About this 3D model

I was working late one night on my project for school, and I asked my friend to name an object. He said duck. Then I asked him to name an object that doesn't come from an egg... All he could think about was objects that came from eggs. Then he said, "rocket," and I said, "okay." I then proceeded to make a rocket within a hollow egg. I liked the rocket idea, because I'm majoring in mechanical engineering, and I've wanted to become an aerospace engineer for several years.
