This is so interesting when you're not "forced" to learn it
where were you forced to learn how microwaves work?
Physics lecture :(
It seems like you use to hate your studies
Not just this.Whenever we are forced to learn anything, it seems bitter but when we are eager to learn anything it seems sweetest thing in the world.
very true bro
Fun fact, it was not a chocolate bar that melted in his pocket, it was actually a nut bar. Whereas chocolate often melts in your pocket anyway, nut bars don’t - that’s how he realised that something weird was going on
It doesn't surprise me that they use misinformation like that right out of the gate.
@@eriklarson4082 the way you said it makes it sound like they did it on purpose. Seeing as this may be a more common misconception, it's not unforgivable so long as they get the science part right, if they were focusing on history instead of science then it would be less forgivable.
@@eriklarson4082 bruh conspiracy against nut bars obviously.
This pleases the nut
That’s nuts!
My GE microwave from 2005 finally crapped out. At first th-cam.com/users/postUgkxO_Bc204MGjxDl87cOKcdgaRhzSqGmv_g I was unsure because I was looking for something with the exact same features. Found it with this one. Interior space cavity was large, but the outside was smaller than my old one. I love the one-button push for 1-6 minutes, and the 30 second add or 30 second start. and MOST IMPORTANTLY, I love how you can adjust the power level during cooking. The reviews said it could not be done, but this marked all the other boxes. and happy to say, it does. I can hit 1 minute start, and change the power level from 10 to 5, 30 seconds in, without interruption. my favorite feature!
Thank you for not having cheesy background music in the video. It can be such a distraction. Loved the video!
It's kinda unbelievable that friction exists at a molecular level. Really, interesting way of explaining. Thanks for that.
Remember this is interesting. The explanation is wrong, misleading and self contradictory.
ofcourse there is friction, in 10th standard we studied about nano technology, do you remember it has so much friction at nano level that's why we can't use it so much
@@chuanglu9162 will you plzz elaborate?
@@satechknowledge2303 are abdul tum puncture banao
@@satechknowledge2303 what he meant was the explanation is self frictioning and produced alot of friction.
You should have explained the Mesh on the window.
It is specifically designed so the electromagnetic wave can't get out.
It does that, by having holes of a small enough size.
(I believe smaller than 1/4 of the wavelength or something like that)
Yes, I was waiting for that as well and was surprised that it wasn't talked about since it is a very important component in protecting you from radiation.
Faraday cage right?
Thanks a lot
Jesus is the Son of God. Believe in his death and resurrection then confess his lordship over your life. Love yall🙏♥️
Yup and also the mesh is connected to Earth
Too easy. At that wavelength the microwave is over decimeter in size, while mesh is like sub-millimeter.
This video explains exactly why I prefer my older microwave. Instead of a rotating plate and a stationary waveguide on the side, mine has a stationary plate and a spinning waveguide above the food chamber, spun by air from the exhaust fan. It distributes microwaves more evenly. Much simpler and far more efficient, and less parts that can break or wear out.
It's why I like my commercial microwave which has two magnetrons and two stirrers and cooks faster and more evenly than any home unit. 2100 watts of microwave energy.
@@jameschristiansson3137sounds amazing! What's the brand and model?
@@Carolina-mw4po We have the Amana HDC212 at our small business. Other brands with this level power include Sharp, Panasonic, Midea Equipment, and Solwave. Some caveats: these are sold for commercial usage. Depending on the manufacturer the warranty will not be honored for home usage. These microwaves require a 240V outlet dedicated to just the microwave. With that said, if you decided to go this route the price may be better from a restaurant supply company rather than someplace like Amazon. Shop around.
This and a video before regarding insulators were both so very amazing and great learning experiences, thank you and keep up the good work.
If I had lesics at high school it would make my physics course awesome, and now I'm learning physics more easily than I did in my whole highschool .
Bro come to college.. I have taken PCME.. Physics and chemistry nothing is entering my brain..
@@KKOBII thanks for guidance dude
yup people like us learn a lot with the visualization, not everyone are liek that, school is made for them not for us
ironic how this video was partially inaccurate.
You're also not a punk teenager anymore and are more receptive to knowledge.
This is how things should be taught! One of the best, most informative, easy-to-understand videos I have ever seen.
Schools should move away from text books and use mostly videos.

