They wont stay vacuum sealed because some of them will off gas, then rot in their own gases. This is why they freeze dry and dehydrate foods for long term storage. Removing most or all of the moisture is key. Then vacuum seal it with some o2/moisture absorbing packs and some stuff can last 20-30 years.
Thank you for saying it! I couldn't believe I had to scroll down so far to see someone pointing this out. Within 5 minutes, the bread and apple would have had no vacuum left. Should have put pressure sensors on the jars
Suge212 Exactly what I was thinking!
Silica packs
Someone went to science class
I appreciate your knowledge
Isn't this the purpose of vacuum sealing?
Taikamuna lmao fr😆😂
Yes it is! xD
Same question lol
Oh yeh!
This guy just put a vacuum air lock on a jar specifically designed to already do that
From now on I'll vacuum seal my memes so they don't get stale. Thanks!
This comment is so underrated i swear.
Seems that they're already stale
David Blandini congratulations... you have used 100% of your brain
So Bland.... :P LOL
Looks like they already are.. just get off the internet kid
I don't think you needed to drill the lids - you could just have left them half unscrewed - same as for when they are used for canning - gas can escape by lifting the lid a little, but when the pressure outside the jar is greater, the lid is pressed into place and seals tight
way tougher to reopen the jar when its time to reopen.
@@212go Nah. Just use a bottle opener.
@@212go no just use an old school can opener to puncture the lid
Hey, did not expect to see u here
Note: As someone with over 15 years lyophilization experience, the main issue is that you still have residual moisture and oxygen in the foods themselves. You would need to actually freeze-dry the foods to prevent spoilage. While making freeze-dried pharmaceuticals, you generally have to reduce the moisture content of the freeze dried solids to under 0.1% to prevent mold and bacteria from growing.
Exactly...100%, but if you were going to do something like this, you'll need to ensure all your jars are sterile, re-vacuum most items after its initial with a lot of moister (sp) after sitting for 30mins to an hour and also adding a salt pack.
Dude it's an experiment
or pump chlorine gas into the jar and i bet it would stay fresh
Is there a device that can maintain a constant vacuum? I’m sure NASA has something like that but on a lesser scale, put the items in a item like that and check a month later.
Or use sugar/salt to absorb the water
did he pick up the chips with the same gloves after touching the molded bread?
Different hands
No
Liftsky I cant believe i fell for that twice
ricex2
I was asking myself the same thing, that’s actually gross🤢🤭
@Liftsky I clicked "Read More" expecting for an explanation lmao idk.
yo you just touched moldy bread then ate chips with the same hand, be careful lol
LOL I came to the comments to see if anyone else thought that too
Mold generally isn't that harmful to digest. It's more of a danger to the respiratory system. You're more likely to get sick from the thought/taste of the moldy bread than the mold itself
( .) - ( .)
He ded
he was just trying to get a dose of penicillin smh
Yeah, he's dead now.
You’re basically just isolating anaerobic bacteria to grow
that's really obvious
Exactly 😆 I wonder if he realizes
Previous experience he needs to be EXTREMELY careful about tasting anaerobic dairies from a vacuum. If he unwillingly manipulated conditions the results could be irreversibly dire (fatal). See canning issues. So unwise....
Beat it nerd
Anaerobic bacteria needs carbon dioxide which a vacuum chamber does not have
next video: will ice cream melt if you keep it in your freezer

# joining the bandwagon
So basically, as NASA and the military figured out DECADES ago, if you want to vacuum seal food you need to dehydrate it first.
this was not asking about mold but staleness. (which was proven to be accurate, it kept the stuff from getting stale) mold aside the apples and bread both showed that they were not stale.
Re-watch the first five seconds.
"A lot of food goes stale OR ROTTEN if they stay exposed to air or moisture, what happens if they stay in a vacuum chamber?" I would say molding qualifies as rotting. So my comment still stands.
dude, chill. this is just a youtube video.
Golly
no u chill
You need to remove the moisture because it fills the vacuum and returns it to atmospheric pressure.Vacuum storage only works with dry foods.
