Galino

Galino Galileo Thermometer.
5 glass bulbs with temperature ranges from +18 to +26 degrees Celsius.
The thermometer is based on Galileo Galilei's concept that different temperatures affect the density of liquids.
The glass bulbs are calibrated to a difference of hundredth of a gram in Weight.
This means the lowest of the floating glass bulbs displays the current temperature.
When the temperature rises, the density of the liquid in the thermometer decreases.
The comparatively heavier glass bulbs lose buoyancy and sink.
When the room temperature decreases, the lighter glass bulbs gain buoyancy and gradually go up.