I was heating hotdogs in the microwave a while back, and the first time they came out still cold (this one doesn't have a rotating plate). I put them back in, but this time rotating the plate 90°. Left them in for the same amount of time, and bam. Steaming hot. I was so baffled about this ever since. Now I know it had to do with hot spots from the micro waves. Thank you.
You shouldnt be heating anything in microwave, just throw it in the bin. Anything you put in there will taste like shit, absolutely unhealthy. Milk taste literally plastic after heating in microwave 🤢
@@ahabrawgaming1289 You might need to clean your microwave

No, you just forgot to turn on the microwave the first time. It's a very common mistake for Drunk people that want a microwave Hotdog at 03:00 in the morning.
I can’t believe it took me so long to find this channel. This is an awesome animation and explanation. Thank you!!!
"please have a look at these two electromagnetic waves" How nice 🙂

Don't mind if I do
My older microwave malfunctioned once and didn't turn off when I opened the door. My hand closest the microwave felt like the hair was standing up. Didn't hurt or anything. I turned it off after a couple seconds I realized what was happening. Years later they had to cut off my hand due to massive deformities. Kidding.. nothing happened.
😂😜
LMFAO 😂 your name is the cherry on top of this comment 🤣
Lmao the same thing happened to me the other day and that second-to-last sentence got my heart rate up. Ooooh, the jokes 😂
Look at my face! My mom peeled of the protective film on the glass door of the microwave when I was a baby. She would warm up my milk every day in it, with me in her arm. Yes. My face was right in front of it. By 9 years old my face started to deform. My profile picture was taken in 2015. No joking here.
@@Elaba_ Just my face. If you look close, you'll notice how bad
Things I learned from this that no even talked about in school or even university/college:
Reflected waves is 180° flip along Y axis of the wave that would have propagated if there was no reflector.
Heating using microwave is caused my friction due to oscillating water molecules.
The L=N*wavelength/2, it's application.
The standing wave application in a more easy to understand way.
And lastly it was in a fun and thought provoking manner.
Seriously. Best explanation ever . Thank you!
Me suspecting that chocolate with water molecules started to melt
But the man with 70% water
You got the point lollllololololool
Well I guess chocolate melts much faster than man.
@@Chirag.D da fuq kind of bs is this? 🤣
@@Chirag.D complex proteins and skins ?? What is that supposed to mean ? First of all, the chocolate didn't get cooked it just melted. Humans have a large surface area and higher heat capacity so I think that is why the scientist didn't feel any effects as the heat dissipated quickly. If you have a powerful machine it can and will literally cook you from inside out if you come in the way of the fields.
Hi might have felt his skin getting warm, but not thought anything of it.
The actual answer is we have heat sensory nerve endings in skin mainly, and skin doesnot have much water. So it didn't heat up, and he didn't feel the heat.
Water is mainly in blood and internal organs, which don't have heat sensing nerve endings. So even if his organs get cooked, it would take very long for him to realise that
I wish this person was my physic teacher back in high school, it would make life much more easier and less stressful to study my other 9 subjects at that time
Amazing! So, i could learn that a standing wave is concerned by 2 microwaves interfering on each other. A first microwave (incident) is created from an electric source and flows through the resonance cavity. When it finds a reflector, the first microwave reflects and creates a secondary microwave in opposite way. The phase of the secondary microwave is 180 degrees distant from the first one. Implies that at this moment one phase is canceling the other when the amplitude is maximum and minimum, one to the top and other to the bottom. But as the 2 waves is travelling, the distance between the phases isn't static, so when the 2 microwaves encounter at the moment of maximum amplitude for both of them, they interfere constructively, point of maximum energy. That's the reason that the standing microwave formed is applying more energy always at same points, cause the distance between phases is varying, but as it's originated of the same source, they have the same frequency, velocity and amplitude, the points of maximum amplitude of both of them will always be the same. Interesting that the encounter of no amplitude of them, don't create more energy at all. But as microwaves flows, that's the point that they encounter constructively. It was not common sense to me. Thanks!
What bothers me is that the cheese shows multiple hotspots. This is contrary to the picture of a single standing wave. If there is a single standing wave in the cooking (resonance) chamber, then we must have 2 or 3 or 4 hotspots aligned in a row spaced at equal distances. Right? But this is not shown in the "sea of cheese" plate..... I am confused.
