The Galilean thermometer is a handsome, novel and practical
glass thermometer for decoration. With the function of both
temperature display and interior decoration, it is suitable
for use at home, in the office, hotel ,meeting room, etc.
It is an environment friendly product composed of a tubular
glass container, colored balls with temperature tags, and
inert liquid. Inside the balls is the nontoxic colored
liquid, and the tags are of gold plated alloy. Its
principle of work is:making use of the sensitivity of the
buoyancy and tension of liquid to the temperature changes
as well as the difference of specific gravity of liquid
under different temperature.

In the glass tube is the temperature sensitive liquid while
the colored balls are insensitive ones. When thermodynamic
activity occurs to the liquid inside the tube due to the
temperature change, the balls rise or drop accordingly,
among which the reading on the metal tag of the lowest
floating is the current environmental temperature.
