This ice cube is too heavy 

It sounds like a bad joke: "How do you make a heavy ice cube? Use heavy water"

"I'm not fat, it's just water weight" The water:

for those who don't know the D in D2O stands for Deuterium which is a hydrogen isotope

"Did you add something in my drink?!?!" "No sir, thats our heavy ice cubes"

“this one’s kinda special” i get told that ever so often

Me when I see my ice cubes fall to the bottom of the water: *panic*

Can i have a glass of water? Sure Light or heavy? "Visible confusion"

Titanic: ice cube the sequel

"Can I get light ice in my soda?" "I'm sorry, we're out of light ice. We only have heavy ice now"

"Can I get some ice cubes on my drink, please?" "Heavy or light?"

“If your ice cubes in your drink don’t float, don’t drink that drink”

the ice cube doesn't know how to swim yet, you should teach him

"I think its pretty cool" icy what you did there.

"Waiter, my ice is broken." "That's because we use crushed ice, sir." "No, look."

Nile gonna make a mini reactor like that kid in his parents garage.

I love how you can see the liquid sinking as it melts.

‘how do you make square balloons?’ ‘blow square breaths’

"Bro why are you so HEAVY!" "Its because im special"

Most people don't know that heavy water is what gave Jay Garrick's Flash his superspeed

"This is just a regular ice cube... and if I drop it in water... it floats." I was really hoping this would be the whole video. Standing ovation. I would leave a like right there.

For anyone wondering, heavy water is basically H20 but it uses hydrogen's isotope which has one neutron (instead of the regular hydrogen atom which has no neutrons) known as deuterium which doubles the mass of the hydrogen atoms making the compound 11% denser

“Why are my ice cubes not floating?” “Oh, I added heavy water” “But there ice cubes- nvm”

He’s advanced past normal chemistry, now he’s on his fusion reactor arc

"this is just a regular ice cube." Me: "HE HAS REGULAR THINGS?!"

“I used heavy water” Everyone: *loses brain cells*

That is neat now bottoms up.

The fact that you can see the heavy water sinking off the ice cube as it melts is pretty neat too

"How do you like your water?" "Heavy."

"It's all cool untill you realise that the heavy water costs *100$/liter almost* "

The ice cube looks like a diamond

Did u poison my ice cubes!?" No sir thats our heavy water

When he said ‘heavy water’, I thought he was joking.

"it sinks because it's made with heavy water." Well uhm, that explains a lot..

Bro ice cube has a heavy Poison. Bro has an heavy killer in his closet

on the other hand, if ur ice cube dosent sink it means theres also poison

“Can I get a Pepsi with heavy ice?” The waiter: “wtf”

“This is a regular ice cube and when I put it in water it floats” *clapping intensifies*

“And I think that is pretty cool” Good for you buddy

Ice Cube is having identity crisis over this

I like how you can see the heavy ice cube melting and that liquid sinking to the bottom

*heavy water is discovered in 1785* People before 1785: "If it floats, it's human. If it sinks, it's a witch."

Oh I thought I'd seen this before but it was a clip! That's a nice part!

The Ultimate Human is talking about hydrogen water for physical conditions.

Who else thought he was gonna violently throw the regular ice cube across the room

“Today was a heavy day.” - Ice Cube

D2O (Ditrium Oxide) is heavy water made from Ditrium which is an isotope of hydrogen. When it forms water (heavy water) with oxygen, the water is a little bit thicker and denser than normal water. Ice made with Ditriumoxide is also denser than the normal ice. Nice science tip. I love that. I wish you all the best of luck.

“I’m still thirsty, but my stomach feels weighted already!” “Whoops, accidentally gave you my heavy water!” “What.”

“This isn’t some weird ice cube making trick. I just used heavy water” So a weird ice cube making trick.

"I want a coke light" gets a completely new meaning.

Watching the melt flow off the ice cube is pretty cool too.

What's cooler is that you can see the heavy water melting off the heavy oce underneath it, making a hazy effect in the water

I like how you can actually see the heavy water flowing off it as it melts

D stands for Deuterium. Basically hydrogen atom with an added neutron. Risibly so, but denser than regular H2O. Called "heavy water", it's commonly used in nuclear reactors. Add one more neutron to Deuterium and we have Tritium, which is straight up radioactive.

It's cool watching the fluid melt off of it and sink.

I learned a little bit about heavy water from the neutrino experiments, so learning more about it is really interesting.

Man: "Bring some ice cubes" Waiter: "heavy sir?" Man: "excuse me?"

Fun fact: Heavy water is also used in Nuclear Reactor as a moderator, So chain of reactions happening can be controlled.

"This on other hand" no no no bro it is the same hand

I'm amazed and a bit envy now. You just make the tricks that every science nerd preteen guys wanted.