@@TobyOnTube thas caused by the rotation of the plate, wich allows the hot spots to warm the cheese in other points
@@Mateus-gt2iq: Thank you, but I have to disagree. If you look closely then the experimenter places a square-shaped tray into the oven. It's impossible for it to rotate within the oven chamber given its size. I hope you agree on this. However, your answer could also be interpreted for the case where there is a fan rotating in the ceiling of the MW oven (randomly?) distributing / reflecting microwaves within the oven while the food is stationary. But also this can be argued against because if you look closely the model has the design where food is rotating (rotating mechanism at the bottom). So, if I am correct in my chain of arguments, then the food (cheese) is stationary, the generated microwaves must also be stationary (no reflecting fan in the ceiling). Hence my original question is still open..... Looking forward to your reply. :)
@@TobyOnTube I misunderstood you, you made a good point. I just realize that some microwaves has a rotating fan that spreeds the waves in other directions, i didn't know about that, thank's. The combination of the inclination of the fan blade and rotation, cause waves to travel a 3d shaped pattern. I tested by myself at home, my microwave just have the turntable, so waves is really stationary. Maybe some microwaves has turntable and rotation fan , makes sense to me
@@Mateus-gt2iq: Thank you for a constructive discussion. What I do not understand is that the hotspots melted into the sea of cheese are not arranged as expected: if there is a single standing wave with travel direction along the left-right axis of the oven, then I would expect 3 or 4 hotspots at equally spaced distances around the depth where the waveguide is located (at the upper right side). But this does not seem to be the case. Its kind of a pity from a didactics and educational point of view: In the 5 - 10 minutes before operating the microoven you imprinted a picture of a standing wave in the head of students, but then the hotspots are not where they are expected according to the standing wave picture...... I hope you understand my point.
Nice description of such an interseting engine. It is nice to understand magentron exist and how electromagnetic radiation work. Also, it is interesting to see what radiation use in order to heat up food without hurting health. Finally, nice the approach of reflecting waves in order to get advantage of their ability to penetrate food.
Good video. You should've covered the wavelength size of the 2.45 ghz vs cell size of the metal seethrough mesh of the front door, that would be a good explanation why microwaves cannot penetrate that mesh. Maybe even cover induced harmonics in it too just for fun.
YES that is exactly what I asked but now you've explained it so I understand LOL
2.4ghz is actually the wavelength of Wi-Fi routers and 4g cellphones. Interestingly cell phone radiation is considered a possible carcinogen by the national cancer institute and a lot of scientific studies have been conducted to confirm this. Not sure about microwaves but I dont like the idea of having one right next to my head like the ones they started putting above the stove.
@@archive8080 "a lot of scientific studies have been conducted to confirm this" -- that's a convenient way of saying "I don't actually read, but if I do read, I don't actually comprehend what I've read".
From your very own source of National Cancer Institute:
"In 2002, the International Agency for Research on Cancer (IARC), a component of the World Health Organization, appointed an expert Working Group to review all available evidence on static and extremely low frequency electric and magnetic fields (12). The Working Group classified ELF-EMFs as “possibly carcinogenic to humans,” based on limited evidence from human studies in relation to childhood leukemia. Static electric and magnetic fields and extremely low frequency electric fields were determined “not classifiable as to their carcinogenicity to humans”.
@@acmilanshevachels that's what I said, possibly carcinogenic. "I dont actually read", obviously you are projecting. If you want to challenge my claim, we can get into it. If not, take a step back and wait until you've seen the evidence before making judgements.
@@acmilanshevachels wow… do you think this is a toxic “politics” TH-cam channel??
I find that people who are as pompous as you, concerning engineering matters, are usually the ignorant ones.
Explained really well.
Highly appreciate the effort for making the video!!
Such a great video I learnt microwave heating with full clarity .Thank you so much .
Sir, it was really a wonderful explanation. One should know all the basics of Microwave oven technology before using it. Thank you.
Your efforts in making these explanatory videos are incomparable
Thanks a lot
even first-grade students can also understand easily. Your seamless teaching style is assisting millions of students. I do respect your hard work, determination and teaching style
@CIA,DOE,NSA,DOD, & Research Institutes test on You yo i thought this and now i studied some EMF propagation at school. this is so messed up.
They excludes the _MATHS_ behind it
Omg how easy to understand the wave motion when i never can inagine it moves like this. The animation made the story clear to me
this was a perfect explanation. Thanks a ton!!
