- In this video I show what happens to suction cups when you put them in a vacuum. I get an assortment of suction cups and stick them to the walls of the vacuum chamber. I talk about how suction cups work by removing the air from the inside of the cup and creating a pressure differential that causes the atmosphere to push the suction cup against the wall.

hi there my name's john recently my son has been watching your videos and has suddenly gained an Interest in science and technology which was a great change from all the video games he usually plays so thank you for these videos
+John Kyon hey perfect, that is exactly why I do these:)
holy shit lmao
Orange Flavored Clorox Bleach hahahahahahaha
What the fuck dad?!?!
John Kyon that didnt even make any sence but ok,"parent"
Put a phone with a screen protector that has a lot of air bubbles in the vacuum Chamber
Dalmack fart This is a good idea.
yes please
yah, put an iPhone with a screen protector with lots of bubbles
That sounds great!!! xD
Totally worth a try
I really enjoy these videos and I appreciate when you show us the meter, or at least tell us the pressure as it counts down.
Very cool! Thanks for sharing. ^_^
Surprised they were still hanging on like that for so long! Thanks for all the cool experiments!
Oddly satisfying when seeing it suck against the chamber😀
FunnyPig omg it’s you
Surprise surprise!
FunnyPig I subscribed to your channel
Well done :-) I like that you keep it simple. I didn't expect that many suction cups, that was a plus, thanks!
My 7 year old asked me how a suction cup works and this was so informative and fascinating! Thank you so much!
i specifically wanted to watch you do this and you had the video. you're amazing
Thank you for the suction cup demonstration, I had no idea how it worked.
That was Awesome Dude! I enjoy about All of your experiments, but this one was really cool to me. Thank you!
Good thing that you kept the pressure gauge within the video frame.
Continue this in your future videos.
And thank you for making all those wonderful vidoes
All your videos are really interesting. I want to thank you for making them, I really learn a lot.
I like the way you are doing these videos, you are very precise and check every combination :)
I've actually found many of your videos very interesting! I'm a new watcher here.
Good experiment I was thinking about this for long.
I am the first grade teacher that mentioned how we watch your videos in class. Last Friday I had someone bring a vacuum chamber into my classroom. The kids were thrilled! They had so many suggestions for what we should put in the chamber. Thank you for providing a kid safe channel! You are inspiring little scientists.
+Organic Poppy great! I love hearing that!
It would be funny if all of them would fell off in the same time XD
+ Satisfaction 100
While there is a vacuum, stick a suction cup to the bottom of the chamber and put the air back in. Now try to pull it off
Aelerity Maybe a small remote controlled robot arm that cant press the cup against the bottom lf the chamber. The question is, if the remote controlled robot is still working in a vacuum
Some vacuum chambers have sleeve-like gloves in the wall of the chamber to manipulate things in it. These gloves are usually only in professional ones.
Some random person , Uh yea I didn't thik of them
EVPointMaster this and compare the one placed under vacuum to one placed in normal atmosphere. There's got to be a way. Maybe weight on the suction cup to press it down? A brick could work.
Maybe just leave them on the bottom and remove the air. Probably when the pressure is restored, some will just auto stick. If they are flush with the floor, it's highly possible that air gets fastest into the chamber than below the cups, pressing them down.
I really like this kind of experiments. :D
Cool. I was surprised that any stayed stuck during vacuum.
You need a digital altimeter on your vacuum chamber. It would be neat to know at what altitude the reactions of your experiments take place.
put a human poo in the vacuum chamber. sorry to sound childish but I'm genuinely curious to how it would react 😂
if there is air in the poo it would expand if not it wouldn't do anything
SummerCorn LOL
SummerCorn Very good question! And will the steam be safe to condense and drink?
Brandon P it would get flagged and that would be pretty disgusting
Brandon P hahaha
i cant believe i actually started rooting for the suction caps to prove him wrong lmao
Hey..this is a pretty good quality test for the suction cups...
I have the same suction cups
(But the big ones) and cool vid.
Hello, this inspired me to get out of my house and actually learn something about the atmosphere. Today I went to Mount Everest and discovered that's top of the mountain is actually in the last layer of the atmosphere. The troposphere.
You have some champion suction cups there! You should identify those for when you need some really good suction cups.
kool experiment 😎
i was sorta hoping they'd all pop off simultaneously lol but it was still cool to watch either way
Just curious what your gage would read if you did your vacuum tests at high altitude, say 10,000'.
It would have been much more interesting to see if suction cups would still stick if you were to try to apply them on the surface while the chamber was in vacuum. It would have been much harder to accomplish though.
i hope someone make a video bout that
Of course they would stick. This experiment has a flaw. The reason why his cups are falling off is that there is some air left under the cups and it expands under the vacuum.
