the best way to make rainwater harvester is to do it by using a bottle, two filter papers, a thin plastic pipe, umbrella.
method:1. take an umbrella make a hole in it attach a rubber circle type holder.
attach a filter paper in that holder connect it with a plastic pipe fix another filter paper in the pipe.
and make a hole in the bottle and insert the plastic pipe in the bottle
