You two crack me up. I was really excited that Dad was going to show you some fun experiments using your chemistry set. Dad was a chemical engineering student after all. I figured he would have all kinds of fun things he could show you. You were really excited when you came running into the house from the garage where you were wroking. You showed me your genius as well as your dad's! "Ta Da! This is the molecular structure of a burp!" Talk about making chemistry relate to a 7-year-old! Great minds think alike! Like father, like son.
