Thanks. Sodium polyacrylate[diaper] check. That was really helpful.
I know soaking someone's skin into waterpad can cause side effects. Obviously.
I just want to make an invention which can replace Humidifier and even better than that.Because most people suffer from dry skin rash.
Air conditioning is absolutely useful, but i think i need more than that to protect my skin or girlfriends skin.
Lack of moisture, only one condition, triggers so many loss such as hair loss, winkles, rash, intestine disease and etc.