So how do you explain the witchcraft that is home canning then, genius?
@@nesbitt615 canning is usually done with a preserving liquid of some sort not usually dry
@@nesbitt615 actually vacuum just keeps the seal, pasteurization by heating is what keeps it from spoiling.
Not atmospheric pressure. Only the vapour pressure of water at room temperature. That's ignoring any air dissolved in the moisture or other gasses released from the food.
The point is not to keep the pressure low, but to get rid of the air thats filled with germs
You only removed one source of decay, air. There is still tons of moisture in the foods you sealed into a container, which is a perfect place for bacteria to grow
And it definitely wasn't even close to a perfect vacuum.
You have demonstrated that when you pull out most of the air but leave moisture and nutrients behind, microbes that don't need oxygen can grow. This includes yeasts and molds, some of which are quite toxic. This also includes anaerobic bacteria. A common anaerobic bacteria produces botulism. Vacuum or dry nitrogen are great for storing dry things. Moist things, not so much.
This is more or less a more complex explanation of what I was thinking. I was just thinking that dry materials fared better than those with high moisture content.
you're awesome!
Moulds are strictly aerobic
If he knew a little Microbiology he wouldn't have bothered with the experiment
I’m a microbiologist in training and I think I know why the vacuum was disturbed. The answer is not likely that the seals broke or air got in, but more so the microbes and fungus living on the food created their own atmosphere. Many microbial decomposers are anaerobic which means they don’t need oxygen and occasionally don’t even need air to survive. Where you left the unsterile food exposed to unsterile objects, decomposers contaminated the samples and went to work regardless of air pressure. The lack of pressure may have disturbed some of them, but by the looks of it, mostly cells with cell walls survived because the cell wall helps to regulate the cells size and shape, resisting the vacuum chamber. As they broke down the saccharides (sugars) in the food, they created oxygen and carbon dioxide. Also, there could be traces of other gases depending such as nitrogen depending on what parts the microbes and fungus decomposed and what types of metabolisms they use to respire. Water could also be created through respiration which is why the bread may have been even more moist than it was to begin with.
To sum it up, organisms that don’t require air or an atmosphere contaminated your samples and created their own atmosphere within a vacuum chamber.
^Germs in food make their own air where there isn't any.
The first microbiologist I have seen with a Minecraft profile picture
You mean MinecraftBiologist?
Minecraftologist
A microbiologist named SirAwesomeness7? Sure…
a lot bacteria also can only exclusively grow with the absence of oxygen btw...
they're called Obligate anaerobe germs and generally are more pathogenic than those who can metabolize oxygen
The canning jars would have worked just fine without the hole. Their lids already have a rubber ring around them.
Jeffrey Gordon but then how would he take out the air
@@mustansirvasi7167 You leave the threaded part of the lid off, the top part of the lid should seal the same way as his rubber stopper, the same way the Food Saver attachment for canning works.
@@mustansirvasi7167 Leave the lid on just barely enough to touch the rim... That's how you're meant to do it anyways...
@@lawabidingcitizen5153 -----You are the winner. You are absolutely correct. The ring keeps the lid in place. The lid allows air to be removed but locks in place when atmosphere is reintroduced.
Yes it will, unless you sterilize the container and the food.... before you vacuum pack it.
Yeah, air isn't what breaks down food ... it's the microbes in the air.
yes, also the vacuum does nothing to prevent anaerobic bacteria and mounds - which themselves will produce gases and start to remove the vacuum eg carbon dioxide from yeasts.
Aerobic bacteria will not survive long and will be prevented by vacuum.
And sometimes oxygen actually inhibits certain microbes. So vacuum can actually increase microbial growth, if there is moisture present. But tbh, the vacuum isn't perfect if there is moisture left in the product.
(Oxygenated, sterile) air also does deteriorate food. But that process is certainly slower and less thorough than a fine coating of Life.
