So we're driving through Vegas to California, and gratton wanted a drink at the gas station. I watered down some sprite and gave it to him. In the car, I glanced into the back seat and saw him doing something very interesting. He took the straw out and was putting his snacks (crispex and berry cereal) through the straw hole.. He was very proud of himself. I was mostly worried about him dumping it everywhere. I didn't want to stunt his creativity though, so I let him keep doing it. To my surprise, he didn't spill any, but instead let me know when he was finished, so I could take it away for him.
