A group of students designed the string drip system to water plants without irrigation, as shown in the image. They placed a jug next to a plant with the jug's mouth above the plant's pot. Then, they placed one end of a piece of cotton string at the bottom of
the jug and inserted the other end into the soil, about 8 cm deep, close to the plant's root. They kept the string out of direct
sunlight. Finally, they added water to the jug. After a few days, the students decided that their drip was too slow.
