the volumetric displacement of the object is lower than that of the cargo ship, so when the ship discharges heavy cargo into the sea, the ship's draft decreases, displacing less.
what do you mean? it was very clear in my opinion, just takes understanding of buoyancy and physics to figure out if it's true or false. Yes, a dense object doesn't necessarily mean an object denser than water, but I think the video gets rid of that problem.
The mass and total covered surface area of an object determines how much displacement it will cause. Since a boat with the tungsten block is able to cover a good amount of surface area, while having a high density object with a lot of mass to push the boat down further, it will displace a larger volume of water than either of the two separately. The tungsten block does a great job of displacing the water while in the boat due to the size of the boat and the force of gravity on the heavy tungsten block. However, once you separate the boat and the tungsten block, the level of the water will decrease drastically due to the fact that the tungsten block is extremely dense, allowing to to contain all of its mass in a much smaller, more compact form factor. The boat, on the other hand, is far less dense, meaning its structure is much larger and more buoyant than the block. So, depending on the shape, size, and weight of the boat, it will be held up by the water's natural surface tension. The dense tungsten block will break the surface tension easily since it is both heavy and has a small surface area but will only be able to displace water equal to its volume, not its mass. You could replicate this with a bowl of water, a piece of cardboard shaped into a boat shape, and a rock
The water level goes down a bit because when you take the heavy cube out of the boat and put it in the water, the boat becomes a little lighter. When the boat is lighter, it doesn't need to push down on the water as much to stay afloat. So, when you take the heavy cube out, the boat rises up a tiny bit, and that means it's not pushing down on the water as hard, which causes the water level to go down just a little.
I really had no clue which was fake on this one I just want to make an apology for everything I have done. You guys were right and I was wrong. Screw you. MOOOOOOM IMMM FAMOUUUSSSEEEEE
What happens is the block brings the boat down including it's mass then when released the boat goes up so it is down than up due to water displacement being the boat goes up revealing for area for the water

Question then. If you were already on the boat with that large mass(as pictured) wouldnt the water level already have displaced the weight of the mass ? Therefore no displacement should be observed when throwing the mass into the water ?
@@AngyBeaverwhat displaces the water is volume of the cube, not the mass. Buoyancy prevents the objects full volume from being reflected in the waters level
For all who don't know the heavy object was floating so the water was up by its mass but when it got dropped into the water it made water go up by its volume And since it is really heavy the amount of water pushed by its weight is bigger than the amount pushed by the volume
@@Loooooooooooool1it isn’t any bigger while it’s on the boat, but it pushes the boat down, meaning more total volume of matter is below the water while the object is on the boat
@@dobarek4548heavier objects will displace more water in a boat, but mass has no effect in the water itself (aside from density determining if the object sinks). If an object is dense enough, the space occupied by a portion of the boat with the object on board can be more than the combined volume of the object itself and the submerged portion of the boat without the object on board
For the boat question, I always heard it asked as an anchor being thrown overboard since that is a dense object commonly found on boats. The way to solve questions like this is to think in extremes. Imagine your anchor is made up of a neutron star (in other words, the densest stuff in the universe outside of a singularity). It would weigh millions of pounds and make the infinitely large boat displace a ton of water. However, it still has the same volume as an ordinary anchor, so the boat would rise up higher in the water after it is thrown overboard.
You don't need to use salt to get that effect you just have to have really good timing when grabbing them out of the freezer. My dog loves it when I do this for her
Yeah, I feel like the salt was entirely irrelevant to the actual phenomenon there. Salt lowers the freezing point in water because it interrupts the necessary structure for water to crystallize. The only thing that needed to happen in order for the water bottles to become below 32F was use ice that was much colder than that. Not a fan of the deception in this video.

oh yeah you're right because the weight from the cube is pushing the whole volume of the boats hull down. not just the cube itself, displacing more water.
@@LepaLadva-mb2ykyes always. That’s how boats work. The weight of the boat in total (including everything in it) must be displaced by the equivalent weight in water. Since the object is denser than water, it displaces less when dropped in, because now it displaces water by volume. The volume of water displaced is less than the weight of water needed to displace to float it
@@hd4thehlls I think it varies with density, though it’ll never displace less water after dropping, but it theoretically could, with low enough density, displace the same amount either way.
