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.

“Ongoing struggle to be the favorite uncle.”
My question is how he isn’t yet.
@Home Of Rugby
No hes Morgz thats why the other uncles losing
He must be the very best uncle, he is like a personification of happiness.
Alina Liu their uncle might be bill nye
Wait... 666 likes?
It hurts my soul to not like this comment, because it has 666 likes.
I can almost hear mark saying this
"I used to suck at rock skipping
but im great at engineering.
Which automatically makes me great at rock skipping."
Ha dart board
wat XD
Soupt0 did you read the replies
Get rid of used to
Dude Mark Rober rock skip scince young and things like he can engineer can help you plus if you don't know how to rockskip than don't say without thinking
Spotting your son in this video, and now knowing that he is your son, makes me happy
ikr i also spotted him

Its crazy that one of those kids is his son and we never knew it, Man is goated 🐐🐐

This is how you can get kids to be so engaged and maybe
down the road to be future engineers :)
And you get some good quality family time, loved this so much
So this guys like... the REALLY cool uncle
Like, the really, REALLY cool uncle
the forsin21 yeah.
Well my parents are divorced soo
...
the forsin21 or Jake paul
1:30 the kid saying "I knew it" lmao they just know he's going to cheat at this point
That mysterious mound covered by a green tarp might have been a bit of a clue.
"Cheat" is a strong word. He's using a slight advantage he created. :)
@@TerryTWeiss he is 20 year older than those kids so he already has small advantage over kids. Anymore advantage is cheating
@@ayushkumar-bg1xf just cuz hes older doesnt mean hes better
ayush kumar i guess by that logic if a 20 year old non-experienced adult went up against an experienced 9 year old in a running competition the 20 year old would surely win
imagine being an adult and have all the children you know just automatically assume your going to use a robot to win

@@regenpalkar4385 you are too late
Can you imagine how advanced we would be if everyone had an uncle like this guy? I don't know if those kids are into engineering or not but without any doubt he inspires creativity even beyond his family.
My son yells at me from upstairs. "DAD, DAD! You won't believe this! Mark Rober is skipping rocks at Lake Cavanaugh!" My family has had a place on Lake Cavanaugh for over 50 years and not that far from where this video was shot. Our place is on South Shore Drive just across from the big island. We go there every July 3rd. My son has been a fan of yours since we were trying to gain an advantage at the Pinewood Derby three years ago. This video made my son's day. Keep up the good work.
That's funny, my dad used to own a place on South Shore Drive across from a big island until about 50 years ago when a man calling himself "Moderngraded" stole his land
We will definitely look for it next time we're there. My dad probably knows your family. He knows everybody. I'm sure your family is familiar with mine in one way. Every Fourth of July my cousin Brandon lights a cannon off every few hours or so. I swear it echoes all the way to Whitehorse Pass. Sorry about that. Anyway, my son is giddy over your comment. Thanks again.
Hahaha. Well Retrograded is where it's at now. We are obviously very popular with our two videos. But one of them is the best video on the Hoh Rainforest you will ever see. LOL.. My son's 4th grade research project.
I'm coming to ur house lol.

