Galileo Thermometer and Storm Glass: History and Working

Ancient inventions were amazing! Ain’t they? Can you list out in your mind how many inventions you can memorise?

I bet you wouldn’t have remembered this invention until and unless you were supposed to research the Galileo Thermometer and Storm Glass Uk.

Back then there was a physician known as Galileo Galilei, who was mostly called as the father of modern physics, father of modern science and father of scientific method. He was the one who gave the principles of the Galileo Thermometer and till today many of you still think that he invented the Galileo Thermometer, which he didn’t.

It was just that he developed the principles and later in the 16th century the thermometer got the name of Galileo in its prefix. He found out how the different coloured bubbles with their unique temperature move in the sealed glass tube. He noticed it in relevance to the outside temperature.

The Galileo thermometer was invented to analyze the temperature outside the tube. It was one of those great experiments and inventions done by Galileo Galilei in the 16th century.

Let’s have a look at how does a galileo thermometer works:

Before looking at the working, let’s go through with how a galileo thermometer looks like!!

Galileo thermometer is a sealed glass tube with some water and different coloured bubbles in it. There are five bubbles in a Galileo thermometer and those are blue, yellow, green, purple and red bubbles. Each bubble carries a tag which states different temperatures with them.

The blue bubble contains the tag of 60 degrees, yellow bubble contains a tag of 65 degrees, green bubble contains a tag of 70 degrees, purple bubble contains a tag of 75 degrees and the red bubble contains a tag of 80 degrees. The bubble which carries the least temperature contains the highest density and the bubble which contains 80 degrees has the lowest density.

Now, coming on to the working of the galileo thermometer! The principles of the galileo thermometer state that,

If the outside temperature of the glass tube is 75 degrees then the bubble having the lower density than of 75 degrees will float upwards to the top while the others having a lower density than of 75 degrees will float to the bottom whereas the the 75 degree bubble will float just below to the bubble at the top which is having a lower density.

This is how the galileo thermometer works whose principles were given by Galileo Galilei.

Now, approaching to Storm Glass :

NEWS and NEWSPAPER were the medium which helped to convey the weather forecasting reports to the public then it’s our cell phone which gives us time to time report about the weather to be for that day.

Have you ever thought about who might have invented this technology back then in the 16th or 17th century?

Earlier it was Storm Glass which was the invention of Admiral Fitzroy. He was the physician of the 16th century. His aim behind this invention was to predict or forecast the weather of the outside world.

His invention made it possible to analyse what kind of weather it would be for a particular or in a particular environment.

What was the storm glass made of?

Storm glass was a sealed glass which consists of distilled water, ethanol and potassium as the ingredients in it. These ingredients become crystal and form different shapes according to the outside weather.

Let’s have a look at the different kinds of changes according to the climatic condition of the outside world!

  •       In the storm glass tube, if you see some threads on the top floating on it, then it would be windy outside.
  •       If those small crystals remain on the bottom of the sealed glass tube, then it will indicate frost.
  •       If you see small stars in winters, then it indicates that snow is coming.
  •       If the sealed glass tube turns out to be cloudy with tiny stars it indicates a thunderstorm.
  •       If there are small dots in the storm glass tube then you will see humid and foggy weather outside.
  •       If the liquid in the storm glass is cloudy then you will see the weather outside will also be cloudy.
  •       And last thing you would notice in the storm glass is that if the liquid inside the glass is clear then the weather outside will also be bright and clear.

Hereby, the galileo thermometer and storm glass were the invention of the 16th century which were invented to analyse the temperature and forecast the weather.

The galileo thermometer and the storm glass are also available online. You can buy one and experience those ancient experiments that these scientists did. Just go through the workings first and then have a look if there are changes in your galileo thermometer and storm glass.

Believe me, It would make you live back in the 16th century.