The cooking from the inside part just isn't true. The strength of the wave inside the food is of function e^-x and the more inside you are the weaker it is. The inside gets heated by the little wave strength that is there and by the heat passing from the outside to the inside. Put anything relatively large in the microwave and cut it in half after heating it. You will see that its colder on the inside. That statement really killed the video for me...
Yeah, unfortunately it isn't entirely accurate. You still do get better heat penetration in most circumstances though.
yep specially if you want to heat thick liquid such as soup. I've tried various brands of microwave oven to heat cold soup, unfortunately none of them are effective at the moment.
That has everything to do with the microwave in question. Commercial ones use multiple magnetrons for even more efficiency.
There are some exceptions. For example a jam filled doughnut. In fact, because of the lack of H2O in the dried out bread and the abundance of H2O in the jam center, all the microwave energy goes towards heating the jam. It is in fact quite dangerously deceptive, as you'd take out the jam doughnut and it will feel a little warm, but as you bite into it you'll get a nasty surprise because the center will be extremely hot.
Also, as cardboard and plastic do not contain any H2O there is no effect of heating resonance from their molecular structures. This is easily demonstrated by heating pizza in a microwave while still in its cardboard box takeaway container. The cardboard is not hot, yet the pizza is.
@@RoySherfan This phenomenon is what makes Hot Pockets so hazardous.
Really Love the video, very informative, can imagine how much hardwork went into the animation and stuff, thanks guys for making a normal person more educated, specially in concepts that touch upon our daily lives. 😀😀
Skin depth concept is also used in this..
Wow this is so fascinating i wish you made a video about how magnetrons work .
This was explained really really well. I wish schools taught this was. I would definitely like physics.
Nah. I excel in physics just but looking at examples and reading problems & solutions. Those who think "schools taught" instead of "students learn" are usually stupid, and stupidity is the real reason they don't like physics.

Amazing explained with clarity
thanks for clearing my understanding of microwave oven
Well done! The microwaves are confined within the cavity due to the metallic mesh attached to the door glass . Without it, microwaves will escape.
They still escape. Check it yourself with a microwave freq reader. I did and have found them to escape. They could be picked up on the other side of my house.
@@Stefano-tb8ls Are you actually checking the electromagnetic waves? If so, many appliances do that.
@@Stefano-tb8ls Check your microwave freq reader with your microwave disconnected and you will still find 2.4~GHz
They definitely still escape. Whenever I use Bluetooth while the microwave is on it gets disrupted even when I am standing over 5 feet away. When the microwave turns off the Bluetooth goes back to normal. I think these microwave companies are lying to people to make them think it is safer than it is
Great video. Would've wished for some details on how the EM waves are confined inside the microwave to protect us from harm.
That would be fiction.
@@Living4YHWH but not really.
Since metal basically reflects the waves back, the inside of a microwave is built out of metal which doesn't let the waves pass through (as they reflect back in), same with the glass that most probably contains a thin layer of metal which does the same job. And so the waves never go outside of the microwave oven but remain inside throughout the duration. That is the reason why, when opening the door to the microwave oven while it is working shuts it off, it's a safety feature as to not allow the waves to go out of the microwave since the door isn't there to reflect it back anymore
@@Living4YHWH He was asking about the function of Faraday cages, not about the existence of your brain.
@@Nawmps 🤣hell yeah dude
Very knowledgeable... thankyou sir
Excellent. Thank you so much.
My favourite channel from all my subscription feed.
Never mind the melting chocolate bar in the scientist's hand, he should probably stop playing with microwaves and go directly to the emergency room based on what looks like 3rd degree burns!
Na, that is the chocolate melting
it´s a chocolate bar... not an metal bar... no need to have such amount of energy (heat) to melt down
@@germancampos6265 Thank you for easing my stress! I was concerned the scientist may need reconstructive surgery.
Interesting that the microwave oven was sort of praised at the end there. I always felt that the way my food came out of a microwave oven left something to be desired, and that it didn't stay hot long enough.
I stopped using microwave ovens almost ten years ago, and I don't miss them. I reheat all leftovers in my toaster oven or in my propane oven, and occasionally on my propane stovetop.
I find that it preserves the original quality of the meal. Usually I put the food in a casserole dish with some foil on top, at least to begin with.
