How do you drip water from a plastic bottle a drop at a time ?
October 5, 2008 8:22am CST
I'm using plastic bottles filled with water to drip slowly. The problem is the water does not flow at all with one hole punctured. With another hole punctured at the top of container the water just seeped off too fast. Anyone has a suggestion on how to make the water drip slowly like a drop at a time albeit the water is minimal for the plants ?

Drill the one hole, but drill it slightly larger than you did the first time. If the hole is too small, the surface tension of the water will keep the air out. By making the hole a little bigger, the surface tension across the hole will not be as strong and the occaional bubble will force its way in, forcing a drop of water out. You may have to experiment a bit to get the drip rate exactly right. Good Luck.
