OPERATION
Galileo Thermometer
When temperature rises, the liquid inside the glass thermometer becomes less dense
and the liquid-filled bulbs will sink. When the temperature drops, the liquid inside the
thermometer becomes more dense and the liquid-filled bulbs will float.
Temperature
A. The temperature is determined by the lowest floating bulb in
the thermometer.
B. When there is a bulb in the middle, the temperature is between
that degree and the lowest floating bulb.
C. If all the bulbs float to the top, the temperature is under the
lowest floating bulb.
D. If all the bulbs sink, the temperature is over the highest bulb.
Storm Glass Barometer
Variations in barometric pressure are associated with changes
in the weather. The Storm Glass barometer accurately forecasts
changes in the weather hours in advance because the water level in the spout of the
Storm Glass reacts to changes in the atmospheric pressure.
A low water level in the spout indicates HIGH pressure, and fair weather can be
expected. A high water level in the spout indicates LOW pressure, and precipitation can
be expected. In cases of severe weather or major storms the water may even run out of
the spout.
The Storm Glass does not indicate exact pressure, like a numeric barometer, but it is
accurate enough to display the change in air pressure between the basement and attic
in the same house.
