Do Suction Cups Work In a Vacuum Chamber? Will They Stick?

[@prayerpowersr854]

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

[@dalmack2163]

Put a phone with a screen protector that has a lot of air bubbles in the vacuum Chamber

[@nakog8686]

[@justinmartinez325]

yes please

[@justinmartinez325]

yah, put an iPhone with a screen protector with lots of bubbles

[@rick92rr]

That sounds great!!! xD

[@NandanAgarwalnandan3101]

Totally worth a try

[@FunnyPig]

Oddly satisfying when seeing it suck against the chamber😀

[@HappyGamer-br1ls]

FunnyPig omg it’s you

[@jesssald]

Surprise surprise!

[@cuberynth3079]

FunnyPig I subscribed to your channel

[@organicpoppy354]

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.

[@TheActionLab]

+Organic Poppy great! I love hearing that!

[@gretawright3385]

My 7 year old asked me how a suction cup works and this was so informative and fascinating! Thank you so much!

[@chris_1337]

Surprised they were still hanging on like that for so long! Thanks for all the cool experiments!

[@testfire3000]

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. ^_^

[@graw19]

It would be funny if all of them would fell off in the same time XD

[@Stan-rs1ne]

+ Satisfaction 100

[@Recommendedforyouall]

Thank you for the suction cup demonstration, I had no idea how it worked.

[@willgazer]

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.

[@EVPointMaster]

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

[@bendix2648]

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

[@user-kz8vw7ry7o]

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.

[@bendix2648]

Some random person , Uh yea I didn't thik of them

[@RobertMinkler]

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.

[@Ktulu789]

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.

[@amfdoozy]

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.

[@syedwaizuddinsk3852]

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

[@Guiboard]

Well done :-) I like that you keep it simple. I didn't expect that many suction cups, that was a plus, thanks!

[@jerrybobteasdale]

Cool. I was surprised that any stayed stuck during vacuum.

[@NickRoman]

You have some champion suction cups there! You should identify those for when you need some really good suction cups.

[@K775-v5r]

I've actually found many of your videos very interesting! I'm a new watcher here.

[@SupermuzuDK]

I think it sounds like you're talking with the biggest smile on your face 😄

[@KineticKiwi]

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.

[@TheRickkyle]

i hope someone make a video bout that

[@marko_z_bogdanca]

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.

[@juluke8385]

@@marko_z_bogdanca But... That's lie the whole point of them

[@Brandonvscars695]

put a human poo in the vacuum chamber. sorry to sound childish but I'm genuinely curious to how it would react 😂

[@TonyTear]

if there is air in the poo it would expand if not it wouldn't do anything

[@yousefyasin8014]

Hey..this is a pretty good quality test for the suction cups...

[@OhhWellShanel]

i was sorta hoping they'd all pop off simultaneously lol but it was still cool to watch either way

[@infinitygmrhd1660]

what if you put helium ballon in there will it fly ??????

[@ayzix-polytopia3854]

INFINITY GΛMΞR HD It would expend and take all the space in the vacuum chamber,

[@Difixed]

INFINITY GΛMΞR HD A ballon is not filled with helium. I don't even know what that is.

[@ayzix-polytopia3854]

INFINITY GΛMΞR HD no it's not going to explode. I already saw a vid on it, it didn't explode. It just expanded.

[@scrub3649]

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.

[@msbjr23]

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

[@gregsnow1696]

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?

[@TheActionLab]

+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.

[@Ktulu789]

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.

[@themonkhinekie3243]

I wanna see too how the vacuum suction cups stronger to regular ones...

[@danielcastrillon7643]

I really like this kind of experiments. :D

[@samiral5806]

+Samira L yep I am!

[@thoseweretheavocados]

ohhhh! who is Davey? :o

[@rickyhall7514]

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.

[@rieviousretrograde4281]

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.

[@Terminalss]

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

[@MrG-ff1bv]

I have the same suction cups (But the big ones) and cool vid.

[@AttilaAsztalos]

[@sanjeen2503]

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)

[@dancho2363]

Plot twist they spontaneously combust

[@FuddahMukkah]

You should test the difference between certain suction cups and their max weight capacity vs 2x atmospheres

[@frodosadventures8757]

Wow! The answer to a lifelong question, I've wondered about this every day. Just kidding! Pretty cool!

[@natty1]

When that last one fell my heart cracked a little

[@unicusDOTcom]

Good experiment I expected them to stay on as the suction would hold them in place.

