Machine

My name is Calvin. My friend Alex likes to build things. I like to write code for computer programs. Together, we are a great team. We won a technology contest at my school last week. We built a machine that people loved to play with. If you turn a doorknob, a lever rises and touches a light bulb. The light bulb turns on, and a song plays. If you turn the doorknob quickly, the light shines brighter and the music plays louder. I don't know how to build a machine, and Alex doesn't know how to write code, but together we made it! My parents were proud of me. Alex's parents were proud of him too.
