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.

Mark Rober Former NASA and Apple engineer. Current YouTuber and friend of science. Answers to some common questions: 1) I studied Mechanical Engineering in School. I did my undergrad at BYU and Masters at USC. 2) I worked for NASA JPL for 9 years, 7 of which were working on the Curiosity Rover (I made a video about it you should def totes watch cause it's probably my favorite of all my videos). Then I created Digital Dudz (made some videos about this too) and eventually sold it after 2 years. Then I worked for Apple in their Special Projects Group doing Product Design as a Mechanical Engineer for 5 years. As of 2019, I just make my monthly YouTube videos. 3) Link to free and therefore substandard build plans for my custom workbench can be found below. 4) I make a monthly toy we build together on a video, that gets delivered to your house that teaches you to think like an engineer.
