Specification AgeRangeDescription : Adult BatteriesIncluded : 1 BatteriesRequired : 1 Brand : Palais Essentials BulletPoint1 : This gorgeous Galileo thermometer is a work of art with blown glass balls of varying colors in a delicate blown glass cylinder BulletPoint2 : The glass balls rise and fall within the liquid-filled cylinder to reflect changes in the temperature, and each ball has a small charm to read the temperature BulletPoint3 : Attached to each bubble is a little metal tag that indicates a temperature. These metal tags are calibrated counterweights. The weight of each tag is slightly different from the others BulletPoint4 : The Galileo thermometer consists of a sealed glass tube that is filled with liquid and several floating bubbles. The bubbles are glass spheres filled with a colored liquid mixture BulletPoint5 : As the temperature of the air outside the thermometer changes, so does the temperature of the liquid surrounding the bubbles. As the temperature of the liquid changes, it either expands or contracts, thereby changing its density CareInstructions : Hand Wash Only Color : Clear CustomerPackageType : Standard Packaging ExternallyAssignedProductIdentifier : 5060635641059 ExternallyAssignedProductIdentifier1 : 643307653007 ExternallyAssignedProductIdentifier2 : 0643307653007 ExternallyAssignedProductIdentifier3 : 00819137022355 Hazmat : 3 Hazmat1 : LITHIUM ION BATTERIES PACKED WITH EQUIPMENT Hazmat10 : CN_SmallLithiumIonBatteryWithEquipment Hazmat11 : DE_SmallLithiumIonBatteryWithEquipment Hazmat12 : EG_SmallLithiumIonBatteryWithEquipment Hazmat13 : ES_SmallLithiumIonBatteryWithEquipment Hazmat14 : FR_SmallLithiumIonBatteryWithEquipment Hazmat15 : GB_SmallLithiumIonBatteryWithEquipment Hazmat16 : IN_SmallLithiumIonBatteryWithEquipment Hazmat17 : IT_SmallLithiumIonBatteryWithEquipment Hazmat18 : JP_SmallLithiumIonBatteryWithEquipment Hazmat19 : MX_SmallLithiumIonBatteryWithEquipment Hazmat2 : UN3481 Hazmat20 : NL_SmallLithiumIonBatteryWithEquipment Hazmat21 : PL_SmallLithiumIonBatteryWithEquipment Hazmat22 : SA_SmallLithiumIonBatteryWithEquipment Hazmat23 : SE_SmallLithiumIonBatteryWithEquipment Hazmat24 : SG_SmallLithiumIonBatteryWithEquipment Hazmat25 : TR_SmallLithiumIonBatteryWithEquipment Hazmat26 : US_SmallLithiumIonBatteryWithEquipment Hazmat27 : ZA_SmallLithiumIonBatteryWithEquipment Hazmat3 : II Hazmat4 : 9 Hazmat5 : AE_SmallLithiumIonBatteryWithEquipment Hazmat6 : AU_SmallLithiumIonBatteryWithEquipment Hazmat7 : BE_SmallLithiumIonBatteryWithEquipment Hazmat8 : BR_SmallLithiumIonBatteryWithEquipment Hazmat9 : CA_SmallLithiumIonBatteryWithEquipment ImmersionDepth : 17.0 inches IncludedComponents : Batteries IndoorOutdoorUsage : indoor ItemLength : 15 inches ItemName : Palais Essentials Galileo Thermometer - Floating Glass Balls Fahrenheit Temperature Indicator - Fun and Decorative (17.5" Inches High, 10 Multi Colored Spheres) ItemPackageDimensions_Height : 48.26 centimeters ItemPackageDimensions_Length : 10.16 centimeters ItemPackageDimensions_Width : 10.16 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : indoor-thermometers LowerTemperatureRating : -10 degrees_celsius Manufacturer : Palais Essentials Material : ABS MeasurementAccuracy : +/- 0.5% ModelNumber : 200600LL37qQ46Rq40O71 MountingType : Tabletop NumberOfItems : 3 OperatingHumidity : 10%~99% RH PartNumber : HE-P-1503 PowerSourceType : Solar Powered ProductDescription : The Galileo Thermometer works on principles developed by Galileo Galilei (1564-1642), the pioneer of modern astronomy and physics. Through his experiments, Galileo discovered that liquids change density as the temperature increases or decreases. Galileo Thermometer How it Works A large glass tube is filled with clear liquid. Floating inside the tube are five small glass bulbs. The bulbs are calibrated by filling them with precise amounts of colored liquid so that they have a specific density relative to the clear liquid in the main tube (some bulbs are calibrated to be higher in density and some are lower). Finally, metal tags that serve as counter weights are hung from each bulb. A temperature is engraved on each tag. When temperature rises, the liquid inside the glass thermometer tube becomes less dense and the liquid-filled bulbs will sink. When the temperature drops, the liquid inside the tube becomes denser and the liquid-filled bulbs will float. Since the bulbs are different density, some will sink or float more than others. It's not just a decorative thermometer, it actually works! Each bulb inside the Galileo Thermometer represents a temperature, as indicated by the metal hang tags beneath each bulb. The temperature is determined by the lowest floating bulb in the thermometer. When a bulb is seen floating in the middle of the tube, the temperature reading is between that bulb and the lowest floating bulb at the top of the tube. If all the bulbs float to the top, the temperature is less than the lowest floating bulb. If all the bulbs sink, the temperature is above the highest bulb.