@@marko_z_bogdanca But... That's lie the whole point of them
The things you never knew you never knew until this channel teaches you.
Wow! The answer to a lifelong question, I've wondered about this every day. Just kidding! Pretty cool!
Wow! Very interesting! Gteat video👍
Nice!
I don't know how I got on your channel but when I started hearing your voice it immediately reminded me of Davey and when I saw you at the end I was sure you'd have to be his brother :D
+Samira L yep I am!
ohhhh! who is Davey? :o
What's interesting about this is the fact that you are removing the air from the vacuum chamber you are essentially making the lid become a giant suction cup
what if you put helium ballon in there will it fly ??????
INFINITY GΛMΞR HD It would expend and take all the space in the vacuum chamber,
INFINITY GΛMΞR HD
A ballon is not filled with helium. I don't even know what that is.
INFINITY GΛMΞR HD no it's not going to explode. I already saw a vid on it, it didn't explode. It just expanded.
It all depends on how much material makes up the balloon itself. A small balloon would pop where one that can stretch bigger then the chamber itself would not.
The answer is no it would pop and then the latex or plastic or whatever its made of would fall to the bottom of the vacuum chamber
This was cool
nice choice
I think it sounds like you're talking with the biggest smile on your face 😄
Note to self: if you want to really piss off an Octopus, put it in a vacuum chamber...
Attila Asztalos ROFL good one!
You should try the suction cups for gps mounts and also car body repair. It would be interesting to see if the mechanical lever which pulls the center of the cups out to create suction helps or hinders it in a vacuum. I would guess they could stay stuck even with weight added at your lowest pressure.
Before video comment: The cups will fall off because, suction cups work by making a vacuum of their own to make them stay on a smooth/ flexible surface. So they wont work if the suction inside the cup is matching/ greater than the surrounding air pressure.
After video comment: 1:58 called it. Also to see them resuction onto the glass was interesting. I wonder how much force it would take to pull that off without using the vacuum chamber again.
Hi Action Lab,
I would like to know if it is possible to make vacuum bubbles in a container of water(or any liquid preferably one that does not evaporate) inside a vacuum chamber? For example in normal atmosphere if you were to plunge a clear cup facing upside down into a container of water, you could see air in the cup. The air basically displaces the water preventing it from entering the cup. I would like to know if this still works under a vacuum? What would happen if you plunge a cup upside down filled with nothing but vacuumed space into a liquid? Hope my question is not too complicated or wordy. Thanks for your videos!
these are the types of videos where you just think to your self :
ah ok so guess thats a thing
Interesting.
Where di you get your vacuum chamber? All the ones I've found seem awfully expensive for an acrylic box.
Wow! It's almost like Cody's Lab did this a few weeks ago.
Two active walkie talkies facing each other in a vacuum chamber would be cool
I'm curious to see what Oobleck will do in the vacuum chamber. When the air rushes back in and it should shrink back quick, will it act like water or will it become hard as the air removed.
The One-Eyed King he made a video about that already
*reads title*
Well this is gonna be a quick video
Plot twist they spontaneously combust
Put Bubble wrap inside it.
I would like to know if you could re apply the cups once they have fallen off. You may not be able to in a complete vacuum but with just a little air remaining it might be possible. Then allow the air back in and see if the cups are extra hard to remove. Because I doubt the typical action of pushing on a suction cup removes all the air so one placed in a vacuum should be stronger once the vacuum is released.
If you put them facing the bottom then suck the air out would they suck down to the bottom or do they have to be sucked in first?
When that last one fell my heart cracked a little
Does it take more force to take a suction cup off a surface outside vs inside ?
Hello, I enjoyed this video. I'd like to see what happens if you place in egg inside of a vacuum chamber. Thanks.
Better yet, how about testing whether a suction cup can be applied in a vacuum. Since it works on pressure differential, can you create a difference in pressure in a vacuum?
+Greg Snow maximum pressure you could get is about 0.1 psi since that is about how low my chamber gets. Might not be enough to hold it on, but maybe it can! It would be hard to apply in the chamber though.
The Action Lab you could have checked if the last surviving suction cups had visible differences against the ones that fell first. Maybe they were better made, smoother, more round, more plain or taller, or cleaner or greasy or something that made them better.
That info would be great to know! :D
Even better, number a bunch of them and take notes of the pressure at which they fell, then you can gradually look at each one and tell why some are worst and some are the last survivors.
Preferably, use brand new cups from a bag, and wear gloves while numbering and sticking each.
I wanna see too how the vacuum suction cups stronger to regular ones...
