DUAL�WEATHER STATION
A TRADITIONAL WAY TO READ THE TEMPERATURE AND PREDICT THE WEATHER
Two historical devices in one. �Assembled size: 17.5 x 14 x 7cm
Storm �glass
Once used by seafarers to �predict oncoming storms, the storm glass barometer came into general use in the early 1700s, and responds to atmospheric fluctuations to forecast the weather. Admiral Robert Fitzroy conducted a detailed study of this instrument between 1834 and 1836. He refined the chemical formulation and published observational guidelines on how to predicy the weather, see instructions inside.
Galileo �Thermometer
In 1593, Galileo Galilei discovered that the density of liquids reacts predictably to changes in temperature. He invented a device that allowed temperature variations to be measured.
HOW IT WORKS
The sealed glass cylinder contains five floating glass bulbs. Each bulb has a calibrated, weighted metal tag. The temperature is determined by the lowest floating bulb. When there is a bulb in the middle, the temperature should be read as between this degree and the lowest floating bulb.
Temperature range: 16-32°C
