Breakfast Conversation

I make a hot breakfast for my kids most school days. This morning was homemade biscuits and sausage. FE asked for butter on his biscuits and then proceeded to explain to me, in excruciating detail, why butter melts on a hot biscuit. The words coming out of his mouth included "particles colliding", "thermodynamic", etc. He's 9 years old, in third grade and knows more about physics than I learned in my entire life. This followed his conversation with me last week about Roman architecture and why arches help support buildings. I am so out of my league with this kid.
