Opening a Vacuum Chamber Under Water

Now we need water open in a vacuum. Hopefully nothing would break

The fact James didn't complain about how heavy the cube of water was the most amazing feat.

This is basically the Vac-and-fill process for a vehicle coolant system but expressed with a clear box.
I love it.

This is a pretty good demonstration of differential pressure at action, this could also be used to show the dangers of it in a controlled environment.

That’s how we fill cooling systems on cars as it makes the bleeding much easier if required at all. Great way of doing the job on rear or mid engine cars as the rads are all the way at the front.

Actually I'd say you had less air than the resulting bubble has. The incoming water has some air dissolved in it but since inside the chamber the air pressure is very low some of the air in the incoming water escapes to fill the available space.

"without letting anything come out" - that implies, that there is something inside, that WANTS to come out. But there simply is nothing. Nothing wants out, but the entire space is literally empty and the pressure of atmosphere and water pushes the water in with force.
I guess many of you knew by yourself. It's still fascinating though. I assumed, an empty vacuum chamber wouldn't float, but it made me think and realize, it's not the air, that let's things float, but the amount of water that gets displaced, and it doesn't matter, what displaced the water, even if there is literally nothing. Learned something new myself!

Wouldn't there be something related to significant difference in pressure in the water than from the box, mostly causing the water to instantly shoot in?

I would have loved to see you only filling a small part of the vacuum with water. The low presure in the Camber would have pulled the boiling point of the water to about room temperature. So you could boil water at 20°c.

That’s crazy, I thought it would shoot out a giant burst of bubble air.

I thought he was going to take the entire top off somehow. Also, it's impressive he was able to lift that out of the tub. That would weigh a decent amount (it's literally filled with water), it's at an awkward angle, and it would be slippery so gripping it would be difficult.

I have a question. If you had a vacuum chamber, and had your hand in it while the air got sucked out, would absolutely nothing feel different then air? If that's the case, we can feel air, and air feels like something

Would have been more interesting if you had it on its side when you opened the valve... would it fill the whole chamber or just to above the tap?

This showed me what being “sucked into the vacuum of space” might actually look like. I’ve only seen over the top movie versions

1. I'd like to see displacement before/during/after
2. Can we easily measure the air in that? Is it or can it be used as a way to measure how close it got to "perfect empty vacuum"? Or is a displacement to total volume ratio the easier measurement?

This is the same concept as the vacuum tools you use to fill the coolant system on a car when you do a coolant change. When you refill the system after you pull a vacuum on it, there are almost no air voids when you are done.

Cool! Most blood draws are done with vacutainers, plastic tubes under partial vacuum, similar process and if you have a nice vein a very similar jet of blood comes out just like the valve in your video! Vacuums tech is all around us!

The internet is this endless series of answers to 8th grade science questions, and it's awesome.

A water balloon in vacuum would be fun to see. You'd get opposing forces from the balloon stretching and the vapor pressure, depending on the temperature.

I really, really wanna know what happens if you put a living plant in a vacuum chamber. What would happen if you just took a flower in a pot, jumped in a rocket, got to the moon and left that plant outside the rocket? (I'm guessing the vacuum chamber would mimic that effect 🤔)

Man! You are the totem of luck on how I can finally fill up my aquarium real quik

That vacuum chamber has gone through a lot, good to see it getting a fresh bath

This would've been more interesting if the valve was opened upsidedown underwater to observe the water filling underneath with gravity pushing downward. Please conduct another test if you can like this 🙏🏾

Question… if it were filled only 3/4 with water, would the remaining 1/4 still be considered an “air bubble”? 🤔

How'd I know it would be you? Every time I see someone doing something I have always wanted to see, it's you.

Wait. So a vacum chamber still floats. I thought it was the air making it float. Interesting!

As a mechanic I use this all the time. In modern vehicles you can't just pour coolant in a empty system it won't fill all the way up. It's going to create airpockets throughout the system. So you have to manually bleed the system which requires lifting the front up running the engine so it gets hot and all the thermostats open and put the heater on full blast and feed coolant slowly in to the system. It can take up to 40 minutes to a hour to do this. Instead you would use a valve like the one on the box to create vacuum in the coolant system and then submerge the other valve in coolant and you'll fill the system instantly. No airpockets no bleeding nothing just trun the key and go.

