Two of his favorite rooms in the museum were the water room and the grocery store. In the water room, John played with some boats in this huge display simulating how water evaporates into the air and then returns as rain. He also practiced writing his name on a blackboard with a paintbrush and water. The only bad part about this room was the fact that John kept trying to drink the water.
Here's a picture of John with his Aunt Katharine and Grandma Kay Ellen after we left the museum. It was time for his nap in the car!
