25″ Tall Square Tube Galileo Thermometer With Wooden Base This is the ONLY Galileo Thermometer currently on the market that offers a SQUARE TUBE instead of a round one. Additionally, this unit display temperatures in both Fahrenheit and Celsius from 96 ˚f/34 ˚c – 56 ˚f/14 ˚c. With an oversize natural wood base, this Galileo Thermometer stands above the rest! 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. 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 56 ˚f/14 ˚c. If all the orbs sink to the bottom, the temperature is higher than 96 ˚f/34 ˚c. PLEASE NOTE: the stated height of 25″ 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. How does it work? Inspired by the finding of Galileo Galilei, these high quality glass thermometers demonstrate how temperature affects density and buoyancy. Each glass orb is partially filled with liquid to achieve a precise weight. A metal counterweight for each temperature is hung from the bottom of the orbs. As the temperature changes, the density of the liquid inside each orb changes, causing it to rise or fall within the column. Each thermometer is individually calibrated to achieve an accuracy of 2°. 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! 25″ Tall Square Tube Galileo Thermometer With Wooden Base This is the ONLY Galileo Thermometer currently on the market that offers a SQUARE TUBE instead of a round one.