"I am heavy water guy, and this is my water gun. It costs 400,000 dollars to water this gun for 12 seconds."

So in other words, if you put it in heavy water, it would still float

Deuterium is my favorite ice-otope 😂😂

"Hey why is my ice cubes sinking?" "You made it with heavy water"

I love how as the heavy ice cube melts u can see the heavy water sinking as well

For anyone wanting to know, you can drink heavy water, just not in large quantities without having symptoms of dizziness and low blood pressure

Put that heavy cube in heavy water it will also float!!

Why is your channel better than science class

You can even see ripples of the heavier water melting off of it, and drifting down. Neat.

"Look! I've bought water dumbbells! I'll fill it with water" "It's too light, better use heavy water." "what"

That 1st ice cube is a beautiful individual bro, it deserves better, no wonder your single

Alternate title: Special ice cube is rejected from ice cube society because he doesn't know how to float

Almost every NileRed short: “And I think that’s pretty cool”

the way it rocks back in forth in the water reminds me off the floating rocks from journey to the center of the earth

I think it's cool that due to the different diffeactive indices, you can see the D2O melting in the H20O

"Heavy Ice cubes are made of heavy water" This wood floor is made of wood.

"heavy ice cubes are made of heavy water." "ah yes, the floor here is made out of floor"

Moral of story it is was it is

Caseoh as an ice cube:

"This isn't because of some weird, ice cube making trick" Proceedes to explain a weird, ice cube making trick

For anyone wondering: yes, you can drink it. Don't drink too much and over a longer period of time tho, as it can fuck up your blood pressure.

Moral ice cubes sink to the top and heavy ice cubes float to the bottom

"DID YOU ADD SOMETHING IN MY DRINK?!?!" "NO SIR, THATS OUR HEAVY ICE CUBES"

"Excuse me, waiter, my ice is too heavy" "Fuck you" "....ok thank you"

For anyone wondering, the D in D2O stands for Deuterium. Deuterium is basically a Hydrogen atom, but with 1 neutron in its nucleus instead of 0. This makes the total weight higher (just double, actually. Weight of hydrogen is 1 amu due to just 1 proton. Weight of Deuterium is 2 amu due to 1 proton and 1 neutron) but doesn't increase volume, hence increasing the density. These kinds of atoms where they're of the same element (same number of protons and electrons) but differ by the number of neutrons and hence differ by Atomic weight are called Isotopes. Hydrogen has 3 Isotopes: Protium (the normal one), Deuterium (with 1 neutron), and Tritium (with 2 neutrons).

It is also (supposedly) ionic-neutral which makes it great for cooling thermonuclear reactors because it doesn't want to form hydrogen bonds as much, making it flow easier

The waves coming off of that is dope

For those wondering, the water is made using an isotope of hydrogen called Deuterium. Atoms are made of positive heavy protons in the core of the atom, and tiny negative electrons that orbit the core. There are also neutral neutrons in the core that are a little heavier than protons. Typically for lighter elements, the number of protons, neutrons, and electrons is equal. Oxygen for example most often has 8 protons, 8 electrons, and 8 neutrons, for a total weight of 16 (electrons don't really contribute to the weight). Hydrogen often doesn't have any Neutrons and is just one proton and one electron. So when you make H2O using two hydrogen atoms and an Oxygen atom, the weight of that molecule is 16+1+1 = 18. Deuterium is a hydrogen atom that also has a neutron for a total weight of 2, so when you make D2O, you get 16+2+2 = 20, or about 11% heavier. Now adding neutrons doesn't really make the atom any bigger, just heavier, which is why the ice sinks.

you can see the slightly heavier D20 that is melting off of the heavy ice sinking to the bottom, because it is also optically denser and is refracting light, really cool.

That is in fact, pretty cool.

I like that you can see the melted D2O mix with the water and fall to the bottom of the beaker

Finally! ...we can hit the Titanic with a second iceberg!

For those curious, D stands for Deuterium. It’s an isotope of hydrogen that’s around twice the mass of a usual hydrogen isotope.

The same applies if you freeze water in a copper container! When I was in school we had a project in practice for 2 years to find a way to prevent water from defrosting at temperatures below 90 degrees, and we only acquired ice cubes that did not begin to defrost until they reached temperatures of 82 degrees, some classmates believed that the volume of the water had something to do with it.

Finally, we figured out what Meshuggah like in their lemonade!

It's really weird seeing the water flowing down as it melts off the ice cube

"Yo why is your metal guitar so heavy, bro?" "Cuz it's made of heavy metal of course! 😤😠"

I want my water heavy

You can see the heavy ice cube melting and the heavy water sinking, that's really cool!

Doctor: I’m concerned with your recent weight gain Me: Yeah I’ve been drinking heavier water

I love how you can see the heavy water melting into the classic water