When you have the object in a boat, it displaces it's WEIGHT in water (1to cube will displace 1to worth of water while on boat). If it is thrown into the water it only displaces water equal to it's VOLUME (a 1cbm cube will displace 1cbm of water).
I instantly knew the first one was wrong because wood is less dense and could displace more water with with less weight, if you throw off a heavy object then the boat would rise and all you have is an incredibly dense object that will barely displace any.
The first one is worded wrong. It just asks if the water level rises. Not if the water level on the boat rises. So the first one is right too... If you are floating on a "boat" in a above ground pool that has water up to the edge of the pool then drop a dense object into the pool the water will spill over the edge AKA rise. EDIT: Never mind. I get it. It's that the weight in the boat displaces the water equal to the water displaced when it is dropped in.
you still have it wrong. The weight it displaces when in the boat is GREATER than the water it displaces when submerged. not equal to. That's why it sinks in the first place. when its on the boat it displaces a volume of water equal to its mass. when it is dropped in the water it is only displacing an amount of water equal to its volume. Given that Tungsten is significantly more dense than water, when it is on the boat it displaces significantly more water than its volume for example lets take a 1 in^3 block of tungsten. A 1 in^3 (16.4 cm^3) (of tungsten it weights .62 lbs (281 g) throwing it in the pool would just displace its volume of 1 in^3 to float it has to displace .62 lbs of water. since it will float when on the boat because the boat is floating it putting it on the boat will displace .62lbs of water. water has a density of 0.036 lb/in³ (1 g/cm^3) so to displace .62 lbs of water it has to displace 17.2 in^3 of water. so putting it on the boat displaces over 17 times as much water as dropping it in the pool, since dropping it in the pool will only displace 1 in^3 of water. @@GhostOfBillCooper
Another way of thinking about it that makes more sense. Imagine you have a weight the size of a pea that weighs a million tonnes, it’s incredibly dense. If you dropped the pea sized weight into the water it would make the water level rise by the volume of the pea - hardy anything. Now let’s say you have a very large empty wooden barrel. This barrel would normally float on top of the water, as it contains mostly air, but if you put the pea sized weight inside it, it would make the barrel sink, displacing the whole volume of the barrel, which is a lot more than the pea. Now if you reverse the process like you see in the video, you start with the barrel being sunk in the water, and then you take the pea out, so the barre starts floating, and the water level goes down
If you put an object much denser than the density of the water into the water from a boat on that water, the water level will go down because the dense object isn't displacing as much water as it was while it was on the boat.
The TL;DR for #1 is because when held up by a boat, the block displaces water by its weight. When it is thrown into the water, it displaces water by its volume. By definition, if it sinks, it displaces more by its weight than by its volume. Therefore the water level goes down. This also makes sense because otherwise, it would imply that you could pump water essentially for free, breaking thermodynamics.
Makes sense, but he did NOT specify this (he just needed to give the weight and size of the object) he had to say that for me to know. Thank you, though, for the explaination :)
Tungsten cube's downward pressure was lesser when it was separated from the large area of the boat to push down weight, so actually the boat raised and the water lowered.
The boat one is explained because when a heavy object is floating in a boat, the boat has the displace it’s equivalent weight in water. So for 1 kilogram it needs to displace 1 liter of water. But if your object has more density than water, then it’ll displace less water by being submerged, since now instead of using the boat to displace water to keep it above the surface, it’s simply displacing it’s volume.
Not only will the water level in the first case not rise, it will actually fall since the displacement of a boat is an effect of its mass but the displacement of a sunken object is an effect of the volume. The density just defines whether it floats or not and is completely irrelevant.

I haven't seen the video explaining the Tungsten thing yet, but I assume it has something to do with the boat having a wide area and having to displace more water to stay boyant when loaded. Just a guess though.
Finally, one that makes me feel smart for getting the answer. I knew roght away when hou explained the forst scenario that this is not how bouyancy works.
I knew from the beginning because buoyancy is a mass displacement whereas an object sinking is a volumetric displacement 🤣 Also, my dad asked me that one time so it’s stuck in my head forever.
Let's say you have a very heavy anchor the size of a pill. The more weight that is on a boat, the more water it is displacing, right? Now when that pill anchor is thrown off the boat, the boat displaces, say, half as much water as it was before, while the pill anchor is displacing the volume of a pill. The amount of displaced water is now half as much as it was before, plus the pill anchor's volume, and water level is proportional to water displaced, so the water level is lower. A similar principle applies to more realistic situations too, but explanations work best with bigger numbers and extreme circumstances.
