MOCKANA
Medium Galileo Thermometer
Product description
The Mockana “Medium” Galileo thermometer is a 30 cm glass thermometer that uses colourful, floating spheres to indicate the ambient temperature. This Thermometer works on the principle that the density of a liquid changes as temperature varies.
Product features
- Function: The Mockana Medium Galileo Thermometer is a decorative, analog thermometer used to measure the ambient indoor temperature. It is designed to be a conversation piece that demonstrates a scientific principle.
- Design: It consists of a sealed glass cylinder filled with a clear, non-toxic, and ozone-friendly liquid. Floating within are several colorful glass spheres.
- Mechanism: The thermometer works based on the principle that the density of a liquid changes as its temperature changes.
- As the surrounding temperature rises, the liquid inside the glass cylinder becomes less dense, causing the heavier spheres to sink.
- As the temperature drops, the liquid becomes denser, and the lighter spheres will rise.
- Reading the temperature: Each floating sphere has a small metal tag with a temperature marked on it. You can read the current temperature by observing the movement of the spheres.
- Find the lowest sphere in the top group of floating spheres.
- The temperature on the tag of that sphere indicates the current temperature.
- Accuracy: Galileo thermometers are considered more decorative than precise and are best for approximations. Some sources reported an accuracy of about ±1 °C.
Product specifications
Dimensions
- Height: 30cm.
- Item length: 30cm.
- Weight: Approximately 0.39 kg.
Materials and components
- Outer tube: Sealed glass cylinder.
- Liquid: Clear, ozone-friendly, non-flammable, and non-toxic liquid. In many Galileo thermometers, this is an alcohol-based solution like ethanol, which changes density significantly with temperature.
- Internal spheres: Seven colored, glass spheres.
- Tags: Seven metal tags attached to each sphere, each inscribed with a different temperature.
Performance
- Temperature range: The thermometer measures a range of indoor temperatures. The exact range can vary slightly, but a typical 30cm model measures from 16°C to 28°C.
- Accuracy: These thermometers are primarily decorative and are considered approximate rather than precise. A weight differential of only 2/1000 grams in the spheres can achieve an accuracy of roughly 1°C.
- Display type: Analog.
Construction
- Handcrafted: The thermometer is almost entirely handmade.
- Free-standing: The design is intended to be displayed on a flat surface.
Reading the temperature
The temperature is read by observing the lowest of the spheres that are still floating in the upper part of the glass cylinder.
