It is all about contamination!
Inspired from the way bad water contaminate and ruin the nice quality of good water. It reflects something about global warming. If we do not use or consume the water wisely. The good water will surely disappear and reduces gradually. Do not wait till the world run out of water.
Here good and bad water collecting from different places..
You can see the contamination that is going on the various kinds of paper. The little dirt in the bad water devalue the good water. Clearly it made each papers very dirty and super grubby. The good water was ruined completely.
I tried on the newspaper, A4 paper, brown paper and the water color paper.
When they all dried, they became kinda crunchy. The dirt from the bad water did not appear as obvious as when they were wet.
The best paper that shows the most obvious stain is the water color paper!