If you had an unbreakable box full of water and froze it, what would happen? Would the massive force and pressure keep the water from freezing? Or would the pressure cause the water to do or even turn into something else?

What were the bubbles made of, in the turbulent water stream, jetting into the evacuated chamber? There was no air for the water stream to stir into the water volume, so what was it?

We use the same process as a mechanic to Fill up coolent system . There is a tool called a coolent airlift. It makes the process a lot easier and you don't have to bleed out air pockets in the cooling system.

I love it.

The remaining air was really cool to see to visualize how much was left

I don't totally agree with your final statement about the air pocket or I just have a thought about it. How much of that pocket is left over air and how much of it has been separated out from the action of "in rushing"? Would have been kinda neat to have an oxygen counter in there as it happened.

You could see the air bubbling in as it was lifted from the water. I hypothesize that there was actually less air left in there after vacuum was applied, and the bubble in there isn't from remaining air.

Now I wanna see what happens when you open it like that, or try and vacuum seal it with water in it.

Genuinely curious because I've never thought this through, but why did it float so well if almost all the air was out? I'd just assume a vacuum would sink.

This Depends on the size and weight of the wall. A 1 metre vacuum chamber with 1mm thick steel walls (probably not strong enough but bear with me) - yes. It would displace 1000kg of water but weight only around 7kg, so it would float.
A 1 metre vacuum chamber surrounded with 1m thick steel walls - no. It would also displace 1000kg of water but weight around 190,000kg, so it would sink.

I love these videos! Especially the little grunt he let out when he lifted the vacuum chamber full of water🙃. Me thinks a vacuum chamber filled with water weighs more than an “empty” one. #SCEINCE!

If there's so little amount of air in it, does that make it float more than it would if air was in it?

When it is partially full of water, you have a “mostly” pure saturated mixture of liquid and gaseous water. In a saturated state, the temperature and pressure of the system are coupled. The pressure cannot increase if the temperature of the system doesn’t change.

Man.. I haven’t had my chamber VACUUMED in a LOOOONG time

I always wondered if vacuum filled balloon would float or sink, was pretty sore a vacuum would float but wasn't sure lol

A lot of that air in that bubble wasn't what was left. As the air was, well, vacuumed in, the low pressure had the water de-gas and even boil. Both lowering the dissolved gas in the water and increasing the amount of non-h2o gas in the chamber

That was awesome but can you do it again but only let in a little bit of water and then close the valve then watch it vacuum boil?

Man! You are the totem of luck on how I can finally fill up my aquarium real quik

Action lab is the best. I wonder if he can make a vacuum chamber big enough to drain the swamp...
Let's go Brandon!

Is there any chance that the "air left" inside is pure gas ( oxygen and so on) from the water itself? As if the sheer pressure of water forcing through separated to some degree? Just a thought.

it took me more time than I'm comfortable admitting to remember why the vacuum chamber was floating...

For some odd reason i used to think about this often and could never wrap my mind around it, i would always think where would the space go lol

No, those air bubbles can be seen going in as you're taking it out of the water. You pulled the tank before the pressure equalized.

I seem to recall a physic question, asking what would happen if you put a box, containing a vacuum in water, would it float or sink?
Now we know. 🙃

So I've been lied too every time I hear that something is completely vacuumed in that box 🤯

*We need vacuum chamber inside vacuum chamber*

The water isn't even that deep and it goes in so fast!
Just imagine you breathing below 1000 feet underwater
Edit: We are like vacuum because we inhale and inhaling is pulling air

Can't wait for "What happens when you put a thermonuclear device in a perfect vacuum"

It's interesting that it still float without much air in it

I love how you could see the small vacuum bubbles while the water was entering, that stuffs wild

The byford deep diving thing makes so much more sense to me now

Where do the air bubbles, while filling the volume inside the box come from?

