History
Searching for exact temperature measurements.
Galileo Galilei discovered this fascinating method.
Galilei put 5 exactly weighted balls in a cylinder filled
with a special liquid.The balls go up or down according
to the existing temperature. By this method you can
determine the temperature.
Temperature indication
In liquid,a solid body with the same weight and size is
compelled to go down as the temperature rises,on the
other hand the solid body goes up in the liquid if the
temperature falls.The glass balls differ in weight and
floating balls in the upper part of the cylinder indicates
the right temperature.