Lol, no it won't, it will be completely freeze dried and from there not change appreciably for thousands of years if you keep it away from light. Of course this also requires not just that you initially pump out the air but you keep pumping as all the volatiles (like liquid water) evaporate out until there is nothing left but completely dessicated remnants. The microbes that break your food down can't survive without water. No form of life can do ANYTHING without water.
You are using canning jars, they are designed to use negative pressure to seal themselves.
Take the lids and set them in near boiling water for about 10 minutes to soften the sealing compound, then when you go to vacuum seal the lids just put the rings to finger tight, once you remove them from the chamber take the rings off and you will know if you have a proper seal, it's very much like using heat or pressure canning. I would suggest that you redo this experiment properly rather than using a potential weak point such as that rubber taped over the top.
Not to mention that he didn't seem to sanitize them, which could have skewed the results.
Channels like these dun care about proper controls. But there are far worse channels anyway. KOR is still watchable.
It just irks me...
Just a few minutes of research would have told them all of this, lol.
Unlucky Eddy I was wondering y thay did it that way
The jars shouldn't need any modifications if you just leave the ring a little loose. The lid will allow the air to burp out, but will seal the vacuum in the jar as soon as pressure is reintroduced.
You didn’t sterilize any equipment?
Isn’t that severely important regarding microbes and mold when this type of experiment is trying to keep this food edible?
Ristube then it would just be canning....
TBH it isn't about keeping food edible.
It's about whether food is edible in a vaccum.
And here we go
If you're growing mushrooms
He wants to see what happens when it’s in ONLY a vacuum with no other variables
The irony of modifying a canning jar with a rubber valve so it will hold a vacuum.... Literally what canning jars are made for...
lol
Except for you would have to cook the material to create the vacuum rather than using a vacuum pump
Canning jars are just modified vacuum Chambers LOL
Exactly why I came to the comments. I had to see if someone said it because pretty sure all he had to do is leave the lid on loosely and pump out the air. haha.
Actually I own a foodsave that has a canning jar attachment that does exactly the same thing with a small attachment.
The vacuum seals probably equalized within the first couple days. And that's a VERY conservative guess. Basically all you did was test sealed vs open food.
@1919akelbo That's exactly what I was thinking! These are not true vacuums!
Plus he said they might not be perfect vacuums any more... as if he could achieve a perfect vacuum
lmaoo ikr
The mold is proof positive of this. Molds cannot metabolize without oxygen. Putting the bread in a jar with a candle will consume the oxygen and the bread won't get moldy.
Only if he used a sealant to keep the vacuum.
For a true comparison there should have been a third group stored in jars, with the lids on but with no vacuum.
It's just an explosion waiting to happen
This guy gets it. And to the other guy, no… there would not be an explosion.
5:55 Exactly what would happen to an astronaut in space without their gear.
Vapornotsmoke wouldnt their lungs pop/collapse?
Um you know those lids are designed to let air out and not in so the rubber stopper is redundant.
I'm glad somebody said it, lol
BP J I guess not everyone knows how canning jars work.
Except that they drilled a hole in the top, lol.
But he drilled it though.
how would work at all if no rubber stopper was used? what causes the slightly ajar lid to spin shut in your method?
At 7:26 "It's possible we haven't kept a perfect vacuum on all of these". You're correct in that statement. The drilling/rubber seal idea was unnecessary. It would have been easier and simpler if you just placed the mason jar lids on the jars and put them in the vacuum chamber (without the bands). The pressure inside the mason jar would have lifted the lid enough to allow the vacuum to draw the air out. When the vacuum pump was turned off, the rubber on the lid would have sealed the jar. Then you could place the screw bands on. Check out a FoodSaver wide mouth jar sealer, which works on the same principle.
TLDR: The mason jar lid works on the same exact principle as the rubber + electrical tape, and works better.
I thought the same thing. They took canning jars and drilled a hole in the lid, so they could put rubber over it. It's like buying a car, cutting out the windshield and putting clear plastic over it so you can see.
