- When you pop a water balloon underwater does the water stay in one place or spread out? If we dye the water we can see how a water balloon behaves when it is popped under water and how that behavior changes when the water is hot or cold. The experiment see how density of liquids changes with temperature and how diffusion rates change with temperature.
Here are some more fun experiments!

0°C water is called ICE
@@caliguladeux Water is actually not necessarily ice at 0°C!
When ice is warmed to 0°C, the temperature stays at 0°C while the ice melts (despite heat constantly being applied to it), and starts rising again only after the ice has completely melted.
This is because *phase change takes energy*, and at 0°C, energy from the heat is used to convert the water from a solid state to a liquid state.
So both solid and liquid forms of H2O can simultaneously exist at 0°C :>
I like your voice. It’s relaxing 😌
@@helenchen6308you can't forget supercooled water
Put the full video in the link below the shorts
The movement caused by the collapsing of the balloon is "stirring" the water.
I think it also matters that the baloon pops from the top to the bottom. The shrinking balloon skin pushes the water upwards initially but cold water eventually sinks while hot stays on top.
You didn't really answer the question the video is talking about, diffusion. What he wanted people to see is that temp is a factor in the rate of diffusion. Idk wasn't the greatest demonstration.
And the "stirring" would be in part of the balloon but things want to be equal so it's going to spread till there are equal parts throughout obv temp will effect this but eventually it will reach an equilibrium
I think an improvement to negate a chunk of that effect would be to, instead of using a balloon on its own, stretch a balloon over a shotglass (putting the balloon over the shotglass while both are submerged in the water being used to fill it), then keep that in place while a rubber band or something similar is used to tightly wrap the rubber to the sides of the glass so when the membrane is punctured only the part at the top of the shotglass will rip and there is no pressure from the other side pushing in that direction, reducing the force towards the direction of the puncture and also minimizing how much motion is added to the water by the rapid movement of the popping balloon.
This would also be modifiable to allow placing the shotglass at different areas in the water, for example using a magnet in the base to position it sideways at the side of the larger beaker.
You must have passed elementary school.
The friction between the balloon rubber and the liquid really matters!!
The way hank commented and people don’t even realize it, is concerning

I think that the difference in diffusion is due to the density difference.The more denser cold water diffuses towards down while the less denser hot water to up.
Yea ur cool!!
The reason it still pops and don't hold it's shape is because the balloon is still being stretched. Being underwater don't change that.
Bleeding oath. I thought this was very intuative as well..
I mean a balloon filled with air doesn't hold its shape when popped and surrounded with room temp air..
More specifically the water inside is compressed
@Jack B 🇺🇦 what do you think is the cause of the balloon stretching? It's compressed BECAUSE the balloon is stretched, not the other way around.
Yea... After all, an air-filled balloon will also pop when punctured in air.
@@MrT------5743 all liquids are incompressible, its the movement of the balllon snapping back to it's non-stretched state that creates currents in the water
What do you think would happen if we had a salt water filled balloon? Did you notice any cool observations?
Fun Steel Wool Experiment (short)

What a explaination 👏👏
Maybe the cold and hot ones will be more separated
Ooh what about a balloon filled with colored oil?
Try exchanging the dyes, it could be that they affect the way it spreads.
(Probably not but it would be an interesting control experiment.)
The elastic movement of the balloon popping will move the water and effect the dye movement. If the water was still and the balloon just "disappeared" then I recon the dye would hold its shape more.
“What have you noticed?”
That I finally know why I failed my science test.😢
And you're still alive mahhn you're lucky then😂
You speak with the cadence of reciting a Dr Seuss book, and I love it.
The hot water rises, and cold water settles. The same happens even with air.
Until you get ice.
Pretty much everything 😄
But noticed the room temperature water is diffusing to the top first before it evens out.
Turns out being put in the balloon create additional pressure exerted by the stretched balloon, thus increasing the temperature of the water ever slightly higher, that's why it diffuses to the top first before it evens out.
did know hot water rises in air
this video is the most complicated way of describing something so simple

Guys, water and ice coexist at 0°C. It's the melting point, it can happen with any pure material. Same at boiling point (but with vapor and liquid). At really low pressure and almost 0°C, water reaches triple point where all three phases can be seen together. It's called phase equilibria.
Amazing! Cold and salty water sinks. You just explained the engine of the thermohaline circulation currents.
