Suspended Beauty

Sky, Mantis & Temp Gauge 022

 

This is a closeup of a Galilean Thermometer first developed in Florence, Italy by a group of scientists around the year 1600. Galileo discovered the principle on which this thermometer is based.

The sealed flask is clear, but I placed the device in front of green grass for visual effect.

The bulbs are hand blown glass with various liquids inside, and a weighted plate suspended from each bulb with a temperature embossed on its face. There are five bulbs in the flask and can measure room temperature from 64 degrees to 80 degrees Fahrenheit.

This device is based upon the density of liquid which changes in proportion to the surrounding temperature.Buoyancy determines whether an object floats or sinks. The density of the liquid inside the bulbs becomes heavier or lighter as the surrounding air temperature changes. Gravity also plays a role in the rising and falling of bulbs. Basically, as the temperature of the liquid increases so does the object’s density. Typically, the lowest floating bulb provides the approximate temperature of the area it is placed in.

I enjoy starring at the bulbs as they reflect light and colors in a myriad of shapes. I find this dynamic to be rather pleasant. I hope the Light within me is revealed similarly.

  1. Brother, love the last sentence about the light being revealed within you. I see it, others see it too.

    • Hi sis. I’m humbled, and pleased you, and perhaps others, notice my light which is certainly better than something else being noticed…haha!
