SCIENCE CLASS #4- How to Waterproof Your Hand
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- https://youtu.be/8aaXZDazPxs
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.
That moment you are actually sad there is no class on wednesday
Yeah, sammmeeeee
Oh yeah wednesday is april fools… hmmmmm
I could hack my sis as a prank
I just made the likes 112 and I’m dying inside
Kevin Luo :O
Instructions unclear: now I’m unable to wash my hands
*how will I defeat the coronavirus?*
L
@Elena Wetmore THATS THE SPIRIT
@Idress Alrashdan sorry mr.
@Sohamsta it’s okay I will like ur comment pro
Lol just remove your hands! Easy
Last time I was this early Mark was still at NASA
“it’s a beautiful Monday”
*Impossible*
School: closes
Mark: *hold my beer*
Also the soap is a dad to a daughter and a boy which are two molecules. Analogies 🙂
I don’t think Mark drinks. But I too dig the analogies. So good. 🙂
RoanStone lol “hold my beer” is a popular phrase to show someone going to accomplish something or do something
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!
Anyone notice the hot wheels track as the pointer 9:03
Everyone: WASH YOUR HANDS
Mark: How to waterproof your hands
Mark rober is a legend. He shall never be talked behind his back.
Lol
@Willie Bravo He also made a video showing how easily germs spread and why it’s important to wash your hands.
No No he’s got a point
@mehdi malekmohammadi it was a joke
Mark Rober: makes a video about washing your hands
Also Mark Rober: how to prevent washing your hands
The soap will take off the hydrophobic coating though.
@Kevin Luo science…fun
LOL
How to copy a comment after saying no to making it a meme
@Blarg I didn’t copy that comment, if you think about it we are both talking about different things
And also when I said no I was joking, damn
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!! 😀
The irony is that my uncle worked for nasa and said he had a ‘magic touch’ that could push away the pepper on the water
Mark is literally the best teacher ever, he made me loves science!
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!
@Mitchell Soap is amphipathic, meaning has a hydrophobic end and a hydrophilic end.
Only certain rocks can absorb water. Many rocks are porous and contain water in the pores, but don’t actively take up water. However, there is a type of ethiopian opal called hydrophane opal that can absorb water into microscopic pores.
Sodium is hydrophilic because it is an ion, and since water is polar, it will be attracted to the oxygen end of h2o. This is why salt dissolves in water. Water breaks the bond between na and cl.
You should do magnets
Better than my teacher
Mark Rober there’s class on Wednesday it’s a April fools joke
Cool! I can’t wait 😍
Instructions unclear: I am now able to walk on water.
Well you are always walking on water if you r in a pool cuz atoms never really touch each other, but yeah
This dude who literally worked for NASA to help build the Rover is now teaching us high school physics.
Imagine the NASA scientist dreaming of one day being a school teacher.
We don’t need to imagine, he’s right here! I also wanna be a teacher
After all teachers teach scientist to make them who they are.
What is this timeline?
How do astronauts weigh themselves in space? A space-ial scale 😀
Mark: No, you guys can’t hold hands.
Me: are you saying that water molecules have to go on quarantine too?
I love physics
No’one:
Mark: *Spends times helping kids learn on his own time and being a very geunine nice guy*
Mark: How to waterproof your hands!