The balloon breaking obviously creates a force that helps mix and disperse the dye fairly quickly. If you could somehow make the balloon disappear without a force involved it might stay in place for a bit longer before diffusing.
his voice is so soothing
You have a very audio book voice, or a “safe and fun science experiments you can do with your kids” voice. Very relaxing
It looks like the red dye made a heart before fading.
Also, your voice is very calming it sounds like the Bob Ross of science. 🤟🏾
The latex still has tension, and the turbulence caused by its collapse still mixed the water
Thank you for uploading this video are so grateful from this video because tomorrow is my experiment of matter on our surroundings
😅😊
I noticed hot goes up and cold goes down. Basic science learned in elementary school....
Do you believe everything you're told at face value?? I like seeing evidence for my life axioms. I appreciate that people do this shit instead of just pointing and having a remedial English computer voice read me Wikipedia about how they found Davy Jones locker or whatever
@@owlredshift uhh my guy the atoms around you are doing this right now. Calm down flat earther xD
People are so stupid now that I can't relate with them anymore.
can you comment something related to Bob's comment? wtf are you doing in his comment?
anyway, you should also notice that they didn't mix at all, each one took its own place
Not quite. 4°C (39.2°F) is the densest temperature of pure water. Water warmer or colder than 4°C (39.2°F) will "float" in room temperature medium of water.
Thank you for doing this important work.
Thank you for actually showing the whole experiment in one short!
i love the color coding,, thanks !
I noticed you forgot to factor in the force of the balloon popping making the water move around in the beaker.
Bro i had a science test on this today and you just confirmed i got this specific question wrong 😭
How could you get it wrong? This is sixth grade physical science. Hot fluids lose density and rise. Cold fluids gain density and sink.
Proof that hell is an icy cold mess and heaven is a hot haven
Good way to explain how temperature rises and falls (and even a little diffusion i think.) Keep up the good work
Basically works like a normal thermometer, hot usually is upwards, cold is usually downwards and then warm/room temperature is usually in the middle
spot on
It probably wouldn't change anything, but I think the optimal way to do the room temp water balloon is to fill the balloon, set it in, then leave it for an hour or two. Come back, then pop it and see how it behaves. Maybe nothing changes, but then everything has time to adjust in temp and residual motion from being moved
Why would you think that if you inflate a balloon with water at a lower pressure, nothing would happen when popped underwater, at a higher pressure?
The hot water one made a heart :)
The fact that you can pop the balloon under the water, means there exists a pressure difference, so the dye will moves outwards after the pop, also, the way the elastic surface of the popped balloon returns to having no tension will create turbulence in the water, not just due to drag, but also whipping.
So some of yall didn't know heat rises? That's what I got from this.
Its for kids now a days kids dont let go of the phone so they are trying to get them to educate through their addiction .
And they are making money through
I think the tension of the balloon made is so that it pushes the water so it causes stirring, if the balloon instantly dissappeared without interrupting the water in and outside of it it might retain it's shape
... although I wonder if the missing space caused from the disappearance of the baloon might also cause some disturbances
(I'm just a random person on the Internet that doesn't have a credible scientific background so please correct me if I'm wrong)
That is a great idea Sonnenblume! I would like to get some slow mo footage to see if the interior water is sort of propelled by the balloon tension because I am curious myself! Thanks for the idea.
The energy in the balloon is released when it pops, and it does not just peel away from its contents so the pop will help mix the liquids.
I noticed there was a lot less difference between all the balloons than I initially expected
Cold sinks, hot rises. Room temp is like hot.
I notice that I used to think that air pressure contributed more to the noise of a balloon popping, but I'm pretty sure it's just the elasticity of the rubber snapping back.
Bro the presenting of educated hypotheses prior to execution of the experiment was awesome. It was the the perfect introduction to the purpose of the video and the overall pursuit of knowledge via the scientific method
Casually making a whole experiment protocol in one short video - first questions and assumptions about the outcome, showing what happends and describing why what should happen/happens and then asking what we saw wow and I enjoyed this silence lessen lol
This makes me think about how heat rises and cool air stays at the bottom
The room temp water would probably hold its shape except you have a concentrated dye that wants to equalise
Tells me a lot about the relative density of dyes tbh lol
👍 Wonderful video art work! An excellent initiative you have taken. Thank you very much.
You are doing great. Keep up
The good work man.