@@heysiri3327 I think it's because most people just assumed the only reason the boat is there is so he can get there in the theoretical situation, it seems like a trick question that more people would get if the facts were clearly presented
@@notlegoguy2511 It might not even need to, because even if EVERYONE on Earth jumped at roughly the same spot at once, the Earth move by, like, what, a few micrometers? I forgot, someone did the calculation and it is ridiculously small.
Im guessing the tungsten weighting down the larger surface area of the boat into the water causes more water to be displaced than if the small surface area of the tungsten was by itself in the ocean.
For those who don't understand why A was the false one, it has to do with the laws of water displacement. Everyone knows that if something sinks in water, then it will displace an equal volume of water. But what's less famous is that if something floats, it'll displace an equal mass. For example, an ice cube has about 90% the density of water. Therefore, if a 9 gram ice cube is placed in water, it'll be about 10 cubic centimeters, but it will displace 9 cubic centimeters of water. While the tungsten is on the boat, it's less dense than water, because the boat floats. But then, as soon as the tungsten is dropped in, it's more dense. And because the mass is greater than the volume (tungsten's density is almost 20 grams per cubic centimeter while water's is defined as 1 gram per cubic centimeter), there is less water being displaced, because now instead of 20 grams (therefore 20 cubic centimeters) per cubic centimeter of tungsten being displaced, it's just a cubic centimeter per cubic centimeter.
No, that's literally just not why lmao. The ice cube part is true because the ice dissolves into the water. The tungsten is just weighing down the boat, which has a higher surface area than the cube of tungsten, and therefore displaces more water.
A is definitely true. Yes, it’s in the boat, but to be fair, that means nothing for how much water it’s displacing while it’s in the boat, since the boat can cary a lot of weight without changing how much water it displaces (like the penny boat thing), meaning that even though the boat will displace less water upon the object leaving it, it is up to how the boat is designed to determine if more or less water is displaced. For the ice chest(c), it’s literally that ice bottle trend, just he’s pouring out the water, rather than hitting the bottle. And for B, I think it’s real, as the water will keep the part of the balloon near the flame cool enough that it won’t immediately pop the balloon. I think the popping is due to heat, as my younger cousin has been popping Bloons by putting them under lights for a long enough period of time. Either way it’s transfer of energy, which the water will slow down since it will take longer for the water temperature to change. Therefore this is a rare d: all of the videos were real. I… how???
when the block is in the boat, the mass of the block is technically floating on the water. its weight is being completely counteracted by the buoyancy force (Fb). Fb = DVg, where D is density of liquid, V is displaced volume, and g is acceleration due to gravity. since D and g are both constant, the only way for the metal block to have that increased buoyancy force in the boat, is if the volume of displaced fluid is higher. in short, the only way for an object with constant mass to float is for it to displace more volume in the water. therefore, simply because the block is floating while it's in the boat, we *know* that it has to be displacing more volume. thats the reason *why* it's floating.
At first i thought the water oke was worded wrong but it makes sense now. The block thats heavy pushes the boat down onto the water displacing far more water than if it was by itself in the water. If you dropped it from air it would technically make the water rise but swapping it from boat to water makes it displace less water because it no longer has the boats help.
I have a small refrigerator at work with a freezer and refrigerator section. If I put a water bottle on the door very close to the freezer section it will remain liquid but have the same freezing effect shown in the video. It was really odd to see the first time but now I am used to this..

water has a density of
0.036 lb/in³ (1 g/cm^3)
so to displace .62 lbs of water it has to displace 17.2 in^3 of water. so putting it on the boat displaces over 17 times as much water as dropping it in the pool, since dropping it in the pool will only displace 1 in^3 of water.

@@HedgeHogDino13 you're welcome! He was definitely a bit obtuse in his wording, by saying "a large dense object" instead of "the object sinks."
I feel like every time the one of which I’m 100% positive that it’s true is the trash
It lowers the water level since the dense object has less area to displace water with its weight.
Tungsten cube's downward pressure was lesser when it was separated from the large area of the boat to push down weight, so actually the boat raised and the water lowered.