Yeah I'd like to see it again with a Mason Jar, it will be a proper vacuum then
This is what happens when people make a youtube video for the views without doing any actual research into what they are doing.
lol
Next we should have him do a video on food Jarring preservation so we can see his face when he realizes he took that whole other step for nothing!
As a microbiologist, the lack of sterilization in this video is offensive to me
+1
Dundee well you see he doesn’t need to sanitize the jars because any bacteria or other micro organisms will die from a lack of breathable air
@@zecodking2354 well obviously not but that was the test.
Maui Randall kind of
Maui Randall the purpose of the test was to see if it would stay fresh he knew it wouldn't get bacteria but he wanted to see if the taste would be affected
R.I.P Garrett Thompson
Pokes the mouldy bread then eats crisps with presumably the same gloves?
valgarlienheart same observation here
I doubt it would be of much concern, its more of a concern if he were to ingest alot.
His immune system should be more than adequately prepared to deal with any foreign molds or bacteria that had accumulated on the bread.
I think your observation more evaluates the sheer poor quality of experiment being conducted.
Bread mold is just pennicillin.
Mouldy bread is not that dangerous.
Especially molds like the greenish-black one on the bread might be dangerous, as they most likely are a strain of Penecilium. And those molds do not only produce penicilin, but other secondary metabolites aswell which can be toxic to humans and animals, instead of bacteria.
Besides, they spread those substances throughout the whole substrate on which they grow.
6:42 "why was it pressurized!" xD
You know those jars are made to make a vacuum by boiling them and then cooling them.
Yeah, they literally re-engineered the function of the canning lid. They could have just set the lid on and been fine.
Drilling the holes in the lids? I’m like why the heck is he doing that? They are designed to hold a vacuum without drilling!!!
to top it all off I'm pretty sure the gaskets he made would've re-pressurized after a couple of hours...I believe you need to actually clamp the seal down tightly, as is done with the thread on those jars. The tape would be useless...
@@Gocast2 which wouldn't matter anyway since they didn't boil them, meaning the jars also weren't sterilized before they put stuff into them.
they didnt have to do any of that, they could have put them in the chamber with the lids on but loose, pulled the vacuum then re pressurized the chamber. it would have vacuum sealed the jar lid then tightened the lid ring down.
What would happen if you put pop rocks in liquid nitrogen? Would they freeze too quickly or would they still pop?
Pop Rocks work by trapping carbon dioxide inside bubbles within the candy at high pressure. As the candy dissolves in your mouth, the gas is released, and that's what causes the pop. Liquid nitrogen would not dissolve the candy, so it wouldn't pop. The only thing that might happen is that the candy would snap freeze, causing it to crack apart from the contracting pressures and release the gas that way, but then it still wouldn't pop because the gas is contracting right along with the candy itself, so the pressure difference between the gas and the air would be much smaller.
Shaborn Leggette HI
Pop rocks only dissolve in water, so no, they won't pop. And also, the gas bubble of CO2 are pressurized, and liquid nitrogen makes air pressure lower due to the cold temperature, so the pop rocks would lose all the energy stored in the bubbles, too.
Well they're not nitrogen dissolvable
Abion47 omg you monster stip using your mind
You do realize you didn’t have to do all that stuff with the rubber... Those jars are designed to vacuum seal if you just leave the ring loose, and they wouldn’t have leaked. That’s the whole purpose of canning jars (although it’s usually done with steam and not a vacuum pump).
When you steam the jars in canning its basically a type of diy vacuum pump. This is due to air pressure differences caused by temperature differences
Cooking also sanitizes the food and the containers. For something like pickles that are meant to last one or two years, that is a crutial step.
@@NochSoEinKaddiFan pickles are a fermented spoiled food regular can goods last years preservatives or not
Oh, I might have mixed up canned and pickled; woops xD
I think Possert74 and Eric White are right here ^^
@Possert74 do you use alum?
I would really like to see a part two of this where you test what is required to preserve food, specifically sliced/diced fruits, as long as it's whole unsliced counterpart left on the counter. Maybe whole apple on the counter vs whole apple in the fridge vs sliced apple in zip lock in fridge vs in vaccum in fridge vs in sterilized vaccum in fridge?
