Emo-plant
In modern society, pressure in life and work makes so many people lose temper unconsciously and camouflage emotions repressively. American Polygraph scientist Cleve Backster found that plants, like people, have feelings and are more sensitive and accurate, while plants can reflect the changes of person's mood. “Emo-plant” is an oxygen tank, which helps us monitor our emotions. When people feel depressed, the exhaling poisonous gas will be directly transferred to the plant, and then the plant will reduce oxygen to prompt the changes of mood, to prevent the contagion of negative emotion.