The boat one is explained because when a heavy object is floating in a boat, the boat has the displace it’s equivalent weight in water.
So for 1 kilogram it needs to displace 1 liter of water.
But if your object has more density than water, then it’ll displace less water by being submerged, since now instead of using the boat to displace water to keep it above the surface, it’s simply displacing it’s volume.
But it takes up more space.
Riiiight I thought it was just generally speaking about putting something into water.

Oh I get it now it’s off a BOAT! I was thinking more free form
I officially know nothing, my mind is blown and my ego is shot. Incredible.
Totally fucked that one up lmao
Not only will the water level in the first case not rise, it will actually fall since the displacement of a boat is an effect of its mass but the displacement of a sunken object is an effect of the volume.
The density just defines whether it floats or not and is completely irrelevant.
This was the first one that got me
This one was "easy" because I knew the last two were true. Otherwise I probably would have been stumped lol

@@The_Watcher_0 number 2, assuming that “ocean unicorns refers to narwhals.
This is the first time I've actually known which ones were true beforehand.
I haven't seen the video explaining the Tungsten thing yet, but I assume it has something to do with the boat having a wide area and having to displace more water to stay boyant when loaded.
Just a guess though.
Yup
i have a cameo in this video lmao
Lol
Finally, one that makes me feel smart for getting the answer. I knew roght away when hou explained the forst scenario that this is not how bouyancy works.
on the boat it displaces based on its mass, in the water it displaces based off its volume
I knew from the beginning because buoyancy is a mass displacement whereas an object sinking is a volumetric displacement 🤣
Also, my dad asked me that one time so it’s stuck in my head forever.
I
1 really seemed true tho
Let's say you have a very heavy anchor the size of a pill. The more weight that is on a boat, the more water it is displacing, right? Now when that pill anchor is thrown off the boat, the boat displaces, say, half as much water as it was before, while the pill anchor is displacing the volume of a pill. The amount of displaced water is now half as much as it was before, plus the pill anchor's volume, and water level is proportional to water displaced, so the water level is lower.
A similar principle applies to more realistic situations too, but explanations work best with bigger numbers and extreme circumstances.
@@heysiri3327 I think it's because most people just assumed the only reason the boat is there is so he can get there in the theoretical situation, it seems like a trick question that more people would get if the facts were clearly presented
@@heysiri3327but in this case the anchor isn't in the water yet so it is kinda like a cork in water
I might be wrong tho
@@Rzedits3445 Did I use the wrong term? My bad, but I'm happy so long as my point still got through.
And here I thought the whole point of a boat was that it doesn't displace as much water as the materials contained within.
You know what’s trash? The haters! 😂😂😂
Good thing i knew that the 2nd and 3rd was real because the 1st one convinced me
The boat one had the same idea as “when you jump you push the earth down”
well technically speaking.... you do apply an force that has an opposite yet equal reaction, however, the earth just happens to be fucking massive
@@quertyVAT Even if it did technically go down all It'd have to do is just stabilize in orbit.
@@notlegoguy2511 It might not even need to, because even if EVERYONE on Earth jumped at roughly the same spot at once, the Earth move by, like, what, a few micrometers? I forgot, someone did the calculation and it is ridiculously small.

LOL I GOT IT RIGHY DURING THE FIRST ONE BY GUESSING
Im guessing the tungsten weighting down the larger surface area of the boat into the water causes more water to be displaced than if the small surface area of the tungsten was by itself in the ocean.
For those who don't understand why A was the false one, it has to do with the laws of water displacement. Everyone knows that if something sinks in water, then it will displace an equal volume of water. But what's less famous is that if something floats, it'll displace an equal mass. For example, an ice cube has about 90% the density of water. Therefore, if a 9 gram ice cube is placed in water, it'll be about 10 cubic centimeters, but it will displace 9 cubic centimeters of water. While the tungsten is on the boat, it's less dense than water, because the boat floats. But then, as soon as the tungsten is dropped in, it's more dense. And because the mass is greater than the volume (tungsten's density is almost 20 grams per cubic centimeter while water's is defined as 1 gram per cubic centimeter), there is less water being displaced, because now instead of 20 grams (therefore 20 cubic centimeters) per cubic centimeter of tungsten being displaced, it's just a cubic centimeter per cubic centimeter.
