If you' re reading this then you' ve probably been using biros for a long time, and you' ve probably also tried numerous experiments with them. I' m sure that while performance those small experiments, you must have made some fun discoveries, so what have you discovered? I would like to hear them in the comment section below.

Biros are important because they help us keep records of things in a book. They are important to students, teachers, scientists, salesmen and women, and many other people. In fact, I can argue that without this small device, our society would not be this developed today, because as simple as writing and recording may seem, it has made humanity more intelligent over thousands of years because it helps pass information down to the younger generation, enabling them to have the knowledge of their predecessors and combine it with the new knowledge they have.

Our biros may have some problems that make them not to write probably or totally sometimes, below are some ways you can fix it;

Blow into an open ink cartridge: If your ink doesn' t have a cap on the end, blow into it or give up to the nib.

Draw on a piece of paper: When you start to see ink coming out, scribble a pattern of swirls till the pen writes fluently to make the ink is working as it should.

You probably know that pens/biros do not write when they' re upside- down, if you do not know this, then you can try writing with your book up and your pen down and see if it works.

So why doesn' t a pen/biro write upside- down?

Well, this is because they are affected by gravity. Gravity helps pull the ink to the tip on pens and biros, this enables it to write probably. But when pens or biros are placed upside- down, gravity also pulls the ink away from the tip of these devices, making them not work.

Thanks for reading.
