Skipping stones takes a little practice and finesse, so Mark Rober enlisted his extended family to help build the perfect rock-skipping robot. Their creation, named Skippa, ended up helping humans learn, too.
I built a rock skipping robot with the help of my nieces and nephews to understand the perfect way to skip a rock. In the end we learned that 4 things matter most:

4) Choose a rock that is flat on the bottom and as heavy as possible for you to still get to your max arm speed.
