it's because they know what's out there
I don't get it
@Afif87123 the microwaves would rather stay out of our society
@@Afif87123 he's talking about people on tiktok

🤷🏼♂️fair enough
This is actually an outside of the box idea that works. I've always wondered how my boy Riley hasn't run out of ideas yet.
Pretty sure the idea is INSIDE the box
I thought it was Jon who wrote all these Techquikie videos. He’s still listed in the credits as the author and he’s been writing for this channel for a long time (maybe the longest in LTT’s remaining legacy staff). Although Riley and other hosts may edit the presentation, I always assumed that the core content of these videos were researched and written by Jon.
Creative people have the opposite problem. There's too many ideas to ever bring to reality. Some are dumb, some are amazing... and it's a learned skill recognizing which is which.
@@AbiRizkypretty sure it's inside the microwave
So Techquickie is doing science now? Honestly, I'm here for it.

@@AmEv7famCan't wait for techquikie doing calculus II 😂
Can't wait for techquikie explaining how cloths can stop the spreading of covid.
@@AmEv7fam Understandable, but *Tech*-quicke has always been *tech*-focused. It seems to me like this is one video that lies solely in the Science realm.
@@Rem_NLnice bait
Moreover, the reason there is a gap between the glass window and the mesh is due to evanescent waves: an exponential decay of the field strength outside the waveguide (in this case Faraday cage). If there was no gap, you could cook your skin by putting it up against the glass
Timing was impeccable. I’m using my microwave right now. I was just thinking about how it works.
Hmmm… what a coincidence. I hope you enjoy your meal.
Your microwave is transmitting back to home base at UA-cam.
My old microwave used to affect my old CRT monitor through a wall 😳 I could always tell when someone was using the microwave.
Probably because it drew allot of power
Yeah, that would be the AC flipping the strong magnetic field produced by the magnetron / transformer on the microwave. This interrupts the electrons between the CRT and the phosphate film on the screen as it overpowers the weaker magnets that are used to aim the electrons while it scans.
@@Carhill impeccable explanation 🤌
I remember that.
Wait for the commercial to make popcorn was the rule in our house.
The crazy thing was, as a kid, I had a toy microwave that ran on C batteries.
It caused the same kind of interference on the TV as the real microwave.
Believe it or not, the older a microwave gets, the more likely it will "leak". I haven't been able to pin down why, but we had a work microwave that would knock out the wifi in the breakroom. Bought a new one out of snackbar money, and viola!, wifi was good to go.
I have no idea why they're covering this, but if you enjoyed it, look up "technology connections". I don't care about the science behind kitchen appliances but I still watch all his videos because he's so entertaining.
or look up "styropyro" and check out his over-powered laser-based "microwave" and the resulting cuisine.
Tech Connections is like my nerdiest of my nerd channels, and for some reason I'll listen to an hour dissertation on electric kettles or LED Christmas lights.
Hey LTTeam, I feel like i've noticed an increase in host speaking errors being corrected by text on screen. Would like to see the scene reshot instead, which would feel more appropriate to your usual production quality
Maybe they find it difficult taking into account the increasing number of videos per week. They already said they had tight schedules with 25 videos, now more with the new channel game linked
With what they have to do to keep afloat, I'd rather they put out a video with a text correction than put out no vidieo.
@@raistlinmajere1000 IMO if the production value is falling, they are expanding too quickly
I agree, but for the production cadence that their company runs at, its a lot easier to just write in a correction.
Must be the new CEO "churn em out chop chop chop more viddys = more cashola go go go"
Did you know the USDA has instructions for how to microwave a turkey? For a 14 pound turkey (the largest most microwaves can accommodate), you need to cook it for 126-140 minutes (2 hours 6 minutes-2 hours 20 minutes) at 50% power.
ew
Meanwhile Shaggy can eat a 14 pound turkey in 2 minutes using 5% of his power.
@@gamagama69sigh, there's Two types of microwaves. If you have a CONVECTION food comes out pretty normal. That $39 dollar microwave isn't going to give you crispy skin turkey.
:D 50% of what power? :P Every device can have a different maximum power.
If microwaves stay inside, why does it affect the WiFi signal?
Because they aren't perfectly sealed. A little bit of the radiation does tend to leak out around the door, but nowhere near enough to be physically harmful to people.
Some microwave ovens, especially older ones, don’t block 100% of the microwaves from escaping and it only takes the tiniest leak to interfere with Wi-Fi. Not a problem with 5Ghz Wi-Fi though
There may be small manufacturing defects, damage over time, or perhaps just poor design / manufacturing (low quality product). These would all lead to leaks, and given the magnetron operates at ~2.4GHz in order to excite the water molecules (as well as some fats and sugars), it can conflict with your Router / Access Point that utilizes the same EM band.
Small leaks aren't harmful.
