New dry toilet did not have wash basin :(. After using it we needed a place to wash our hands. We put the constraint to use “junk” material.
“The wash basin can only be made by new material (buy from the market), how can we make wash basin from junk, it will be dirty,” first thought/expression by the child who signed up for this project. “Then, I went around with my guide and we got many ideas, I tried one. One more joined and we tried it together. Then it did not work, we worked again. In between I left working on it, I worked again and I need to work more”.
