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 densities.
As temperature changes, the individual floats rise or fall in proportion to their respective density.
This thermometer has coloured liquid floats with the temperature ranging between 16 and 28 degrees Celsius.
The coloured floats have gold coloured tags stating the temperature.
