Puff Away!


Victorian Britain was a time for many social changes (as seen by the efforts of various social reformers such as Charles Dickens) as well as great inventions.  One of the many amazing feats of Victorian engineering was the steam engine, which led to the rapid development of the steam train, which in turn enabled much movement of labour from the countryside to towns as the pace of the Industrial Revolution quickened and changed the nature of work for many people.

There are many preserved steam trains around the country, mostly run by enthusiasts.  We went to the Colne Valley Railway to experience what the railway system was like in the Victorian times.


There were various displays on site that related to railway life in the Victorian times but we were most fascinated by a restored steam engine that was used to pull plows in the fields.


It helped that the men who restored it to good working condition were there to explain the mechanics of how the steam engine worked.


As we went on the platform, we saw the steam train waiting to depart the station, so we went up to the driver's carriage and had a chat with the driver and the coal man who kindly showed us how to shove coal into the boiler.


We watched the train depart and come back to the station,


before we boarded the train to look at it, whereupon the burly ticket inspector came on board as well and asked to see our tickets, which we didn't have!  Luckily, Tiger managed to charm his way out of trouble by asking clever questions of the inspector about his job and the workings of the train, which evidently distracted the man so much that he forgot all about the tickets and proceeded to show Tiger a periscope-like instrument on the train that enabled the inspector to look at several carriages at one time, which sounded like a predecessor of the CCTV cameras!


We met a kindly gentlemen in another carriage who taught us all about the development of the Penny Black, as well as showing us his interesting stamp collection and taught us how to value them.


Further along, we came upon the mail carriage, which acted as a mobile post office where mails were weighed and sorted by counties.  Of course, back in the Victorian times the post office would have had its own train (we saw an abandoned Royal Mail train on site) rather than sharing its carriages with normal train travellers.


Stepping off the train, we went into the control rooms on the platform.  The rooms have been changed into a mini museum now where artefacts from the station's previous active use are showcased.  The exhibits also trace the rise and decline of the station use over the previous 100 years.


Before we left, Tiger had a go at working the signals by hand. 


Most young boys, at some point in their lives, must have dreamt of being a train driver.  When that doesn't happen, being the signal man probably comes in at a close second in terms of enjoyment.

When There's A Lot of Rain

It has been a very wet two weeks, so looks likely to continue for another week or so.


We have been down with terrible coughs so it has been slow going for the most part, and Tiger's neurological condition has taken a sudden downturn so between figuring out what went wrong to trigger the relapse and getting over our colds, we have managed to get a few things done:

1) Tiger had his birthday party at his grandmother's.


Despite the small-scale nature of the event, it was significant to Tiger in the sense that all the important people he wanted to have at his party (i.e. our extended family in England) were present, and that he is now officially in the double-digit category.  He probably feels rather 'grown-up', being in the double-digit age group, but he has yet to understand that there is a big difference between getting older in years and becoming more mature by way of responsible actions.  He is at the beginning of that journey.


2) A Lego workshop.


Unlike most children we know, Tiger hasn't been overly keen on Lego.  He has been given many different sets of Lego over the years so he is not short of materials to work with, but to my surprise, he hasn't spent hours immersed in it, unlike others boys we know.  Tiger uses his Lego pieces to build his own designs of various structures and aircrafts, but he doesn't like to follow any of the instruction manuals that came with each kit.  I can't decide whether this behaviour is part of his general don't-tell-me-what-to-do approach to life or that it is a show of genuine creativity because some of his own Lego designs are rather good.

As a result of Tiger's tendency to do things his own way, I have not taken him to any of the numerous Lego clubs until this particular structured workshop came up on our radar.  My purpose of taking Tiger to this structured workshop is to give him some exposure to new design and structural ideas that he can take away it to add to his own models at home.

At the 90-minutes workshop, the children were each given a set of pre-arranged Lego pieces and two instruction sheets.  They were to first build a mechanical swing set followed by a mechanised carousel.

 
The most interesting observation for me wasn't that Tiger could actually follow Lego written instructions to completion without help -- I resolved to stand on the side and only helped when asked, but it turned out that Tiger didn't need any help -- but what he did with his time.

90 minutes is about the right length of time for the children to build both structures at a comfortable, unhurried pace.  All the other children at the workshop dutifully constructed the set of swings, then moved on to the carousel.  Tiger took twenty minutes to build his swings set but instead of moving on to the next task like the other children, he spent the next 45 minutes 'playing' with his swings by altering its design, moving various pieces to different places.  While he was engrossed in his play, I was getting slightly anxious, wondering why my son was not keeping pace with everyone else.  After watching him for a while, I went up to him to remind him that there's another model to be built before the workshop was over.  Tiger just said,"I know!  I know what I'm doing."  What can you say to that?  So I retreated back to my corner of the room and prayed silently to myself that I hadn't made the mistake of driving 30 miles (each way) and paying for the workshop for Tiger to make one model....

Tiger did manage to complete the second structure, the mechanised carousel, in the last 15 minutes of the workshop:



3) Shakespeare in the rain

It bucketed down in the morning of the play.  We were having second thoughts about attending it, unsure of whether the play would be cancelled if the rain persisted.  In the end, we decided to brave the weather, mostly because I didn't want the tickets to go to waste, and I thought we would be alright since we had sheltered seats.


