    You still need to show work for conceptual questions.

    What is your best attempt at explaining the lettuce spinner?

    I'm not even sure what a lettuce spinner is. Maybe that's the problem.

    I know you fill it up with water and you lift the bowl up and the water will exit through the wholes. The lid has a spinner on it which allows you to get rid of any extra water.

    This could work because of circular motion. The force is being exerted on the lettuce causing the water to escape. How wrong am I?

    The force is being exerted on the lettuce keeping it moving in a circle. The water drops do not have as much force pulling them in a circle so they fly off in a straight line.
