Hello everyone, it’s good to have you here. So today I will be sharing with us how to recycle used/spoilt battery. I taught my pupils this and it was such an interesting session all-together.
So let’s begin;
First, you need to collect the battery together and with a stone, pound it until the black powdery content is exposed and extracted.
Go ahead and add water bit by bit until you form a paste. At this, point you must ensure that the paste is not too sticky or watery.
Apply the dark paste to the board, and then allow it to get dried before writing or drawing on it.
This is usually the Amazing result of the entire process.
This is the best method to get a good black-board or chalk-board as some people call especially in the villages or rural communities. So for me after allowing it to dry for some hours, I decided to draw some beautiful pictures on it to endear the pupils to learn and appreciate the beauty of education.
I hope you found this post useful...
