IMPORTANT INFORMATION ABOUT THIS PRODUCT: Your sealed Galileo thermometer is filled with a common mineral-based, ozone friendly solvent (paraffin oil) to prevent bacterial growth. In case of breakage, keep away from any ignition sources as it is highly flammable. Ventilate area immediately and absorb the liquid with disposable towels. Wash hands with soap and water. Potential eye irritant! In case of ingestion contact your local poison control center immediately. Be sure to use care when cleaning to avoid injury. This item requires no special disposal procedures and is made entirely of Earth friendly materials! The barometer portion will arrive empty and you must fill it with distilled water. We suggest using food coloring to change the color of the water. It comes with a small hose and syringe.
What is a Galileo Thermometer and how do I read it?
A Galileo Thermometer is a sealed glass column containing multiple liquid filled orbs. As the temperature changes, these orbs rise and fall to indicate the current ambient temperature (within the range of 64˚F - 80˚F). Under normal conditions, the orbs will settle into two groupings toward the top and bottom of the glass column as shown to the left. To read the Galileo Thermometer, observe the metal tags hanging from each orb. The tag on the lowest orb in the top grouping displays the current ambient temperature. If all the orbs float to the top, the temperature is below 64˚F. If all the orbs sink to the bottom, the temperature is higher than 80˚F. PLEASE NOTE: the stated height of 13" is only an approximation. This item is finished with a hand process that creates a varying finished height, which may be slightly higher or shorter than the stated height.
What is a Goethe Weather Ball Barometer?
A Goethe weather ball barometer is a device that predicts barometric weather changes by observing the rise and fall of liquid within the spout of a vented glass vessel. A low water level in the spout suggests “high pressure”, representing fair weather. A high water level in the spout suggests “low pressure” and forecasts poor weather conditions. While it will not indicate exact barometric pressure in numerical values, it is still regarded as an accurate monitor of air pressure changes.,
