Summary Comments : [Mark Rober] SCIENCE CLASS #4- How to Waterproof Your Hand

DJ****:

My idea for the next class: We use centrifugal force to our advantage. Let's say we attach some object- possibly a person- To a one meter long wooden plank or iron rod, or some other long, solid object. Then attach the other end of the rod to a motor which spins the rod and the person in a big 1 meter radius circle. If they spin at about 3.13 m/s, the centripetal acceleration they'll feel would be 3.13 squared, or 9.81 m/s^2- exactly the same acceleration that we feel by Earth's gravity. From there we just measure the centrifugal "force" on the person, and boom. We've just measured their weight in zero gravity.

Mi***********:

My friend: so what is your favorite song genre?

Me: it’s complicated... 11:43

Ge**************:

this is completely off-topic and late but i have to sudden urge to let it be known that the bowl at 2:00 is the same kind i have at home

Se*****:

Are we going to ignore that he used a hotwheels track to point 4:23

Ae***:

5:19 Video Start
Love these vids your doing, & we are able to include them into the “schools” lesson plans for actual credit
Know some schools may not allow this, but my nieces does, it’s so cool. She likes the fun crazy projects
Be Well

Ju**********:

2:19 is dope i had to figure out to do that by myself

Ai**********:

At 4:30 ish I did the ohhhhh thing because I never understood why water could hold things and bend and overflow without coming out. I never really learned that so thank you Mark

Wy*************:

Anyone notice the hot wheels track as the pointer 9:03

Top Comments : [Mark Rober] SCIENCE CLASS #4- How to Waterproof Your Hand

Jo*********:

Hey Mark, when I tell my kids that Science Class is on with Mark Rober, they RUN to the TV to turn on the show. They love what you're doing and they're learning a lot. I hope you're able to keep doing it for a while!

Ke********:

Can we all just take a moment to say thank you to mark for making us these awesome videos

Di*******:

Mark : Eli come help me
Also mark : Get out of here

Da*********:

Why would anyone dislike mark robers videos, he’s literally the most positive person on YouTube

Co*****:

Cave Johnson here, On the contrary to what i usually say, you're hired

Ow**********:

The moment when you're sad cause you find out there's no class on Wednesday, then realize he's making a killer video instead!!

Mr***:

Simple math: Mark + Rober = BEST TEACHER EVER

Ma************:

My Science teacher: School is closed, we’ll have to transfer to online textbook work instead.
Mark: now wait just a minute-


Also I love your videos and classes they are so much fun during quarantine!! :D

A*:

Imagine water molecules holding hands during cohesion and they say red rover red rover send soap over

Dm****:

"How do astronauts weigh themselves when they are weightless and floating in space?"

Easy, they use the "Watermeloninator" which launches a watermelon at their center of gravity (mid section) where an astronauts equal and opposite reaction can be measured (F=ma) to calculate their weight on earth.

Ja********:

Fridays lesson: Ok kids lets talk about how to soap proof your hands.

Om***:

Mark: soap destroys fat
Fat people (like me): looks at soap
*few days later*
News: soap bar killed in mysterious ways

Pa******:

Imagine the NASA scientist dreaming of one day being a school teacher.

Do*****:

418 dislikes were the molecules who lost the tug-o-war...

Jk

We*******:

If only he became a high school teacher before I would graduate XD

Be*******:

"Weighing" a person in space, I'm envisioning a slow-spinning cylinder a person can strap themselves inside of off to one side, and a force/strain gauge measures deflect, math happens, then you get a "weight" (probably actually a mass).

Ka*************:

going to the comment section is the equivalent of talking to your friends when the teacher is explaining something

To*********:

Mark: Stops working at NASA to be a Youtuber
Mark today: I WANT TO BE A SIENCE TEACHER!!!

Os*******:

My takeaway from this video

Water molecule: Hugs its friend
Soap molecule: "HEY, NO PDoA!!!"

hk**:

No class on Wednesday 'I'm sorry'
If it were any other class that would be unnecessary

Fl***********:

Mark i don't how to say it. YOU'RE THE BEST HUMAN BEING EVER EXISTED

Ko***:

When mark becomes a physics teacher, he should make sure that his board pointer is a hot wheels track.

ev******:

Mark, you are amazing. It's so much fun watching you have fun.
I like how you make something positive out of this crisis.
This is something we should all do, follow our dreams. And yours is simple; to teach.
That example, that statement, is powerfull. I aplaud that.

To everyone; do what you like (as long as it's safe).
follow your dreams, and try to work around the crisis like mark is doing.
Stay safe and healthy, keep it going, lots of love from the netherlands.

Ra***********:

Just a random guess


Maybe astronauts could attach themselves to a spring and find time period for the oscillation and

Use simple harmonic motion to find their mass

No*********:

Mark: demonstrates surface tension of water on a penny
Also Mark: “that makes CENTS”

So******:

Instructions unclear: now I'm unable to wash my hands
how will I defeat the coronavirus?

Pa*******:

Did anyone notice he is using a hot wheels track part as a stick ?!!!!

si********:

That moment you are actually sad there is no class on wednesday

El***************:

Mark: No, you guys can't hold hands.


Me: are you saying that water molecules have to go on quarantine too?

Se*********:

The only science class I will ever attend (hopefully). Mark is actually interesting, explains things in an easy to understand format, and his voice isn't boring or flat. Other science classes explain things it a format I will never understand, their voice is so boring and flat I want to fall asleep, and don't use examples and diagrams. My real-life science class does use models and an easy to understand format, but their voices make me wanna fall asleep and the concepts they want to teach me are impossible to get a grip on without being explained properly. This is one of two science/engineering channels I will willingly watch, keep making great vids and thanks for teaching me! :D

ju****:

I just want to say that the way you teach is in my opinion the best way to go about it. For me at least, I learn and memories subjects the best when I get a mental model, only then do I feel like I fully understand it, which is exactly what you do. So if this is how you want to teach at schools, your students are going to love you. You'll be THE mister Rober from school, not just that famous guy from the internet (at least, that's how it worked at my school, the best teachers get school-wide recognition). Good luck!

Ca**************:

I have watched every single videos you have posted and every time I watch you I get more knowledge, more inspired and more convinced. Convinced on the fact that if I had a teacher like you in high school I would have taken much more seriously my studies, convinced that without passion you cannot teach anything, because if you want to learn anything you must feel passionate about it. I really hope that you can fulfill your dream because the world needs passionate teachers.
Also what would you say about a good collaboration video with Because Science after all this covid havoc is over I would really love to see that