The moisture fills the vacuum and returns it to atmospheric pressure. It would only help things that are completely dry.
Nailed it buddy.
Yup. In refrigeration we measure vacuum by measuring moisture content.
Am I the only one not caring and still wanting to eat those marshmallows even after they crumpled?
I think that must be the secret to making marshmallows for Lucky Charms. Just inflate them in a vacuum, then put them under 200 PSI of pressure. Instant compacted marshmallows.

Phanes Erichthoneus cuz they have time for that
Nope I would
Oh I would do that... I'm a VERY weird kid
Here's a cool science trick for you guys. After making some coffee, pour it in a room temperature porcelain mug. Right after start tapping the rim with a metal spoon. You'll notice the pitch of the tap will get higher and higher, until the temperatures match. I think it's because the porcelain is expanding. I found this out myself one morning
Thats cool, wouldn't it get lower and lower tho if it is expanding?
@@Jmdeleeuw- when the temperature rises, the velocity of which the sound is travelling increases, hence the increase in pitch ^^
@@Jmdeleeuw- I think your right. I haven't tried it in a while.
Tim's Amazing Yi Bell Here is the experiment but with a metal bell
When you stir the mug you will get the same result. When you pour coffee into a mug or stir it, you incorperate air into the coffee. The air reduces the speed of sound through the fluid, so it has a lower pitch. As the air escapes, the speed of sound in the fluid increases and the pitch increases.
So why did you bother to drill holes into the mason jar lids? The lid already can hold a seal if you do it the correct way.
You should have had marshmallows to test the seal during the experiment

No
Alot of fungi are chemosynthetic, meaning they need no air.

Do raisins inflate in a vacuum chamber?
The marshmallow part was so satisfying and was satisfied 😊😋
you only forgot to sanitize the jars to prevent the molding but other than that great video it was awesome
But what if the mold was fake
molding is not formed from bacteria , mold is made of fungies
there are some anaerobic bacteria that can exist without oxygen. IIRC they can exist in soda cans and if you see bulging soda, it can be a sign of their prseents and you shouldn't drink them.
@steamtrain27 9 *bu dum skraa*
First of all, there are many types of bacteria that do not require oxygen, they are called anaerobic bacteria (like the ones that cause botulism in poorly canned food), and they are basically just as common as aerobic bacteria (those that do require oxygen). Second of all, mold is a fungi, not a bacteria.

Thank you! Very kind thing to say.
Jaylen White Omg tell me your ways!!!!
This has been on my watch later for 5 years
Now try it with everything cleaned and sanitized including your hands.
You won't eat the moldy bread but continued on with the same pair of gloves? Do you even know how mold works? If you did not change those gloves after proceeding after the bread, you literally ate mold off your gloves.
I wasn't really expecting that he'll literally taste anything he tested. And yes, molds don't need to be visible to the eye to be present.
Actually, some of the spores probably did get on his gloves and this would contaminate stuff that he could handle (like other bread and stuff that gets mold).
The point of mold being somewhat dangerous is because of the toxins, and the spores that he got on the gloves even if they had any of the mold toxins, were microscopically tiny and won't affect him any way (other than increasing the risk of contaminating other stuff).
We all have all kinds of spores on our skin and we breathe some in every day, some of them are of mold.
He used different hands when poking the bread with his right, and eating the chips with his left
I eat moldy bread all the time.

Can u dry out a wet phone with a vacuum chamber?
That's probably one of the only ways to effectively dry a phone, actually. I wonder if it would damage the phone, though? Probably the battery, if nothing else.
Yeah probably would be nice to see tho

phxgen yes
the only thing i was amazed by is how the lays bag has no air
Hello everyone and this is your daily dose of Internet and today we'll be looking at this....
