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.

They are soft-

I make videos like this once a month all year long while supplies last:

Sucks that I just ran across this. But I straight up love your channel! From one Engineer (Electrical here) to another, imagine doing this with a pressurized air cannon. Find a way to spin the disk, chuck it out in a straight trajectory and see just how far it

0:30 It's spinning isn't it? For some reason, I would not have thought about spinning the rock until I saw someone use a robot on some contraption. Happy to see it wasn't just spinning. There were multiple things contributing to this. Well done. I truly thought "As long as I can throw a rock to land on the flat side that spins allot, that would yield the best results." at the start of the video.
