Description
Since my area is drought, fresh water is really necessary for local people. Sand is normally major material used to trap solid suspended in the water. I used sand and made a hole at the bottom of the jar and stuck lotus tree in that hole to allow water goes out. There are many different ways to use sand as filter material, so it's up to your skills and innovation(primitive way). Btw, I spent less time to get water than the previous video which was also showing about filtering water by using bamboo and it took me longer but this time it's much faster. Thank you for watching!