No, that's literally just not why lmao. The ice cube part is true because the ice dissolves into the water. The tungsten is just weighing down the boat, which has a higher surface area than the cube of tungsten, and therefore displaces more water.
@@GustavRex So the consequence of what they explained?
The easiest way to see that number 1 was fake is the Fakt that it is animated, while the other two are actually demonstrated
So you expect him to buy a tungsten cube which would be expensive and go into the middle of the ocean for a CZcams short?
@@N36C Of course! a little bit more effort won´t hurt XD
@@N36C other bodies of water exist, he could go to a small lake or something and then get the cube out afterwards
I remember the second being true because i tried it in grade 3
The ice molecular grid gets seperated from the salt, resulting in the cold water to make it even more freezing
Of course its the first one. Density doesnt affect the rising of water, size does.
It doesn't matter how heavy an object is, only its volume.
so if wooden ships swim, a same volume ship made of lead would also swim
Is this a troll question? This is a troll question, I don't need to answer you.
The first one was a question I got wrong on a physics exam. I now learned my lesson.
i thought bro was gonna put a body inside the cooler
A is definitely true. Yes, it’s in the boat, but to be fair, that means nothing for how much water it’s displacing while it’s in the boat, since the boat can cary a lot of weight without changing how much water it displaces (like the penny boat thing), meaning that even though the boat will displace less water upon the object leaving it, it is up to how the boat is designed to determine if more or less water is displaced. For the ice chest(c), it’s literally that ice bottle trend, just he’s pouring out the water, rather than hitting the bottle. And for B, I think it’s real, as the water will keep the part of the balloon near the flame cool enough that it won’t immediately pop the balloon. I think the popping is due to heat, as my younger cousin has been popping Bloons by putting them under lights for a long enough period of time. Either way it’s transfer of energy, which the water will slow down since it will take longer for the water temperature to change. Therefore this is a rare d: all of the videos were real.
I… how???
when the block is in the boat, the mass of the block is technically floating on the water. its weight is being completely counteracted by the buoyancy force (Fb). Fb = DVg, where D is density of liquid, V is displaced volume, and g is acceleration due to gravity. since D and g are both constant, the only way for the metal block to have that increased buoyancy force in the boat, is if the volume of displaced fluid is higher.
in short, the only way for an object with constant mass to float is for it to displace more volume in the water. therefore, simply because the block is floating while it's in the boat, we *know* that it has to be displacing more volume. thats the reason *why* it's floating.
you’re incorrect,if u place an object into a boat, the boat will displace the same amount of water, no matter what the shape of the boat is
how tf is the 3rd not Fake 💀
You can just use a freezer you don’t need the whole setup he got
I can't wait for D to work
I thoglught he said the water lev3l would raise not lower lol
I always just watch the intro because its so satisfying
This video made me want a psychologist.
I could say many things here but i think thats enough
The boat rises because the dense object displaces more water than its own weight. It's all about fluid dynamics and displacement!
“Ice chest” where from we called a Cooler, ice chest sounds COOL though
Simplified version of the tungsten thing: the tungsten got a lil thirsty and drank some water
C how to actually do it is to leave Fiji water in the freezer for two hours only and this only works for specific water so that’s why we use Fiji
I feel like it's D. No was fake, but maybe c
Obviously it was the first! He showed the other ones so they had to be true.😂
The first one was a drawing the rest was a demonstration of the things you talk about actually working
I watched the video for the first one and it makes no freaking since
I’ve watched so many of these videos that all I’m wondering is how on earth did he make the intro
Bro taking 10 tries to do the kinking of the paper ball into the dustbin
Me taking a dive to make the water level rise
If you want to throw something overboard The water level would rise but it would go down compared to the boat
"mom where's my water bottle?"
At first i thought the water oke was worded wrong but it makes sense now. The block thats heavy pushes the boat down onto the water displacing far more water than if it was by itself in the water.
If you dropped it from air it would technically make the water rise but swapping it from boat to water makes it displace less water because it no longer has the boats help.
Ok but then that ice experiment looks really cool
I have a small refrigerator at work with a freezer and refrigerator section. If I put a water bottle on the door very close to the freezer section it will remain liquid but have the same freezing effect shown in the video. It was really odd to see the first time but now I am used to this..
Makes sense but definitely didn't have enough information to guess that
i encountered the first "fact" as a phycics question before
