Pencil has a variety of faces. Have you known ? This movie is one of the pencil art. When I watched it first time , I was surprised "Are they pencils ? Oh no ,　it is unbelievable ".I will be happy if you are interested in pencil after you watch this .
Today's main topic is Pencil.
I have three subtopic this week.

①Relationship with paper
Paper is made with infinite fine wood pulp.When people write paper in pencil , pencil lead is rubbed into the paper. In other words , black lead witch is chipped off with clay enter into the fiber of paper. Once it enter into paper , it isn't able to erase  by slight rubbing. The word that is written in paper and isn't able to erase is not able to write on plastic. For example , when you use pencil on plastic , pencil lead and clay are leaved on plastic.There is no guard on plastic , so black lead don't leave as words.

②The reason for paling words which were written by pencil.

Have you experienced some words you wrote in notebooks many years ago become obscure ?WHY?WHY?WHY?There is a reason in the way pencil lead enters into fiber of paper.Main element of black lead which is material of pencil lead is C(carbon).Carbon is pigment , so , strictly speaking , pencil lead is not enter into fiber of paper , but attaches to paper and it doesn't soak into the most deeply point of the paper . Especially , dark pencil lead has possibility of paling. If you want to prevent words from weathering , you need to cover paper with clear paint .

③The way of using pencil
Do you have confidence in your using pencil style ? I don't have , and I have ever seen many style . So I introduce perfect style.
Point①
First , you put your forefinger on 25mm from point of pencil .Second , you put your thumb on the behind of forefinger and put middle finger on the front of forefinger .You hold pencil by these fingers softly .You bend your third finger and little finger along midle finger .

Point②
You　hold pencil along your forefinger.
Point③
If you hold pencil by the right way , the stem of pencil will incline 60°　to　the paper. You should incline pencil 20° to right.

If you master this holding style , you will be able to wright beautiful words. And , when you become parent , you must teach the way of holding pencil .So , this lecture will be useful.
