SCIENCE CLASS #4- How to Waterproof Your Hand

Birt 30 mar 2020
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- ischats.info/fun/aMSaiYt1kqqGqao/v-deo
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.

Ummæli

  • 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!

  • 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 🚣‍♀️🚣‍♀️🚣‍♀️🚣‍♀️🚣‍♀️🚣‍♀️🚣‍♀️🚣‍♀️

  • 5

  • 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 😂

  • 30

  • 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

  • I imagine him throwing something in actual class on student.

  • 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 ?

  • 15

  • and team trees!!!

  • corno downis

  • 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*

  • Bro I love how he uses the hot wheel ramp as a pointer😅😂😅😂😅😂😂😂😂😂

  • Mark roger reminds me so much of one of my favorite teachers.

  • this makes me want to learn more

  • 16 drops

  • Cool!!

  • Flowt

  • As a physics teacher, I love these videos and would love to use them in my classes, but the auto-captions that they currently have do not meet ADA standards for my Deaf and Hard of Hearing students. ISchats makes it pretty easy to go through and edit the captions for grammar and accuracy (ie adding punctuation and correcting any words that did not transcribe properly). I know some of your videos have full and proper captions, would love to see that for this video as well!

  • obama

  • Mark it’s a beautiful Monday me nope Monday’s suck beside besides you videos

  • I’m a 23 year old environmental science major that’s watching this despite the fact I’ve learned this 100 times. Yet this is still entertaining Mark is the bill nye of the next generation

  • Hi

  • gg

  • funny

  • a fancy bungie cord

  • Mr.mark I still don't know how to water proof my hand

  • Why does he say Oi! so much?

  • Dang, Mark! Now I understand surface tension!

  • you are a good teacher but dont ever become one of those grumpy teachers

  • just wear a glove lol

  • 5:03 I do say 3

  • 50

  • i am going to go ahead and say astronauts weigh themselves by taking their weight and multiplying it by 6 b/c gravity is 1/6 the strength it is on the moon than on earth.

  • this is more than i learned from 9 year in school

  • 6

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