[@TheActionLab]

+unicusDOTcom yes this helps us understand that there is no suction without an atmosphere!

[@darken3150]

Bro I don't think you understand what is holding them on. Think about the air that around you as an ocean of water, as you go below the water the pressure increases. The same is true with our atmosphere of gases (that is miles deep) which create pressure on us. In this experiment as you push a suction cup to the acrylic and push all the air out that ocean of atmosphere above us is pushing that suction cup to the acrylic. This is demonstrated by the vacuum chamber, as he removes this force of pressure the suction cups are no different that putting a piece of paper against the acrylic and expecting it to hold. Hope I said this right and it makes sense, i'm just trying to relay it as how i understand it.

[@junbh2]

The suction is kind of like a mini-vacuum between the wall and the suction cup, though. Once you turn on the vacuum, the 'suction' on the other side is even stronger. (Which is the same thing really as saying the air stops pushing it, but a different way of looking at it).

[@mrrutledge1967]

Hydraulic Press Action I agree that of you tried sticking vacuum cups with no atmosphere they wouldn't stick but you're selling the idea that atmospheric pressure keeps them pushed to the glass Which is nonsense. You're using cheap vacuum cups and the ones with most of the air pushed out stuck longer for obvious reasons to anyone capable of critical thinking.

[@darken3150]

Atmospheric pressure does keep them pushed to the glass...

[@PhatPat0420]

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.

[@nowonmetube]

The One-Eyed King he made a video about that already

[@ThyAnarchist87]

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.

[@dansanger5340]

Probably the least surprising thing I've seen on this channel.

[@Oltux]

Hi, i told a KZbinr (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.

[@Marv3Lthe1]

Put Bubble wrap inside it.

[@imtones9152]

I don't know why I give a shit, but I still watched this lmao

[@livingroomradio8372]

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.

[@Mikeological]

Put underwater matches in the chamber. Like the ones that still burn when you dunk 'em.

[@seanberger9461]

Wow! It's almost like Cody's Lab did this a few weeks ago.

[@anthonyfernandez1768]

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

[@VyzerMusic]

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

[@jakejones5736]

Just curious what your gage would read if you did your vacuum tests at high altitude, say 10,000'.

[@abhishekgourav6144]

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..

[@ptrk47]

Two active walkie talkies facing each other in a vacuum chamber would be cool

[@TooTsaka]

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.

[@TnC4G]

Could you once put ICE in your Vacuum Chamber? I just have been curious what will happen to ICE in a Vacuum, since water gets boiling under a Vacuum. So could you please do this experiment. You would make me really happy :)

[@akwanet]

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

[@doesfireburn8532]

these are the types of videos where you just think to your self : ah ok so guess thats a thing

[@muttandme2901]

kool experiment 😎

[@bdilly17]

I have another theory, but not sure if it's true. So I imagine that not all of the air is pushed out when the suction cups were pressed against the wall of the chamber. If there was some air still trapped, is it possible that as the pressure decreased the volume of the trapped air expanded causing a decreased amount of suction until they fell off? Or that the trapped air expanded so much that it escaped and broke the seals of the cups?

[@jonr3198]

The amount of air pushed out is going to depend on how strongly you push on the suction cup. Once the pressure outside the cup is unable to keep it against the wall, it falls off. Saying that the trapped air was expanding is just another way of saying that the inside cup pressure is higher than the outside cup pressure; either way it means there's no more net force pushing it against the wall. It's possible the few that didn't fall off had a higher vacuum than what the machine was capable of producing, I'd find that more likely than purely plastic-plastic interactions...

[@tom_something]

I wonder what causes the adhesion between the rubber and the plastic. I had assumed the "stickiness" was a suction-cup effect on a microscopic scale. In which case the "adhesion" is really just the atmosphere holding them together. But seeing how well some of these held up under a vacuum certainly makes me question that assumption.

[@gamesmiths7137]

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

[@Commando303X]

I'm surprised the larger ones do not seem to be falling off first.

[@vangildermichael1767]

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.

[@demotics2005]

Im curious to see what would happen if someone tries to stick them when it is already in a vacuum from the start. I know it's difficult to do it or maybe impossible, but in case it is doable, i really wish to see it

[@PapaOhome]

they dropped like flies, as they say, this was exciting to watch, this might prepare us for the future when vehicles with varying amounts of amospheric preassures, may be harder to climb rocks with rubber tires, they will need these types of exploration before they can make predictions about motoring around Mars or the Moon, or shoes with suction cups on them.

