A Galileo thermometer (or Galilean thermometer) is a thermometer made of a sealed glass cylinder containing a clear liquid and several glass vessels of varying density. The individual floats rise or fall in proportion to their respective density and the density of the surrounding liquid as the temperature changes.
Termometr Galileusza (nazywany też termoskopem) – przyrząd służący do oceny temperatury otoczenia; odpowiednio wykalibrowany może pełnić funkcję termometru. Obecnie używany głównie w charakterze gadżetu, zabawki lub elementu sztuki użytkowej.

History. [edit] It is thought, but not certain, that Galileo Galilei discovered the specific principle on which the device is based and built the first thermoscope in 1593. [citation needed] In the 17th century Galileo mentioned to his friend Cesare Marsili that he invented a thermoscope as far back as 1606. [ 6 ]
Today, Galileo's invention is called the Galileo Thermometer, even though by definition it was really a thermoscope. It was a container filled with bulbs of varying mass, each with a temperature marking.
The thermometer is an instrument for measuring temperature whose development began in the early seventeenth century. Thermometers are based on the property of gases, liquids, and solids to expand or contract with changes in temperature. Other thermometer designs are based on electrical phenomena.
