Place an object inside of a black plastic garbage bag. First allow the children to feel the object from outside of the bag. If they are unable to guess what's inside, allow them to reach into the bag and feel the object. If they still don't know the answer, provide fun clues. For example, if the object is a framed photo of Mom, give hints such as "who puts bandages on your scraped knees?" or "Daddy thinks she's picture perfect."