mark rober: build robot that skips rocks perfectly
michael reeves: the roomba that screams when it hits things
You have to admit, that Roomba is amazing.
Michael is Just Dr. Doofensmitz without the sad story
@@ifyouwoooshmeyouhavesmallp7603 Doofinschmirtz?
@@avenator3295 in my country he is called doofensmitz
The two paths mechanical engineering can take you
I think what's even better about Mark building the robot is the fact that he didn't came with it already perfect, he allowed the kids to be a part of the trial and error stage, to experience what it's like to try out a bunch of variables, and then experience the immense happiness when one of them finally works. That alone would probably make me inclined to start doing my own projects.
Had a teacher back in the mists of time that said "If you don't record your results you're just messing around." Great stuff Mark!
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....
Haha that’s great
One time my brother threw an egg at me. It hit me in the head and bounced off, then hit the ground, and never broke.
I wish I could meet him
hard boil it as long as they don’t say you can’t
*"They changed the rules of the competition after that....."*
(Love this part)
Be like kids go on school camp
Everyone else: 5-6 skips
Those kids: 50 skips
4:40 hate to be her
@@leonardopaulsen2116 lmao
Me: 0
Comrade Stalin i can only skip like 3 times 😂 it’s my record
i try to skip rock and the moment i throw the rock in all i heard is doank and i never see it again
2:58 Mark actually showed his son in this
yes,
He actually did in a lot of videos
He actually appears all throughout the video a whole bunch of times, like at least 5 times I think. Watch it again. He's also in a few of his other vids too
But we didn't know that he was his son
@@technoboyashank4607 yes but he showed him and didn't mention it is his son. As if he wouldn't let his son participate in all these things xD
Okay but if this man's contact isn't in any of these kids' phones as 'Cool Uncle Mark' than that is an actual war crime.
wait what about his children?

@Andrew Riela o
imagine your uncle pulling out a rock skipping robot and your immediate reaction is “I knew it”
Clever :)
Knew it
Do you believe that or not
Lmao
True 😂
WIRED: Its impossible to skip a rock 89 times
Mark Rober: Hold my beer
OMFG LMFAO HAHAHAHA
Nah hold my phone phone nevermind it can do that itself
Lol tru
Ha
No, it should be Mark: Hold my Curiosity Rover
I love how they named it “Skippa”
I didn't notice your son the first time 😃. Can totally see what you were talking about in your more recent video but he seems to be handling the noise like a champ. Honestly, I use to consider you one of the most compassionate RUclipsrs I subscribed too but you continue to impress. All the best man...
Goes on family vacation

Mark: so here is this fun engineering project I thought we could do
He would definitely be my favorite Uncle

The dislikes are from soil scientists because you called clay wet dirt.
Umm.... Clay is wet dirt like soil is dead humans
Dirt/loam is a mix of rock, sand, clay and silt. Silt is mostly dead bacteria that have decomposed organic matter (leaves, sticks, poo, dead animals) I think sand and clay are similar and silica based, but clay is worn into a flatter shape which is why it is found by rivers. The river washed out the silt from the loam and wore the sand down. Mark is sort of right, but not quite at all. Loam without rocks, clay, and sand is called humus, but most people would still call it dirt. Dirt/Loam without silt is clay. And depending on where you get the dirt, usually its clay content would be pretty low and wouldn't really work for making any sort of pottery.
geology isn't a science
Samy Meftoul did I say geology or a geologist?
They didn't use wet dirt. they used CLAY DAD!
That's right...and when they ran out of clay, they used wet dirt.
I love the way you include the younger members of your family and extended family. So many children grow up without having that experience. In my own up bringing the children we’re always include in the learn experience. My dad and uncles being builders and engineers. From my uncle Rody, an engineer who worked on aspects of the Apollo capsules thought me to never give up.
Mr. Rober as a family we are so grateful for fascinating and appropriate youtube content. Our children love it and learn from it and we adults love it too!
Adelante
I love how everyone in the family is used to mark having the crazy inventions 1:33
"I knew it" - random nephew/niece at 1:32

@@arianimations6255 prove it lil one.
Look at his channel, he actually is
Today We Built how about the one in yellow
I'm impressed he is teaching his nephews and nieces to engineer. And making it fun at the same time.
And there's the fact that he's doing the same thing for us on RUclips.
Uncle Dane is like that too
Risk_TheAgentBoy SPAHS sappin’ mah sentry
This makes me realise I should have choosen Engineering. I am a born Engineer and also smart enough to get into a good college.
I usually do this testing and then finding the optimal performance and stick to it and never think about it for the rest of my life.
But,
Just because everyone was taking up Engineering in my country like a no brainer, i wanted to do something different and took up Geology and now i hate that subject.
Harish Gupta never too late to start, go for it
As as professional engineer and professional rock skipper, that has to be one of my favorite videos on RUclips. Great job Mark!
Ok let's be honest here... I'm come back to this video... after watching marks son video. It's serious awesome 🔥
Anyone else? 👍

Im 30% sure that that was mark rober himself
*NO WAY!*
🤯 You have changed my life! I will now start my journey to becoming the rock skipping champ!
That flyby shot at 4.55 was awesome. Nice work.
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

Mark, You are so awesome with your family! Such a role model for kids!
I'm almost jealous of those kids of having an uncle like this at an age like that. Even just for going on trips like that.
Thank God I'm not the only one!

