Ever get tired about getting the clothes wet during rainy day when u're not in home to "save" the clothes. Let's find a solution! You now have a little container beside the clothes. When there is rain, water goes in. It gets heavy. Using a lever system, the weight of the water container can convert to a motion to close a waterproof cloth up above the clothes to prevent them from getting wet (Apologize for my bad English, I'm only a student who's not living in the USA.)