Would the same thing happen if you put them on after making the vacuum because if you put them on before there could still be some air underneath them right?
Interesting ...
Hey, I have an experiment suggestion! Could you build a Crookes radiometer out of the vacuum chamber and some black/white vanes. And try to make the vanes rotate by photon pressure (which is not achieved in the actual radiometer - that one works on heated air currents in partial vacuum)
Nice vid
I don't know why I give a shit, but I still watched this lmao
You should test the difference between certain suction cups and their max weight capacity vs 2x atmospheres
The least few who didn't come off are like students in the class who don't stop, no matter what to write in an exam, until the time's up of course...LOL
Это очень круто! спасибо)
Enjoyed the freakshow! 😂
This would be a good way to host a betting game, just place your bet on the one that you think will last the longest xD
Probably the least surprising thing I've seen on this channel.
You need to try peeps!
Hi, i told a CZcamsr (Nozman french) to do that a few years but he wasn't interested. Nice to see that it work.
Now can you try to stick suction cups when the vacum has no air (with your magnet or special gloves) and turn to normal pressure and try if suction cup can carry more weight ?
And then another experience : Champagne in high pressure vacuum chamber (more atmosphere) to see if bubbles stop. Because i think it's the same effect has boiling water : It's not really boiling.
There is a lot of things i would try but i havn't this chamber. I need to buy one.
part 2 of my question because part 1 got sent before I wanted it to: Could you perform an experiment by constructing a sealed box with a form covered with different types of foil and put them into your vac chamber to see if they would maintain their sealed integrity or if they would fail (get a blowout) I saw the "chip bags" which brought this to my mind. Thanks, Anthony
May I use this video in another video, I will keep the link in it, thanks
what would happen if you had one vacuum enclosing a second vacuum? is that possible
lmao the ad was better than the vid
Can you figure out a way to stick them back on while inside the vacuum? Kind of a vacuum within a vacuum, not sure if it will work at all since there is no air to create the differential pressure..
Those last few that would not fall. I think that was from the "van der waals" forces. The static electricity making a kind of a magnet.
is it possible to do the drinking straw effect on a bigger scale?
like when youre drinking and rapidly you cover the hole with youre tongue or your finger and the water doesnt fall
Is there a way in which you could make (near) vacuum or very low presure and then place the suction cups?
Then, if you returned to normal presure, will the suction cups stick/suck stronger?
Sorry if I had terrible English, not my first language :P
Is rubber suction works also with plastic container?
i got an idea from falling forks..can u do some sound test in vacuum..like put some BT speaker in it and play it!
you should put some kind of pressurized container with a manometerin it to see if it show higher pressure than it really is in that container
Hope this question on how they work came into other people’s mind too not just mine randomly 😂
Put underwater matches in the chamber. Like the ones that still burn when you dunk 'em.
so what about if you lick them or make them wet will they then stick better in the chamber?
Only subscribed to for a year now, love your videos, but have you or can do one with a helium balloon in a vacuum chamber
Makes sense what's going on. After all, you're creating a vacuum within the suction cup, and since the material has such a good suction due to it's gel-like quality, no air can creep in and knock it off. When in a vacuum, what little air is trapped inside expands as it's getting drawn out by the vacuum outside the suction cup. Therefore, they start to lose their grip which is why you see an expanding circle of air in the suction cup.
Ultimately, it shows how much force you have to pull with to take off the suction cup without having to resort to peeling it off. You're fighting against a mini vacuum.
wow this was a very smart and important question which bugged the entire humanity leading to WW1 and WW2 just to find this answer...your video saved the world from WW3 to ever occur over this...
Joking re...chill..
Correct me if im wrong, but if you press the suction cups while in the vacuum environment, it would stick just fine isnt it?
can you make a video in which you compare the travel of sound waves in a vacuum chamber and in a high pressure chamber? use a Dezibel o Meter or how ever these are called in english
what effect does gravitation in vacuum chamber do?. I mean when you put feather and something heavier will it falls at the same time because there is no air resistance? (sorry for bad english)
Yes it will and he already did a video on that
you should do an unopened bag of chips. both in the vacuum chamber and pressure chamber.
try setting up a thing that sticks a suction cup onto the wall while it is under vaccum, would it be impossible to get off under normal atmosphere?
So is it Van Der Waal attractions that kept some of them sticking to the glass?
When you reach your max vac, what would happen if you reset the suction while still under a vacuum condition?
put some gummy bears in it PLZ
put extra hot molten glass in the vacuum chamber. its supposed to froth up as the gases escape. might be cool looking when it solidifies.
do levitron rotate forever in vacuum?