Poor experimental design guys, if the variable you are testing is vacuum, the control should be in a sealed jar as well, just without vacuum. Most of what you are testing is "does keeping stuff in sealed jars keep it from going bad"
Observational research is still valid it's just not an experimental research at that point without a control group
Testing more than 1 variable at a time is confusing at best, however.
@@icanthearyoudave true
This isn't about preventing food from spoiling, it's about preventing it from going stale. Those are *not* the same thing.
Or maybe get 2 controls. 1 with the normal jar with lid, and the other which is what we have now.
Did he eat with same gloves after touching rotten bread?

I have always wondered this!
Only I wondered if flesh would rot...
Before the video even started, I said to myself "but what about anaerobic bacteria?"
Anaerobic bacteria laughs at your vacuum seal. That said, "stale" doesn't have much, if anything, do to with levels of contamination.
I just wondered if they sterilised the jars.
Ideally the anaerobic bacteria cannot survive in vacuum, when there is no air pressure. They just don't need oxygen, that's it
I thought anaerobic bacteria can't survive with oxygen but it surely needs some kind of gas and moisture to survive. I think only virus can survive in vacuum.
Wow such a smart boy!!

You don't understand how canning jars work. You don't need to drill a hole in the lid! The lid is two pieces for a reason. Don't tighten the outer ring, the vacuum pulls the lid open and draws the gasses out (and water), then the atmospheric pressure presses the lid down sealing the vacuum inside.
It removes all the air anyway
Maybe a few molecules of air more or less, but both work the same.
And ren't you supposed to put them upside down too?

He obviously wasn't thinking i was sitting here thinking the same thing.
@@thatbigave America in a nutshell
well bread will go bad very quickly if left out. Bread lasts alot longer in the fridge and can last a year+ in Freezer. Should never leave bread out in open.
Take the stuff from around babybels, mold it, melt it, burn it, freeze it
To be clear the reason you got mold was improper sterilization..
Kelsey Robinson Possibly, or the food could itself already have tiny bits of mold.
GMO's
rofl, you know they use gmo to increase food productivity.
cracktober vacuum does remove water. Vacuum doesnot remove solid.
이건희
A vacuum does not remove the moisture in the producht itself.
There are several problems that I see with this experiment. The jars weren't sterilized, the vacuum was unstable, and the food seemed to be cut with the same knife. That allowed for things to cross contaminate or spread from the outside to the inside of that jars. Very cool idea though! It would be cool to see this done again with containers designed for vacuum and cleaner setup.
These jars are LITERALLY designed for vacuum storage, until they altered them by drilling holes in them. To have them work correctly, sterlize them, place food inside them without cross contaminating food. Put on inner lid cover, then screw on ring clamp loosely. Place in vacuum chamber, evacuate air. Remove jar from vacuum chamber. Partial vacuum in jar will hold inner lid cover sealed, then screw down ring clamp tightly. Voila.
actualy thats how you make croutons my dude, bake bread with seasoning and let it sit till its hard as rock
vacuum dehydrating IS a way to store dry goods. If you freeze the food first, you can freeze dry it with this setup.

You guys know they make an adapter that fits over a standard mason jar lid and another size that fits wide mouth lids, they connect to a vacuum sealer by a hose. with the right hose and a standard lid you can do the jars without worrying about the holes or something not working as well. Also warming up the lid a bit by heating in boiling water softens the ring seal on the lids for a better seal.
........mold is absolutely amazing. There are mold spores on basically everything...all the time. They just need the right conditions to grow. And apparently they don't even need air (or at least extremely little air) to grow. I honestly thought the bread in the vacuum would not grow mold due to the lack of an atmosphere. Weird.
Mold is a fungus, and does "breathe" air (more precisely, the oxygen in the air) - I suspected that going in. Like you, though, I predicted that mold wouldn't grow in what's passing for a vacuum here, and was surprised to see that mold seemed to have no problems growing in near-vacuum conditions. I'm guessing there's just enough oxygen left in the near-vacuum - and just enough oxygen in the apples and bread and the moisture in them - to keep those molds going, but I would have still bet against them. They really are, as you say, amazing organisms!