Agree! I’ve never owned one. Everything came out of that thing limp and unevenly hot. It only takes a few minutes to heat things in a toaster oven or on top of the stove. Are we really that impatient?
I have not used a microwave for @ 12 years now. din't miss it either.
Amazing explanation! Thanks!
Do you guys ( I am referring to Lesics Team ) realise how fantastic you all are and how easily , from " very interesting day to day phenomena " to " complex engineering marvels " are explained on this channel !
It's just AMAZING !
thank you for all the hardwork that are put into EACH & EVERY video 😄& Wish you guys muchhhh moreeeeeeeeeeeee SUBSCRIBERS !!
🤩🥳🎉🎊
And, of course, if you're teaching the kids about electromagnetic waves you can use a large slab of chocolate as shown to get the hotspots (disable the turntable first). Then measure their spacing and with a bit of detective work on the frequency and very simple maths they can calculate both the wavelength and the speed of light. If successful, they get to eat the experiment. Might have to do it more than once to get a spread of clear results to average (!)
Thank you for raising this issue!! What I do not understand is that the "sea of cheese" apparently shows some random field of hotspots suggesting multiple standing waves. This is contrary to what the video tried to convey: a single standing wave. If there is a single standing wave, then there should be a regular-spaced pattern of hotspots in the sea of cheese. Hope you have a good explanation. Because from looking at the sea of cheese, I cannot make out which distance to measure.
You gain a subscriptor with that understandable explanation
Nice video, but i think it skips over the most important questions
* How does a magnetron work?
* How does a waveguide direct the waves in one direction
* How does the microwave chamber prevent any waves from coming out?
I understood resonance along with working of oven......... Brilliiant explaination

Video: "Cook from the inside out"
Me: True, you can boil water even if it is inside a covered small ceramic container. And the ceramic wont became that hot, only the water will start to boil. But for a large chicken you need to adjust the wavelength a bit so it penetrates deeper and add a couple of watts to cook a whole chicken, but then you have it. Did not hear that detail in the commercial :-)
"Cook you food with good uniformity"
My microwave: so I'm actuality adept of the Ying and yang philosophy
Thanks for the history as well
Amazing learning animation method. Easy to understand
Nice I was looking for it.
One important thing to mention.. Never ever put a metal in a microwave oven. (my 6yrs old son asked me to write it)
Reason?
@@thehaseeb9136 Metal reflects the waves which can reflect back towards the magnetron and damage it causing sparks and a fire.
Forgetting about a foil lining in a wrapper has ruined a few sandwiches for me... Before you can even shut the microwave off it's too late, your food already tastes like burned metal...
another important thing to mention: never let a 6 years old near to that microwave oven (health hazard, EM radiation is damaging your tissues )
@@needsomehike when we open door of oven to take out food, will it harm us? My mom leave door open for some seconds after taking it out and microwave oven was off but light was on
Funny how i used this as an insight to my theis research, thanks a lot buddy
I love this .... thanks a lot
I don't understand how it can be concluded that a microwave cooks from inside-out. When the micro-wave comes in contact with the food, some energy first gets absorbed at the surface before going inside the food. So, a better conclusion would be that the food gets cooked evenly from inside and outside. Please correct me if I am wrong.
Maybe it is due to the water content because when you keep for outside the surface molecules evaporate first but the innermost molecules almost do not evaporate. More water = more thermal energy absorbed, therefore I guess it depends on the water content inside the food.
@@aumpauskar4653 Nicely explained. But if the food is layered such that the outer part has lot of water than the inner part, the food does get cooked from outside.
So I guess it is more appropriate to say that the food gets cooked evenly, both inner and outer part recieves heat.
Also read: why is no 2 parts of my HotPocket the same temperature?!
RF currents flow below the surface
@@longbow6416 Because of the difference in water content within different parts of the Hot Pocket. The filling inside has much more water in it than the bread on the outside. Even pieces of meat within the filling are going to heat differently than the liquid part.
Great video! Maybe you could explain in another one the Faraday cage used to trap the microwaves.
Very informative. Thanks for sharing.
Very important information for better understanding an important everyday device.

That is why viewers will automatically subscribe your channel . Great job sir and happy learning 😊👍🏻
Great work as always.