I was wondering the same thing. Thanks for all the smarty pants answers everyone! 💯🔥
@@ShaneH42 - Not to mention more modern microwaves are much better at sealing the waves in, which is why "microwaves interfering with WiFi" is... well, not really that much of a thing anymore.
As a side note, I don't really remember it ever affecting wifi - by the time wifi was common, I think better seals were already in place. The main issue older microwaves coincided with were cordless home telephones, which they absolutely did harm the signal on.
This was great. I love broadening tech quickie's scope like this.
Riley's jokes are a lot like microwaves. They always hit the right spot and nothing else.
I don't have a microwave oven, I have a clock that occasionally cooks stuff.
really balanced explanation. casual enough, but still enough technical details and correct facts.
As a science educator I have to disagree...
never thought id see a Techquickie on microwaves
From what i know, those tiny holes on the door block the rays from going outside. Its actually genius and useful too. So we can still see inside!
I remember wiping a CD in a microwave. Don't do this with a microwave you care about, but do watch it if you do. It will glow brightly around it a few times. The smell and fumes are probably not good, and the smell continues to linger when you use the microwave for a few days.
That's burned plastic, absolutely bad to inhale. It can stick in your lungs forever.
But storing radioactive materials in household appliances was my favourite method, Riley.
Guess I'll have to store my radium in a toaster oven then
Have you seen the prices for radium these days?? I always store mine in the safest possible place--stuffed inside my mattress.
@GSBarlev yes, but, have you ever seen the episode of spongebob where Mr.Krabs has his money hidden in his mattress, didn't go well for him. Can you think of a time someone stole anything someone had stored in a toaster?
@@gqinc1202 the joke here is that Radium is highly, um, radioactive, and storing a large quantity centimeters from where I spend eight hours a night would make me a strong contender for this year's Darwin award.
@GSBarlev i sleep on a pile of radium filled toasters with lead lined sheets, wouldn't want to be dangerous now (also the toasters are plugged in to keep the bed warm)
radiation does in fact leak from the microwave, we have the same 'good enough' design as they had back in the 90's, and there is some leakage which results in interference with wifi and other devices on the 2.4 ghz band. but this is a non issue from a couple feet away.
I use wireless headphones and can't get too close while nuking something, otherwise the signal gets distorted or even disconnected
Best simple to the point explanation I've heard 👍
Please make more science videos like this, and more programming and web stuff, your content is too good for what's new in windows 11
More of a science quickie, and I knew all this info, but I like this angle and hope to see more.
Correction, it CAN (Sort of) explode I know from first hand experience. My dads work got one of the early somewhere in the late 80's for their breakroom, my dad took me to his office after most of the other employees had gone home when I was around 9-10 years oldish. We were there for some time, and a few hours in I was bored and hungry, so he showed me how to open a can of spaghetti-o's and meatballs and put it in a bowl and then microwave them. One delicious meal later we went back to his office for a while where I returned to being bored for about 2 more hours. When I complained about being hungry (probably more bored then hungry) he handed me another can and sent me to the break room when I opened the can and microwaved it... If you caught the missed step you were more observant and less ignorant of these new fangled things called microwaves, I left it cooking for like 5 minutes (early microwaves where lower wattage) and went back to my dads office, when I returned to the breakroom and opened the door, the microwave was dripping flames from the top into the can of spaghetti-o's... My dads company banned the bringing of kids to the office for probably unrelated reasons about a month later...
Interesting choice for a Techquickie video
This...this may be the greatest question of our time...
this was really interesting. would love to see other videos like this in the future
I have a defibrillator implanted, so I have to stay at least 6' away from any running microwave. sure, they may not be dangerous to you, but they can easily kill me.
I always wanted to know where the waves of a Microwave hit the food. I found when I made scrambled eggs in the microwave that their radiation pattern is exhibited. When cooking scrambled eggs in a microwave the eggs cook in a bunt cake pattern. Meaning they cook in a ring and fluff up in this ring. You cook for 30 seconds, then stop and stir the cooked eggs mixing the cooked and raw eggs together. Continue cooking and stirring for until its all cooked to your desired doneness. Somepeople like wet or damp eggs, others like their eggs like little golden nuggets. In the last 30 seconds add cheese, onions, green peppers, chopped ham and salsa. A quick and easy Denver like omlet.
I already knew what the mesh was for but I didn't actually know why the mesh worked thanks for the info!
This channel is real tech channel, which is not limited to smartphone unboxing 😊😊
You have amazing editors.
With reference to the comments at 1:30 about heating up the food, I immediately thought of an observation in a Chris Brookmyre novel. One of the characters has a theory that microwaves actually heat up crockery, and the warming of food is a mere by-product.