[@TheActionLab]

+Papa O yeah you're right!

[@Mizt_Plays]

*reads title* Well this is gonna be a quick video

[@hightiernub1313]

The suction cups by default won't work under a vacuum. Suction cups work by having a lower pressure within the cup as the pressure outside is greater. This causes the cup to stick to the all as the outside pressure that's greater will press in on the inside of the cup with friction holding it. By having them in a vacuum the difference of pressure is gone and the suction cups won't stick.

[@michaelbedford2993]

I think the pressure is arbitrary. A properly engineered suction cup would stay on due to tension preventing entropy, more so than a counter pressure holding it on. Tension vs pressure, consider entropy

[@hudsonball4702]

Try a block of swiss cheese next!

[@xgamers4516]

put some gummy bears in it PLZ

[@bloodheart2483]

Put those suction cut while at full vaccum to see if they are more hard or easyer to pull out

[@MaltaMcMurchy]

Hello, I enjoyed this video. I'd like to see what happens if you place in egg inside of a vacuum chamber. Thanks.

[@vrj93]

nice choice

[@jonathanb6371]

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!

[@jjmoore7756]

put an ink cartridge in the vacuum chamber

[@TheCls63]

your channel should be call ''Will it Vacuum?''

[@manojvarmaalluri]

please try petrol/gasoline in vaccum chamber. it will be very interesting because if we increase pressure inside it will cause the material inside to boil but at the same time petrol need oxygen/air to burn

[@Cube8]

All right, waiting for bets. Which one(s) will stay on?

[@DANGJOS]

Some of the suction cups may even have been pushed of slightly if the pressure inside the chamber ever dropped below the pressure in the suction cups

[@DANGJOS]

+Shaun S. 8bit Not if there was significant Van der Waals attraction between the plastic and acrylic chamber, which he thinks is there anyway. Perhaps they had to be pried off from the internal pressure

[@davidlemaire7032]

Wow! Very interesting! Gteat video👍

[@just_thibeau6682]

What will happen if you let a small computer run in your vacuum? Nice vide

[@leedchristensen]

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..

[@Iliketobrap]

Lol I love how enthusiastic the comments are about suction cups in the context of science 🤣🤣

[@juluke8385]

[@msbjr23]

Can you do a fidget spinner in a vacuum chamber? Compare the times of one in a chamber and one that is not. I'd like to see how much of a difference between the times there would be.

[@mickeltrix]

^^

[@FiltiarneElite]

How would he get it to start spinning under vacuum?

[@infectedruby]

m b I

[@msbjr23]

Even cheap spinners can spin for 1:30, so you would set it down in the vacuum, give it a good spin, start the vacuum, wait for results.

[@The_Wosh]

it would spin more because of the lack of friction and air resistance

[@anthonyfernandez1768]

I have always been curious about why the LEM (Apollo Lunar Excursion Module) which according to NASA had only a kind of metal foil (Mylar?) for walls, would not have gotten a "blowout" in the vacuum of space. There's presumably 14.7 lbs psi of pressure inside of it and a vacuum ouside (the Astronauts -Armstrong & Aldrin) were not wearing space suits inside there

[@kez963]

Will they stick to the wall if you shoot the toygun with those suction cup shels in the vacuum?

[@ChallengeTheNarrative]

Maybe a little electrostatic attraction between the two plastics

[@Calzonuda]

lmao the ad was better than the vid

[@SEThatered]

I always get peeved when these suction cups don't extend the hook beyond and below the suction cup edge to have a resting point around which the load torque can pivot and only apply almost-linear pulling force on the suction cup, preventing an uneven deformation of the rubber/silicone. I guess not every designer/manufacturer is an engineer...

[@adelbudeiri9547]

Fidget spinners in a vacuum

[@somedude3072]

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?

[@Andrewlohbihler]

I suppose the same logic applies to plastic wrap and sticky note pad paper. Try weighting low stick notes and put them under a high vacuum. Will they fall off? My guess is that they will still stick but is there an air pressure component to their adhesion to a plastic wall?

[@UnbelievablyGauche]

can you have a glove built in to the lid, and once there's no air, show us you trying to stick em to the wall??

[@timscoviac]

According to your video with the cup gaining water on the inside due to the matches burning all the air up, these aren’t actually suction cups? Nothing is being sucked rather then pushed. So they are push cups

[@peterwestsearth3640]