One has to suspect that fungi will grow pretty well in space (and I understand that molds and other fungi are problems inside our space stations!) I wonder how well more organized fungi grow in microgravity conditions, and how well they survive the radiation of space?
There is mold and fungus that doesn't need oxygen to live...
even your own body can burn stuff without oxygen for a bit, lactic acid or alcohol get formed then (depending on the organism)
maybe they should bring some spores over to the iss
Tbh i feel like they used the "wrong" type of bread. There as way too much sugar in there. If you really ant to use the right kind they should've made their own mixture with flour, water, yeast, oil and some salt. It's really easy. Just get the right amounts and mix em together. Let it set for a little for the yeast to do it's job and put it in the oven. Done. Seriously though baking bread is one of the easiest things to do. It doesn't even have to be edible.
though it isn't very likely, there is a risk of botulism. please look up before doing these experiments. potentially extremely dangerous: paralysis, death. someone please let these guys know not to eat this stuff
I was just reading about that from my HSC textbook
The dude splashed liquid nitrogen on his eyeball to prove how the leidenfrost effect would protect him. Sheesh, it's hard to get through to someone like that as they demand to learn things the really hard way. Natural selection trumps again.
And "ate" gallium... Well put it in his mouth "CONSIDER THE BOUNDARIES PUSHED" XD I loved that part
I was expecting the bread to shrink
Yeah from all of the air pockets
It probably would have if he kept pulling a vacuum. Shrink and dry right out
I always wondered about this. Thanks for the video.
He just made the marshmellows from LuckyCharms !!
There magically delishus
This is why jars are hard to open, dude.
I cant believe he is gone, all i know is that he is okay on his own d.i.y cloud base.
This is a perfect example of how/why a broad understanding of physics is very helpful in life.
these were not perfectly vacuumed.
A perfect vacuum is not possible. It would mean sucking out every atom too.
a perfect vacuum is theoretically possible, not in reality though
@@vungocnhatminh6707 "Theoretically possible but not in reality"
@@Berniebud that's why it's called "theoretical"
@@vungocnhatminh6707 What you said was redundant.
Try seeing if flex tape can fix a vacuum chamber
That's a lot of damage
that face and "they're so stale" with the chips...
every poor person knows those feels lol
What if I like the staleness🤔
Should have used a Food Saver with a lid attachment to pull a vacuum. You wouldn't have had to fool around with tape and rubber. Would have been a true test.
Make a jar of marshmallows under vacuum, give it to child, watch their sole die a little as they open the jar to see the large marshmallows shrivel up and disappear.
I so bad want to see someone do this
I want to see the light leave your eyes as you drown in the sea of despair
Its soul learn how to spell
But you know what else will GO BAD in a Vacuum Chamber?
*my life*
lol i feel ya
Wait..... Is your life part of the taste test?
._.
Hehehe LOL
my self esteem... lmao
Can you do this as the next video:put dry ice vs. regular ice in a vacuum chamber and put those in a fridge and freezer for 2 weeks? I would really like to see this
I definitely didn't expect mold to survive in such low pressure!
Keeping something vacuum is actually very challenging, especially over such a long period. What you should do is to vacuum these jars EVERY DAY. Otherwise they might be little oxygen for the first few hours/days, but after that they will be no difference between the vacuum jars and non-vacuum jars. What's worse, unlike human beings, bacteria requires very little oxygen, so those vacuum jars prevented food from drying out (because water vapor can't go out), yet it has enough oxygen for bacteria, so it's oxygen + moisture, which is even worse then just oxygen but dry food. That's why you get worse results from apple and bread.
THIS!!!!!
Yea what he said
If you drill a hole into the lids, then yes, you would have to keep vacuuming the jars every day. But canning lids are designed to form an airtight seal with a vacuum for the very purpose of preserving non-moist foods. There are multiple companies that sell consumer food vacuum sealer systems to do exactly what TKOR failed to do this time.
If the procedure had been done correctly, an oxygen absorber should meet your concerns.
