"Can this really produce fresh water?" The women were skeptical about Su Chen's idea.
No, it should be said they were very skeptical.
Because this method had already been tried by others.
It didn't really work.
The filtered water was still salty.
"Ahem, well, I'm not too sure myself, I'm just trying it out," Su Chen said, scratching his head.
Su Chen instructed the women to find some clean leaves.
He himself took some charcoal out of the fire pit.
This was the most crucial element for success.
Su Chen ground the charcoal into fine powder, and when the women returned with clean leaves, he laid them out flat, added a layer of fine sand, another layer of leaves, followed by the charcoal powder, and then more leaves, another layer of sand, leaves, charcoal, and leaves again.
In each section, there were two layers of charcoal and leaves.
Then he stacked them up.
Afterward, he took the makeshift filtration device to the seashore.
