In January, major colleges and universities have taken winter vacation one after another. Some colleges and universities have winter vacation in 2021 directly across the new year's day, Spring Festival and Lantern Festival. The total time is 70 days, and most of them are 30-40 days, which makes migrant workers envious.

When students leave school, what about the flowers and plants in the dormitory?

Recently,Sun, a junior girl in Anyang, Henan Province, built a set of watering equipment for the green plants in the dormitory. It seems very simple, that is, put the green plant on the towel, hang a mineral water bottle upside down, and the water in the bottle falls on the plant drop by drop under the action of gravity.

Sun said that the green plant was a lucky tree in Brazil. He wanted to go home because of the holiday. He was afraid that it would dry out, so he used a rope to lift a mineral water bottle full of water and watered it above the green plant.

Some netizens are very interested in this equipment

-Remember to send follow-up after school.

-This student is very thoughtful, not bad

-It's the same as water for a mouse

Some netizens also questioned:

-A drop of water is about 0.05 ml, and a liter of bottled water is about 2000 drops, with an average of 5 seconds, 1000 seconds, about 75 hours. Except evaporation, it can be dripped for three days at most

-In fact, it's better to fill a bucket with water, then wet it with wool, make two circles around Brazil, and put the other end in the bucket. In this way, the wool at the other end of the bucket can keep wet because there is water on one side, and the Brazilian wood on the other side can continue to supply water. If you optimize it, you can adjust the thickness of the wool and the height of the bucket. It's absolutely no problem to keep a bucket of water for half a year.