This means pressure corelate with energy (temperature), which means at high energy (hot) the molecule are more spreads and makes the density less, and in cold the molecule more closely so its more dense and its going down,then the next question will how about ice, why its on surface if water or ice on glass floating at relatively top of the glass, and suprise ice less dense than water
The hot water looked like a heart when the dye started to dissipate
Your voice is so calming
the cold one sinks and the hot one gois up
In the room temperature the green stays in the middle, in the cold temperature it goes down and in the hot temperature it goes up.
Your voice is very soothing
I love this channel now
The tension from the rubber Ballon being stretched was the main reason why they mixed rather than them just holding there shape at room temp
Nice.. will you do salt water next? Salt water balloon in fresh water and visa versa.
I noticed that I've been wasting an hour of my day mindlessly scrolling through YT Shorts that I won't remember 10 minutes from now
The hot water diffused the fastest and the cold water diffused the slowest.
I noticed dispersion is normal, but they have preference if other factors are present.
Cold goes down, hot goes up, room temp stays in the middle for a second before going up
The narration is so sweet
What really shocked me was that the results were exactly what I expected.
I NOTICED THAT I WASTED A WHOLE MINUTE OF MY LIFE BY JUST WATCHING WATER BALLONS POP
dude ur voice is so good lol
This is a good example of Henry's Law which states that at a given temperature the solubility of a gas is directly proportional to the pressure it is dissolved ....😊
The water didnt hold its shape because the green dye wanted to defuse evenly through out the water. Elements in a fluid will always move from a high concentration to a low consentration
I have genuinely always wondered about this
Exactly as I expected
at the end you can see how the water with the red dye sits on the top as its own layer, pretty neat
I noticed I spent 60 seconds more than I ever would on water.
The coloring in the water also makes it want to mix because the surrounding water is "pure"
I noticed balloons with colored water popping underwater and I noticed 1 minute of my life I'll never get back.
"I thought the die would hold its shape..." This dude was born yesterday and has never witnessed how diffusion works lol.
Heat rises in general not just water. That's why holding your hand over a fire will warm your hands, but holding your hand under a fire doesn't.
There can't be any tension in the dye container/balloon, for it to hold its shape after you pierce it.
I noticed the dye on your hands at the end
this is another way to show how heat rises and cold sinks
You showed diffusion in your experiment but I noticed concept of pressure in liquids.😂
Reminds me of the experiment we did in class once where we essentially created mini convection currents in a tank of water by placing a heat source below it and dying some of the water so we could see it moving
I think I did something similar in science class when we were learning about convection currents
red balloon is giving me flashbacks to the beginning of every month
I wish UA-cam was around when I used to have to do science fair projects
I'm having ptsd flashbacks of partial differential equations.
if the water has 0 it will be ice 😂
I noticed that I will never get that minute back.
Thats why they put AC on the top of the wall and heater at the bottom. Cuz heat travels up while cold travels down..
It is kind of a mixture of bursting out like air and holding its shape like water. The sudden relief of pressure seems to make the water expand but still kind of hold its shape, but the expansion creates eddy currents that quickly mix it up.
The thing I noticed is that the water looks really dope at the end
Great short FlemDog Science😊
This is very important science. Thankyou
What i noticed was the fact that you didn't address the contents of the balloon being lightly pressurized due to being inside a balloon. If the membrane of the balloon is stretched at all, there's force being exerted on the contents, popping the balloon relieved the pressure. That's why it doesn't just hold it's shape.
Wow he figured out how convection currents work.
Warmer one diffuses faster than others because diffusion is directly proportional to the kinetic energy of particles
I noticed that if you don't want sudden currents from the squeezing of the popping balloon you need to change the methodology to something that is rigid and not compressed.
So basically exactly what was expected lmao
That it kinda obeys normal air temperature rules. Hot air rises like the hot water, and cold air sinks like the cold water
My guess for the room temp sample is that evaporation is cooling the upper water a bit, creating a temperature gradient. The water near the top was cooled by evaporation and sinks, displacing water at the bottom, therefore does not hold the shape of the container for a significant amount of time.
i understand wanting to visualize the thermocline, but i wish the hot water was also shown with a control variable breaker
mostly that what happens to it depends on the temperature and the direction of the popping
this feels like im watching blues clues again
I remember learning in class our teacher asked us why the freezers would be at the upper part of the fridge, hot rises while the cold sinks the blue dye sank while the red dye rise to the top
I noticed i spent my damn 1 whole minute seeing a guy poppin different coloured balloons under water🗿
Bro... i was legit thinking this like a day ago
seriously im ok with my phone being listened to, but when it expands to inner thought it becomes not fine.
