SCIENCE CLASS #4- How to Waterproof Your Hand
Lots of juicy demos relating to surface tension! NO CLASS THIS WEDS!! I'm filming one of my normal monthly videos that day. Back on Friday though!!
Go check out Dianna's awesome channel- paprom.info/block/v/b5XHkL50x7CA3qQ.html
CHALLENGE- float as many paper clips as you can and then come up with a creative way to ruin the surface tension and have them all sink. Tag me on any social media with your responses.
Question for next time- How do astronauts weigh themselves when they are floating and weightless.

Thanks for attending! Remember, no class on Weds because I'm filming a normal vid but we'll be back on Friday with a super juicy one!

Please differentiate between the types of engineering. I don't know what to choose
Most positive PApromr

Heyyy can't u come to my school 😭😭
Trees use adhesion to suck up the water rom the rain like the paper towel.
I think 10
The kids that get you as a teacher are going to be pretty lucky.

Isnt your hand already kinda waterproof
You're gonna be an Amazing Teacher, coz you already are!
You would be an amazing teacher when you do decide to teach
i did this experiment in 6th grade, I think i got like 102
man i miss these
i just realized that mark wears the same hat in every video
Anyone notice at 3:49 that he used a hot wheels track to point at the mug lol
40?
Question: i broke several bones in my hand and had reconstructive surgery, there was massive swelling. When i started PT i noticed that the skin on my hand was ultra water proof like teflon. Its been this way for months now. Do you know why??

You sure that a virus has DNA?
My uncle used to put soap in the water tank where the cows drank to keep the ducks out of the tank. It broke the surface tension. The ducks would sink so they stayed out. I guess it was better for the cows to drink a little soap than duck crap. We also put soap on the hill in our front lawn. We had a lot of clay in the soil. The water would run off. The soap broke the surface tension and allowed the water to soak in.

Hi
Anyone heard of the flu
Lol his pointer is a car track
He always says "oi!"
nobody: me: SOAP POWERED BOAT
I need talc hairspray for rainy days please.
No
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!
I like your videos but this time it is too chaotic. You clearly didn’t have idea how to explain all of this information and you tried to improvise it a bit. It failed but don’t stop. I believe you will make progress as a “teacher” and your future videos will be much smoother
The paper clips didn't sink a bit bc of Archimedes and displacement.
What's with all the interlacing?
what is with arogel
oooo i miss a class wait teacher rober
Dude I love u but you could just your hand in Vaseline and wambam thank you Mamma you got a water proof hand
I think astronauts way themselves down near earth where gravity is normal and way themselves but not all the way
Me: gets a real boat and 10 buckets of soap 🚣♀️🚣♀️🚣♀️🚣♀️🚣♀️🚣♀️🚣♀️🚣♀️

I think that maybe you can put ummmm (thinks of first number in mind) 15 drops of water on a penny also I love your vids
What was the stuff the guy in the pool was covered in that stopped him from getting wet
Soap breaks down fat.. Yet fat is used to make soap.. Talk about washing the hand that feeds you.
Can't I just watch Mark Rober instead of doing zoom
Can't you just cut up a banana and rub it on your shoe and it will make it water proof
I’m a kid so hopefully I get u as my teacher in high school
i'm pretty certain that tall trees draw water up by mainly transpiration pull, not adhesion/ capillary action
I need this because of my hyperhidrosis 😂

This is fun. It's like see my science teacher in junior high school but without the cool presentation.
I hate school and I think this stuff is cool
Now this is a mug of water Also him he is using a hot wheels track to point to it I love your videos ❤️
What no way Really coollllllllllllll
Did enyone notice hes using a hot wheels track😂
35
38 drops
Hi Mark you should do this again!
3
Mark so does this mean that if I jump off a bridge into a river I’d have a better chance of surviving if I’m soaked in soap?
uhhhhh........
I skipped actual science class for this
1:40 Lol
Who else scrolls through the comments when the video is playing?
yAY maRk rober is my TecHer
if teachers showed this in class then school would actually be fun
Mark: This atom here... shows h2o Kids: THAT’S MICKEY MOUSE!!
I’m getting my tatoos redone and need this because I have them on my hand and work as a dishwasher and need to make sure they stay dry as possible
My dear i love your videos . Please give just 5 subscribers. GOD BLESS U.
Somehow i now no why theres no air in water now
im surprized u dont get hate! btw ily and im happy you dont get hate
my guess before i started the video was ground up aerogel (sorry i cant spell) but after watching through the soap part and stuff my guess is some form of powdered soap like a detergent or something
You make me like Science 😂
dam i raellly tried this im suprised thanks
If mark becomes a high school teacher and I have high school kids when he’s a teacher I am moving to whatever town he’s working in
Anyone notice that he's using a hot wheels track for a pointer lol go mark
mark: I want to work for NASA also mark: quits to do youtube still, mark: wants to be a high school physics teacher who else than mark: makes videos to train for it
I guess 18
Who else what him to be there science teacher at school!! I would listen and learn 10x more.
Who else wants to be in his class someday. Also so we just put baby power on our hands and it's waterproof?
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
I would love for you to be my teacher
fact: everyone would go to school if mark rober was their teacher
he will be a great teacher
It’s nice rober can afford drugs ...
Grow up Mark .. is this guy a rock spider ?

and team trees!!!

Fun video! You say at the end that water is magnetic. Is that really true? I know it's polarized due to its 4-point pyramid shape with 2 hydrogen atoms and two electron orbitals around the oxygen atom, so the side with the two hydrogen atoms is more electrically positive. I'm guessing that running water acts magnetically due to the moving charges but that still water is not magnetic. To test this, I think I can use a plastic sheet with a magnet behind it to watch the behavior of water droplets at various speeds, and I'm hypothesizing that still water won't be attracted to the magnet!
Soap is like controlling parents.
I have done 24 drops on a penny with a dropper is science before at school
not DNA RNA
You can use cinnamon too
can you please make an electronic configuration vid
This is the science class I'd attend
i got about 30 something but with dish shoap
Easy, just put oil
Pro tip: wear a glove.
Who else wants to become an astronaut now just so they can wring out a towel?
Mark, you should try making a giant raft that's completely powered by soap.
ho o r you
*This dude is better at explaining than all my teachers, combined*
Instructions unclear, my hands are on fire
I think astronouts creates ag acceleration as then weight
Mark: SOAP!!!! *yeets the paper*
