DIY Survival Water Filter (charcoal base)
Very easy project to do and doesn’t cost anything. remember a person will die in three day from the lack of water. so don’t forget to boil or treat your water because filtration isn’t enough by itself. P.S. Pack the crushed charcoal into the container TIGHTLY. The idea here is to create as fine a matrix as possible for the water to DRIP through slowly, thus trapping more sediment.
