Intended Use
The product is used as a decorative solar lamp for gardens or terraces. The
solar panel integrated in the device charges the rechargeable battery during
the hours of daylight. The solar light switches on the light automatically when
darkness falls, and the rechargeable battery in the device provides the energy
for the light. During the day, the solar light switches itself off automatically.
The solar light is designed for domestic use, and is not for use in commercial
premises. Any use other than that described above is not permitted.
Galileo-Thermometer
Based on an idea by Galileo Galilei (1564-1642)
History
Searching for a way to measure exact temperatures, Galileo discovered this
fascinating method. He placed several exactly weighted balls in a cylinder filled
with a certain liquid. He found that the balls rose or fell according tot he
current temperature. By this method, he was able to determine the correct
temperature.
How it works
This thermometer works on the principle discovered by Galileo that the density
of a liquid changes as temperature varies. Each oft he glass balls is exactly
weighted by partially filling the spheres with liquid. When the temperature
rises, the liquid in the glass cylinder becomes less dense, and the heavier balls
sink slowly to the bottom.
How to read
The lowest temperature ball within the group at
the top of the cylinder tells the correct
temperature.
A. The lowest floating ball indicates the current
temperature.
B. If all the balls float to the top, the temperature
is below the lowest floating ball.
C. If all the balls sink, the temperature is above the
highest ball.