0:52 - Or that was the dissolved oxygen in the water that turned back into gas/air when it got purged into the vacuum chamber (note the bubbles when water was gushing into it).

Did you calculate the volume of that box before hand to make sure you got an accurate amount of water for the experiment

I always thought I was weird because I did weird stuffs sometimes. It appears that my spirit animal is probably a scientist after all.

Not complete until he says "That's so cool!"

And here you see one of the most complicated ways to fill a box with water.
Jokes aside it is pretty interesting.

Thank you! My question about how much air keeps actually remain inside the chamber, was answered! ❤️😘

You know. I kinda expected it to sink. But it makes sense why it didn't.

Take 500ml water in a 1l jar.
Apply pressure on the open part of the jar
That is from its mouth by pushing a flat surface
That has the same size as of the jar's mouth ( just a bit less so that it can go inside like a lid)
And the more you press the more pressure that builds up inside the jar.
So the time when the lid cannot be pushed any further
That is the volume of the water and air ( air which was already present in the jar) combined stops it.
Then if you tilt that jar upside down
Will the water fall / move ?

Is it weird I imagined being trapped in there in a large scale version and having to escape before drowning?

The air at the end, probably, was just what air was naturally in the water anyway.
Nice vid.

Wow I mean wow that was soo amazing to watch...words can't describe my amazement.

I understand the physics behind this… but I was still waiting for an explosion 😂🥲

Wait so if you open an empty container under water it gets filled with water? No way!

It's like there was no air in it! Wow!

Can you make water from hydrogen in a vacuum chamber? You know, since it's Hydrogen squared Oxygen 0? Now I'm not a chemist but is that possible?

Did it weigh the same as the pressure it took to hold it down 😆

There's also a vacuum effect ( idk what it's called) that can rip you in half just by the sucking power it has

my question is, if all the air was removed why does the box still float!?

That poor vacuum chamber has been through so much 🤣

Could the “air” bubble at the top at the end be water vapor? (Or maybe air that was dissolved in the water…?) I doubt the amount left in the chamber would be quite that much…

I'm surprised that holds nearly a complete vacuum

Is anyone else surprised it takes so much weight to submerge the box? I would have thought a near vacuum wouldn't have enough gas to make it float

So if you could discharge the water from the vacuum chamber (into a pipe) as it filling from the top would this be considered or could be used as a pump? If yes how long would it run for considering the vacuum chamber stayed submerged?

This guy does more with a single vacuum chamber than MacGyver ever could with a paper clip and duct tape

I fear that one of these days, something's gonna give and mess up that handsome mug of yours!

I appreciate that you always wearing safety glasses!

now... if you had the vessel containing the water to be air tight and strong so that it wouldn't compress AND you open the vacuum chamber in side the water.. it will boil in the chamber to fill the space... it would be cool to see exactly what would happen.. maybe the VC gets filled with steam or the water level lowers and the steam is at the top of the water chamber...

If I'd done this it would have exploded in my face when I lifted it out, even if that's not physically possible.

This guy is that one science teacher everyone has...who's never interested in ANYTHING thats actually exciting in science🤣✌️

Thought he was gonna slow mo opening up a panel… a little dissatisfied… 😂

⚠️I HAVE A SERIOUS QUESTION⚠️
If you were stuck in a vacuum chamber and all of the air was sucked out instantly, could you still inhale, even if it’s not oxygen? Would the air get sucked out of you/your lungs?
Thank you for your time.

When he pulls the vacuum chamber out you can see some air leak into it; so I’d say like half that air in there is from the vacuum not able to pull it out, and then the other half is from when more air leaked into it

So what happened to the “extra” air if it didn’t escape to the surface? If it was dissolved into the water, would it give the water extra oxygen molecules? And if it added a molecules to the formula, wouldn’t it be a different chemical?

it’s not completely evacuated if there’s air left in it, yeah? 😆

can you fill it completely with water and vacuum all of the water out instead for a more complete vaccum?

I always expext his experiments to be far more dangerous than they actually lol
