Henry: Hi Dad. I just made a model rocket out of three pencil crayons. The big brown one is the fuel rocket. The two green ones are the boosters. And... the white one is the space shuttle.
Erin: (muffled in the background) Tell him how it's held together.
Henry: I held it together with an elastic. And, they're actually the right size for the rockets. The brown one is the biggest. The two green ones are a little smaller. And the white one, the space shuttle, is the smallest. So, I love you. Bye.
