Natalie loves to "hit" things. Give her something big and she'll open her palms and bang on it to see what sounds it makes.
Yesterday, we went to visit her great maternal grandmother who is over 90 years older than Natalie. While there, a big metal tin attracted Natalie's attention and she hit it a few times and then hit it some more because it made a loud, hollow, ringing sound. Later, when we opened it, we realized Natalie had turned all of her great-gramma's delicious eggrolls to crumbs!