Aspects i had loved to see also:
The mesh cover on the transparent screen
Why (even it is implied) you shouldn't put metallic elements or coatings into a microwave
Why water sometimes don't boil in teh microwave but instantly when you move it the slightest
And maybe a mention why you really shouldn't try repear it yourself (also implied, i know)
These are common aspects people might interest in to understand, know about, or advance ther understanding of the 'classic telling' about the device.
I am now understand clearly how these microwaves are being produced by this device .thanks
Thank you for this nice explanation.

Who tf is cooking a turkey in their microwave
Mr Bean
only if the microwave is made in texas, its possible
Good sir, i ask you why not ?
Some are two in one
I think it was back in the 60's that... *everything* was cooked in the microwave. Whole cookbooks on recipes, just for cooking in the microwave. Yes, including turkeys.
Microwave heating is not uniform, unless you're only heating pizza...
Not even pizza is heated uniformly
Newer microwaves come with this small fan installed on top to spead the waves some more idk if that actually works tho
Pizza is best re-heated in a toaster over or a pan.
Microwaving most food is kinda gross.
It's good for warming up food to cook in an oven or on the stove, but not by itself.
That's one major problem. Also when we need to heat large quantities gas stove is best.
meaning it time for you to get a brand new latest model. 🤣🤣🤣
Your channel is all about how appliances work
OMG!
I was knowing about the working process of Microwave, but not this much deep.😀
Fantastic video 😊👍
The animation made it more easier to understand such a complex working of microwave.
Did anyone notice 'Amul Cheese' at 6:00? That is from India :)
Yes I did
A silky voice, a good script, some lovely graphics and we're all sold.
learnt something new today
6:25 - Finally someone explained in detail how exactly a food microwave works.
So the greatest peaks of the microwave’s amplitude is the one that creates hotspots? It would make sense since all peaks in a wave has the most energy. What would happen if the peak of the microwave is below the food? As if the peak of the wave is actually greatest at the surface of the microwave oven’s floor and not on the surface of the food? Maybe the microwave oven is designed such that the peaks of the wave will always remain at the level of the surface of the food…
the standing wave pattern of a 1D system is simple,
the standing wave pattern of a 2D system is a mess,
the standing wave pattern of a 3D system is hell, it is next to impossible to "design" the cavity in any meaningful sense other than just make it and ok if there's no fatal flaw.
"The electromagnetic radiation is always confined within it" - except when it's not. You can measure leakage and older microwaves leak more.
The leakage in older units is minimal, and typically around the door release lever, or if the door or seal is damaged. However, these tiny hotspots dissipate quickly with distance, so normal moving around a kitchen would result in only very low exposure.
Never heard of this Megnetron before. Is he an Autobots or Decepticons.
Decepticon
Physicists and electrical engineers are rock stars in my book.
I just realized that "microwave oven" is a real word. I thought it was just microwave

"...and with good uniformity"
Pasta tends to disagree
All videos super pls explain for ship engine and how to working
Very interesting and fun way of explaining scientific facts!!!! Kudos to the team💪
Amazing! Now I'm a professional microwave cooker 🙂
There were way too many inaccuracies in this video. The most glaring one was cooking from the inside out. While it is true microwaves penetrate food, they are attenuated fairly rapidly and so do not make it to the very center of a mass of food item with any appreciable volume. Microwave ovens still rely on conduction to transfer heat from more outer regions of the food to more interior regions. That’s why the defrost program typically cycles the magnetron on and off. (Inverter based microwaves excepted which turn the power down thus allowing time to conduct heat to the interior in a similar fashion)
But how bro, I have read in books microwaves have larger wavelength than red light, infrared. Then it will easily penetrate into most food items.So heating should start in the reverse way u mentioned.
I am just saying my opinion (school student). Any reply is heartily welcomed.🙂
@@thepredator4711 check the Wikipedia page on microwave ovens. Without going into the physics of the what and how attenuation works, it penetrates food about 1-1.5 inches deep so anything thicker than 2-3 inches depending on the oven will end up with a cooler center.

Okay, that's only one, but you said above "There were too many inaccuracies". Either list all inaccuracies or better edit your comment.
Unrelated to video subject :- Microwave manufacturing companies know this fact, so that's why they sell only standardised sized microwaves to prohibit customers from putting very large food samples in microwave and uncover the lies of their market campaign by themselves. [DiowE]
Can you explain me there are how many inaccuracies except this one?