The rain didn't let up.  We were drenched from the waist down from the rain that came sideways as we walked over the Millennium Bridge.  Luckily the weather became better so the people in 'the pit' didn't get wet as the play went on.  I brought extra pairs of socks (but not extra pairs of trousers) so Tiger and I sat rather uncomfortably through the play, but we were glad we made it there because Tiger was soon greatly entertained by the production and had more than a few hearty laughs that afternoon.

A History of Paper Making and Printing


Inspired by Claire's very fine study of Gutenberg and His Printing Press, we followed suit to find out more for ourselves about this remarkable invention that improved literacy in the Western world.

We started by reading Gutenberg's story from the following books:


Some books only have a paragraph or so about the inventor and his invention.  We found the following to be particularly informative:


The two videos recommended in Claire's post are also very useful.  The first gives a short overview of Gutenberg and his printing press:


We particularly enjoyed watching Stephen Fry's investigation into the history of Gutenberg's motivation to invent the printing press:


Being part of a huge homeschooling community has its advantages.  There's always someone else who's interested in a similar topic at the same time as we are.  When an opportunity to participate in a 'history of printing and paper making' workshop at the world's oldest mechanised paper mill came up, we were only too happy to go along!


We were greeted with a short yet detailed presentation of the history of paper making and printing in Britain, and of the mill.


We then went on a guided tour of the mill.  The first machine we saw was the a paper making machine that is still actively in use to make paper.


This machine uses all kinds of recycled paper and even elephant poo as source materials!  The machine was using elephant poo on the day of our visit, but it was certainly busily working away.


We also saw the Fourdrinier paper making machine, which was installed at the mill in 1902.  It's a huge machine.  We were told that when any of the drums needed cleaning, a worker would have to "dive" into the hole (see photo below) to get inside each drum.  Either people were much smaller back then, or they must've used children (child labour was very common in Victorian Britain) because the hole is very small.


The Fourdrinier machine wasn't working when we visited but it is still in working condition, as shown below:


The foundations of the paper mill date back to the Anglo-Saxon period, and a previous mill in the same location has been recorded in the Doomsday Book.  We were able to see the Anglo-Saxon remains of the mill, which is the water wheel part that used to provide power to the mill before steam power was discovered.


Another part of the mill is dedicated to paper recycling, which feeds the pulp as source material for paper making.


The pulper wasn't working when we visited but, like the Fourdrinier machine, the Watford Pulper is still being used on other days.


We were also given detailed explanation of original printing presses that were installed at the beginning of the 1900s,


as well as the development of different type cases.


After the guided tour, we were given a detailed demonstration and talk on more about history of printing, engraving, paper making by a man who had worked in the mill since 1966, so he knew everything about every machine that was used in the mill and every step that took place in the printing process there.  We learnt much from his intimate knowledge of the mill and its processes.


Another part of the workshop has to do with paper making.  Tiger has made his own paper before, but that hasn't stopped him from enjoying the process again, after a demonstration by the workshop leader.


Tiger and I knew that the Chinese had invented paper making and printing a thousdand years before these methods reached Europe, so it was interesting for us to see this fact acknowledged in the exhibition gallery.


It was fascinating to read that T'sai Lun, who invented papermaking in 105 A.D., was inspired by how wasps make their nests, so we looked up the history of how papermaking was invented in ancient China:


Along with papermaking, printing technique was also invented ancient China, the basic method being individually engraved characters lined up to be printed on papers.  The same principle is used by the Western letter printing method.

Warwolf

During our visit to the Tower of London, we saw a reenactor dressed up as a medieval priest who gave us an overview of the history of the Tower as a royal palace, a prison, and a fortress.  A full-sized replica trebuchet was on site to demonstrate the power of this medieval siedge weapon.  It took five adults to launch the trebuchet.


The trebuchet is of special interest because the weapon has been traced back to being first used by Edward I during his siege of Stirling Castle.

While Tiger and I discussed about medieval siege weapons, I was given a quick education by Tiger of the differences between a trebuchet and a mangonel.  If your knowledge of medieval weaponry is like mine, i.e. that you think all catapulting machines work in the same way, you will benefit (as I have) from watching the two clips below:

1) Trebuchet


2) Mangonel


We learn much about the trebuchet from the following clip:


Why do we want to know so much about the trebuchet?  The main reason is that Tiger is passionate about everything that has to do with warfares and weaponry, historical and otherwise.  After hours of listening and watching experts talk about this medieval war machine, we decided it was time to build one ourselves.


It took us a few days to put the trebuchet together...


and when it was fully assembled, all of us thought it looked beautiful!


Naturally, we had to test whether it to see how good it is.


Unfortunately, our first few attempts at launching the trebuchet didn't go too smoothly.


The projectile either didn't go in an arc path, or was trapped in the launch net, or was launched backwards (gasp!).  It was slightly frustrating to have to work out what went wrong.  Not wanting to give up now, after we had spent so much time putting the model together, we pressed on with more tweaking, taking into consideration the following factors that might affect the success of our launch:
  • tension of string
  • length of string
  • weight of projectile
  • size of projectile
  • weight of counter-weight load
It's very exciting when it finally worked!

 

Tiger spent the rest of the day trying to break the record for the longest distance the projectile would go.  So far, his record is at 17 feet.


When we heard that Warwick Castle has the world's largest working trebuchet, we had to go and see it at work!


Check out the size of these real, medieval trebuchet balls made of solid stone!
