My grandson age 7. He has some wonderful, if rather outlandish ideas about anything and everything. His way to stop you touching your face during the current coronavirus crisis. You buy a lot of penguin poo. You smear it all over your hands. (You won't want to touch your face with smelly hands). Everything you touch you will have to clean. When you want to eat and prepare food, you will have to wash your hands thoroughly to get the poo off and make them smell nice.
