Synopsis: A poster with the following content: Message: ""If your dad goes for open defecation, tell him - Chi, Chi and Thu, Thu!"" Henceforth, Open Defecation is Banned. Be Responsible! Human faeces are filled with disease-causing bacteria. Demand that your father builds a good toilet and keep it clean at all times. Rationale: Children are change agents too especially children who attend school. They are taught, and they learn to practice good hygiene and sanitation at school but when they don't have the same facilities at home, they are unable to practice them. They can influence their parents on changing this. Display Options: Primary and High Schools.
