Decorative Galileo Thermometers.
Galileo (1564-1642), one of the 16th Century's most renowned Renaissance scientists discovered that as the temperature of a liquid increases, it's buoyancy decreases. His findings were translated into an attractive, sealed glass thermometer containing a non-toxic Liquid with coloured floating spheres. The spheres are weighted to an accuracy of 3/1000 gram.
These handsome thermometers use the Archimedes Principle to measure temperature.
As the temperature of the air outside the thermometer changes, so does the temperature of the water surrounding the bubbles. As the temperature of the water changes so does its density. At any given density some of the bubbles will float and others will sink. The bubble that sinks the most indicates the approximate current temperature.
The instruments Latin name is Thermometrolento which means Slow Thermometer.
Look for the lowest floating sphere, this will give you the current room temperature. Available in three sizes 280mm, 330mm and 440mm, multi-coloured with five or seven spheres. These

Medical Thermometers
Glass thermometers containing Mercury are not generally considered to be the best to due to safety concerns as Mercury is highly dangerous. If you have one then consider replacing it with a digital electronic thermometer.
Digital electronic thermometers are accurate, easy to read.
Ear and forehead thermometers are ideal and easy to use either at home or in a clinical or medical practice. Thermometers are also available for oral, rectal and arm pits.
Alternatively temperature strips for the forehead are very convenient and safe but are not as accurate as digital thermometers. They are cheap but can only be used once per strip.
