so they will swap from floating to sinking at a particular temperature, giving you an accurate reading!

To read the Galileo Thermometer, simply note the lowest floating bauble in the middle. At extreme heat, all baubles will settle at the bottom, giving you the highest temperature and at extreme cold, all of the baubles will rise and the last bauble will give you the coldest temperature.

The 48cm Hanging Galileo Thermometer measures 16 degrees to 32 degrees.

A beautiful addition to your home and one that is a eye catching as it is useful!

How does it work?
Each one of the multi-coloured glass baubles is individually weighted, which means that when the ambient temperature changes, and alters the temperature and density of the paraffin inside the thermometer, the baubles rise and sink according to their density. The Galileo Thermometer is accurate between 16 degrees and 32 degrees, with the bottom bauble of the top grouping measuring the current temperature.
The temperature is indicated by a metal disc on the end of each bauble, allowing you to read the temperature. Galileo's Thermometer is based upon Galileo Galileo's discovery of buoyancy and density 400 years ago, so it is a fantastic way to teach science mad kids about new concepts. The principle of buoyancy determines whether or not objects rise or fall in a liquid, which is dependent upon the density of the liquid and the object placed within it. If the mass of the object is greater than the mass of the displaced liquid, the object will sink, and if it is less, the object will rise.
Galileo discovered that as temperatures increase, the density of liquid decreases. This is what allows the baubles to rise within the temperature's cylinder, and, as each bauble is weighted differently, they will either begin to rise or start sinking at a specific temperature. This then allows you to get an accurate temperature reading.

Add a charming and fascinating modern artefact as a display piece to your collection.
