We are two sisters on a mission to demystify science with humor and relevance! One of us (Pinky) is a former high school biology teacher, and the other (Petunia) is a self-taught cartoonist! All of these products feature our Amoeba Sisters art illustrated by Petunia. We make a percent margin that we use to help support our free educational biology YouTube channel The Amoeba Sisters
