Rock Skip Robot- The Science of Perfect Rock Skipping
I built a rock-skipping robot with my nieces and nephews to find the perfect skip. We learned 4 things matter most: a 20° rock angle, a 20° path angle, maximum spin, and a flat-bottomed rock that is as heavy as possible without slowing your arm speed.
