    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.

Fun egg drop story since you mentioned it at the very end. My dad is a retired architect, and in college one of his engineering classes had an egg drop competition. Lightest structure to have an egg survive the drop wins, yadda yadda yadda. Well, my dad asked the professor where they were holding the competition and it turns out that it was from the roof of a single story building, throwing the eggs into a grassy lawn. He then asked the professor how many tries they got and he could try as many times as he wanted. So my dad bought two dozen eggs, went up to the roof, and started tossing. Eventually, one landed without breaking, which meant he won with a structure of zero weight. They changed the rules of the competition after that....

What could be really admired in this video is your patience with children since you have managed to draw your attention to the scientific method, engineering, data science, where they have had a great time launching rocks, taking notes and numbers, tables, angles, and have participated in the recording of the video with their own smartphones. I wish we could all learn like this, to teach the new generation in a healthy way, transferring the learning process to the games, instead of just criticizing the way we think they miss the technology that is within their reach. In addition, this is filmed in an absolutely incredible environment, and teaching them the importance of respect for the environment in technological development in the process. I have learned a lot from this video. Thank you for sharing your inspiring work with us and with the children

Put 2 fingers on the Rock and let it be parallel with your two fingers, spin it off your fingers throw the Rock at a 20° degree angle to the water, spin the rock as fast as you can and as hard as you can.

The fascinating thing is that marks videos are vlogs and teaching at the same time

My son (9) is dead set on perfecting his rock skipping skills after watching this video. He wants to make his own clay discs and rocks to practice. Can you tell me what kind of clay to buy for this? We want to make sure it is natural and dissolves like the one you used (maybe a link). Our whole family just loves all your videos! Thanks!

At the end if you have subtitles on you unlock two things that mark learn when he was in china. A nice Easter egg for the deaf viewers.

But first, a robot that skips YOU, …or a GoPro, to simulate skipping you.
