A while back I was eating lunch with
some co-workers and we were debating about just how far you would sink if you
jumped into a pool of these orbeez For example would it go up to your calf
or to like your waist or all the way above your head Everyone seemed to have
a different theory, in fact I asked about a hundred people and you can see how
much the guess is varied, so as a firm believer in the scientific method I
decided to test our hypotheses So I’m here today in the backyard of the
backyard scientist. so for the past six months we’ve been stockpiling these
orbeez in Kevin’s backyard and today it’s finally the moment of truth all right you ready for this let’s do it
so take a moment to guess in the comments below of how far you think we’ll
sink and then we’ll see if you’re right For the record I think I will sink to about
the waist, okay here we go This Feels so crazy This feels like its compressed on all sides but
it’s so smooth and like slippery So it looks like I was wrong by quite a bit
and we have to reject the null hypothesis So now what I decided to call
up my nephews you guys want to come swimming at my friend’s house in my
ongoing quest to be the favorite uncle only I might have forgotten to tell them
there’d be no water in the pool also that kevin was right there You guys ready to go swimming in this But before we go swimming in 25 million orbeez let’s talk about why I was wrong It has to do with buoyancy so here’s a riddle when
this ice melts will the water level go up or down as you can see here it
actually doesn’t change at all Archimedes taught us that you displace
your weight in water so this baseball weighs about 135 grams
and when I put it in water it will sink until it is pushed out 135 grams worth
of water at which point it’s in equilibrium and it floats and since the
waterline is about halfway up the baseball you know it’s about half as
dense as water and this is why scooby-doo quicksand is pure lies you
sink until you’ve displaced your weight in quicksand and since it’s about twice
as dense as a person you Bob like a cork about halfway down and it’s impossible
to sink so Atreyu relax your horse is going to float So I
will keep sinking in Orbeez until I have displaced my weight in Orbeez and since
they’re a little more dense than me and taking account the packing efficiency of
a sphere surrounded by water the fact that about 85 percent of me sank makes
sense I thought the friction between the balls
would play a bigger role which is why I guessed halfway so I was wrong but a lot
of times that’s more fun because that means the result was unexpected and you
learn something okay back to the pool Guess where my foot is So a huge thanks to Kevin for letting us
use his pool he actually also made a video we did eight crazy experiments
with a pool full of water balls so go check that out because his footage is
amazing as always I also want to thank Squarespace for helping to make this
video possible you guys know I’ve been using them to
build websites long before they offered to sponsor my videos it’s really easy

One like one prayer for the clean up of this!!! Lol
all i could focus on was how it looked like mark peed his pants
all i could focus on was how it looked like mark peed his pants
Having only watched one minute and 30 seconds so far, I guess a human will sink to thigh level, if vertical. That is my prediction.
Dude how you count it 25mill?
I don't see this answered below… what did you do with all these water balls when you were done? I mean, did you just leave them in the water? Take them out and let them dry? hahahaha. I can't for the life of me figure out what you might have done.
…
Waist
If I will grow up I'll be just like you doing awesome things and I want to do awesome things to!!!!??????????I'm a big fan
Mark roger is liTTTerally the scientist version of like mr beast or pewdz
Mark is such a firm believer of the scientific method that he says it at least once a video!
Head
Lol calm down your horse will float
I guessed shoulders
Mr beast watches this…
Dang it Chris! His is better
How powerful is this guys pool filter?
Haed
“IM ALIVE”
I think to the shoulders
All the way
I think head
Your horse is gonna float.????
cooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooool
Why can’t u be my uncle smh
If I did this I would never regret it
I literally want to be him
I wish i had Mark Rober as a uncel
Hi my name is silver and I love blue~ YEAH I LOVE BLUE BLUE BLUEEEEE
I love orbbez so much
He'll sink to the waist.
It would go to ur head
Hed
Soooooo, what did you do with the orbeez? Idk how to spell it, but I’m genuinely curious, you take them to the dump? Cuz that’s pricy, and multiple trips. Take them out, let them dry, and bury them? That would take a while and piss off the trees. I need to know
All
Half way maybe?
4:22 your 100% the least favourite uncle??
maybe to the head then the wast
You will go down to your shoulders
Who's rewatching
wish he was my uncle
2.42 he is 1 ounce off
Enough with science in every video please?
At head
Anyone else kinda traumitised by the hoars in quicksand
4:45
LOOK AT THIS DUUUUUDE
up to your waist?
Orbeez heaven T^T
Is you blind that said 124 not 125
I envy his nephews
Back when nipples weren’t illegal on YouTube
4:22 hm… weird.
Where did Kevin go
The real question is how long did it take to clean it?
it's crazy how I was here the first hour this was uploaded
Who else thought this was was a mr beast video
3:10 Oh come on Mark. That was a very emotional scene in The Neverending Story.
What relax your horse gona shink???
I think he will sink all the way
Me:*sees this video* also me:*Did they take 6ix 9ines hair into a pool?*

M
I think so till chest
MR BEAST AND ROBER COLLAB

"Do you sink or float?"
We all float down here.
Just bellow your head
Mr beast is quaking
.
Head
60 feet

I love ur vids keep it up
Head
Like here???
4:26 wait what
You sounded like IT, ‘your horse is gonna float
Lengthwise should stockpile quicksand
Half way
i thought it would get to my head and i was right.
idk
Mark Rober: 25 million Orbeez
in my pool!
Mrbeast: that's cute
Head
Curiousity level: 25,000,000
I assume up to your neck, but maybe it depends on your weight, and body shape.
The real question is how do you clean it up?
I saw 25,000,001
4:30 soldiers… ATTACK
I wonder how long that took to clean up
There goes the backyard scientist out the pool
