Galileo Liquid Glass Thermometer Temperature Floating Visual 9.5" 24 cm RM2811

Galileo Liquid Thermometer Galileo Was an Italian Physicist, Mathematician, Engineer, Astronomer and Philosopher who founded Modern Physics and invented the Thermoscope. Based on law of physics, specific gravity of liquids change as they expand at different temperatures. Thermometer is a Sealed Tube made of Glass Contains 4 Floating Glass Spheres filled with colored liquid 4 Metal tags (calibrated counterweights) attached to Bubbles that tell the Temperature Stands Approximately 9.5" Tall (24cm) Measuring Temp ranges from 60.8°F-82.4°F (16°C-28°C) This Thermometer works on the principle of Buoyancy. The individual floats rise or fall in proportion to their respective density as the temperature changes. So How do I tell the Temperature? The bubble that sinks the most indicates the approximate current temperature. Great Conversation piece! Perfect to accessorize your Desk, Dorm, Classroom, Bedroom or Office. Makes a Great Gift Condition: New Keep out of direct sunlight Note: Buyer will receive (1) Galileo Thermometer, per quantity of (1) purchased.
