Machine writting 2

Imagine two pieces of metal the same size and the same shape.
On both ends of the two pieces of metal is a plastic handle with a circle in the middle.
The circles are big enough for you thumb and fingers to fit in.
In the middle the blades are connected by a nut that allows the blades to open and shout.
The blades are connected together and are as sharp as a knife.

The paper can now be sliced.

Machine writting 1

The old metallic dusty machine was left as still as a stone.
Waiting at the side of the desk, just waiting for that smooth piece of pearl white paper, to slide into the gap.
Just waiting to punch holes with its metal shiny cylinders.
With one the push of the metallic thin metal lever with EAST-LIGHT engraved onto it, the thinner pieces of metal  is pushed down to cause the cylinders to be pushed onto the piece of paper making a perfectly circular hole.

Fidget spinners should spin their way out of class rooms and quick

Fidget spinners should spin their way out of class rooms and quick


Fidget spinners have stopped learning and concentration they need to go.They have came in and now they need to spin their way out.
Some children can not focus or finsh their work cuse these pathetic spinners have taken over their body and mind, they need to go before they ask to be president.But why fidget spinners, no other toys are allowed at school.Teachers are always wanting kids to be focused but fidget spinners do the opposite they distract the kid who is spinning the plastic contraption and also distract all the children around them.There is no need to have these pathetic plastic contraptions, it is like an invasion it’s happened now these contraption should go.Fidget spinners are dangerous, if the blade is going at full speed it has the power to knock out a tooth get stuck in your hair and there are lots more hazards these fidget spinners can cause.
These spinners are dangerous, distracting and the noise is deadly so now fidget spinners should feel the undertow.  

If I were a class room


If I were a class room I would be that one, full will children learning and enjoying the space, I would have walls covered in art, covered in thought and detail, covered in writing, reading, and lots more.

If I were a shark

If I were a shark I don’t know if I would enjoy it, but maybe  I could be that one over there to the left, the one with thousands of teeth lurking in the shadows waiting for the seals, waiting to attack, waiting to eat and waiting to have a full belly, I would enjoy it then.