@@twynics3958 better, tell them they had better be as cool as mark to their future nieces and nephews and watch them freak out xD. Best thing is seeing kids scared as they realize the future is a thing, and then meet every expectation and beyond thanks to what you've done. Keep it up Mark =)
Great video!
Why is this not hearted?
It is
3rd

Dude you just brought back crazy memories when you mentioned lake cavanaugh, I remember going there with my brother and that lake in the video looked the same as I remember it
When I’m older I plan on being a engineer, just like you. Your videos are awesome! And give me hope❤ Best engineer ever!
The kids: I can skip 3 rocks
Mark Rober: I can skip 10
Me: how do you skip a rock
Me: what is a rock
10 at a time? if so he is like god level
3 rocks or 3 times?
You skip a rock
the rock need to be flat, and high quality
Next project: Clone Mark Rober so that he can become everyone's favorite science uncle
I wish he were my uncle and I am older than him!
LIKE LIKE LIKE LIKE LIKE
He's the definition of a cool uncle!
Just make him president, that should do :)
I WANT ONE
HOOK ME UP
I love you involve your nieces and nephews in your science projects, this will build up in there congruence as a muscle memory to have fun is to invent/discover our understanding of this world in general.
Love from Pakistan 🇵🇰♥️❤️
The nice thing about Marks videos are that when it comes to the science part its still fun to watch and learn
The more of these videos I watch, the more I wish you were my uncle x.x
Same here dude
I completely agree, cool uncles are the best
7:50 looks like you slapped him lol

yea

I somewhat envy the excitement and environment your family has. Truly seems quite nice.
I saw a study on that like 10 years ago, and their robot was essentially identical! I haven't finished the video but I'm psyched to see if they came to the same results
Instructions unclear.

“The only difference between screwing around and science is writing it down.”
Wow, gonna take these words, thx
I love that you're so committed to science. But you're probably the best uncle ever...
Great content for teaching kids the EDP. You are my son's hero.
instead of the title "Rock Skip Robot - The SCIENCE of PERFECT ROCK SKIPPING"
The title should be
"How to be the best and most liked uncle"
But wouldn't that be every single one of his videos?
Daniel Dorgan It would be a series.
1:00 dude wtf mark is ripped
What I said as well... It's not that it's illegal or even unsuspecting, generalizing, race or anything. I just honestly didn't expect it.
Kudos to him and I applaud the man for staying in tip top shape and having time to be the brilliant man he is.
This man has achieved more than thousands do combined in a lifetime so it bewildered me.

10:21 that ending was amazing
You have inspired me to design and build a robot that skips leg day
I don't think I'd graduate from that rock skipping boot camp. The curriculum sounds a little rocky.
More than rock skipping robot i loved the way he made his nieces nd nephews work as a team. Each of them according to their age nd intellectual capability was helping the project. I remember this saying from LOTR, if u want to go fast go alone nd if u want to go far go together. Guy didn't just create scientific instrument, he passed on legacy.
You are probably THE coolest uncle out there. Just saying.

I have not skipped rocks on water in a long time but the last time I did, I was able to get one to skip a long ways. I learned how to do this on a lake very similar to the lake featured here in this video back when I lived in NY.
I am doing an experiment on rock skipping for my IB physics class. Can I please have your robot? I dont know what else to do. I am out of options, Mark! If you have other ideas for physics IAs as an alternative, PLEASE LET ME KNOW! Please send any help!
