Week 13: Motorized Spin Art

Written By Jeran Bruce

When something spins, like a washing machine, it creates this force that pushes things away from the center. This is what we call centrifugal force. It's like when you spin around with your arms outstretched, you feel like you're being pulled outward. A centrifuge is a machine that takes blood samples and spins them separating red blood cells, platelets and plasma. This is an essential part of diagnosing deceases like malaria. This weeks project will be using the concepts of centrifugal force to make an awesome spin painter.
