1. Take a proper amount of mung bean and soak it for about 24 hours until the bean sprouts are drilled out of the mung bean skin and ready to germinate.
2. Drill a few holes under the Coca-Cola bottle, enlarge the size of the holes with small scissors, so that mung beans just don't come out (in order to keep the water poured into the bottle every day and ensure the freshness of mung bean sprouts), and cut off the conical part of the bottle mouth to facilitate ventilation and watering in the bottle.
3. Put the soaked mung beans in the bottle, which is about one fifth of the height of the bottle, to give the bean sprouts a space to grow.
Wrap the bottle with a layer of cloth or paper. As long as it is opaque, the transparent bean sprouts will turn red. This is very important, so pay attention.
5. When you start watering for the first time, water will naturally flow out from the bottom of the bottle.
6, spread a layer of cloth on the bread, it must also be opaque, remember.
7, try to water 3 times a day, morning, evening and office workers once a day.
The bean sprouts made by this method are thick and long because: because the bottle is very narrow and there are many beans, the water loss is not much and the bean sprouts grow more vigorously.
