Mark Rober hat für seine Neffen und Nichten einen Steinflitschroboter gebaut, der – natürlich – perfekt Steine flitschen kann.
Summary: 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:
1) Rock angle of 20 degrees
2) Rock PATH angle of 20 degrees
3) Spin the rock as much as possible
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.