Loved the cartoon clips showing how to catch a microwave in the wild with a metal box & a popcorn as a lure. I will have to try that 🤔
The mixed use of metric and imperial units in this video makes me die a little inside
While most microwave ovens use the 2.45 GHz ISM band, there are some industrial microwave ovens that use the 915 MHz ISM band. That band is more penetrating and it's only available for use in ITU Region 2 (the Americas) so it never got used for home microwave ovens.
Riley, you’re awesome! Been watching your videos since before Linus “found you the dumpster”. Keep it up!
darn I was sure my 10kg radium was safe in the microwave XD
You're building something there bud?
@@AbiRizkyAre you as Curie-ous as to what he's up to as I am? Well, I'm not about to start Roentgen about safety precautions--that would make me a complete Bohr.
@@GSBarlev man I thought I was a nerd
Then why does it jam pack the 2.4ghz band?
cause 2.45 is very close to 2.4 as such there are more chances of the wave lining up and interfering with eachother.
Microwaves tend to be cheaply made, so they can be leaky.
That was some excellent editing there!
One thing I've always wondered is why US microwave ovens are typically 1100W, but in the UK, they tend to be 700-900W. I currently have a 1000W UK combination microwave, but it was hard to find one with that power! It seems stupid that UK folks are offered significantly lower powered microwaves when the only reason they exist at all is for their speed of cooking!
Probably because UK microwaves are smaller, just like most other kitchen appliances are too like the fridge and oven. I live in Canada but come from England, and everything feels huge compared with home.
...and it's why everyone used to lose WiFi signal near the kitchen when the microwave was running. :) (the 2.4ghz bands.)
I love this, thank you!
It's ironic we call them MICROwaves when they are some of the biggest waves.
Feels like we named our waves backwards
bruh infra-red light aint even red we suck at this shit
There are far bigger waves though. FM radio waves are like 100 times longer, shortwave radio 100000 times.
The are so named as they are far smaller than the radio waves that were first produced. They are very small and high frequency in comparison. Radio waves are kilometers long.
@@SnareGG "infra" means below, so the frequency is lower than that of red light.
@@SnareGGThink about what you just said.
at my old job, the faraday cage on the microwave's door had a hole burned in it (maybe 5mm x 20mm) i was able to measure it from outside (the the metal detector phone app) i got a reading over 100 uT, with the limits for non-ionizing radiation being at ~90uT to the head and 60 to the body, that put it outside those limits. essentially, lightly cooking anything within a foot of that hole.
I reported it to management, who neither understood nor cared
Next week on the LTT channel, "How to overclock your microwave for more performance" after this ad from our sponser.
Is it possible to beam electricity from a microwave to, say, a drone for unlimited fly time using microwaves? Maybe all that is needed is to have the drone communicate with the beam so it can point it at the drone and also make the drone out of metal or at least have an 8 inch wide spot to focus the beam on for electricity?
I saw a demonstration with a meter, showing higher readings within a few feet of the unit.
That's right, standing next to a microwave.
I wish I could locate it to tell you where. I don't think it was Technology Connections
One science website (YT shad dough bands when I posts URLs):
"However, while there should be almost no radiation escaping from the chamber, it’s best not to press your nose up against the door the entire time your food is heating up. It’s safer to stand on the other side of the kitchen so your exposure is reduced to none, he said."
What?? It's best to stand on the other side of the kitchen??
What's the problem? Some microwaves can leak a little, it's fine.
Linus showed interference from the oven while tracking down that wireless speaker issue in one of the videos here.
also are the microwaves within the device standing waves? im not sure about it, but that would explain the rotating plate within, which would help with heating up the food evenly, as it always moves around (tho not perfectly)
I worked at a bank drive-through that had a microwave that would operate with the door open. My friend and co-worker demonstrated this party trick during my first day on the job. We always cooked food with the door closed. I'm not too worried. I grew up living just south of a row of refineries. That probably did a lot more harm than a few seconds with an open microwave door. 😏
Always love these, mostly because of Riley!!
You missed the perfect chance to sneak in a Steins;gate reference on leaving the microwave door opened.
0:15 *In my best Jim Gaffigan voice* _hooootpocket_
Absolutely love it when you can laugh and learn something
this is genuinely everything i was too afraid to ask about microwaves
Ever since I heard microwaves make water molecules spin, I thought it was a machine that is a magnet, switching from positive to negative 😂
But certain types of low wavelength light just has that property, so basically microwaves actually radiate a type of invisible light or electromagnetic radiation (basically light)
I have worked in a few offices where the wifi goes off when someone turns the microwave on. The 2.4Ghz explains it. Guessing they have a cheap microwave that is not shielded correectly.
"Hulk loves Gamma Rays"
The microwave oven is basically a cavity with length equal to one half the wavelength of the EM radiation being used so that a standing wave is supported in the cavity. It is basically the same concept as an acoustical wave in a musical instrument.
Wouldn't that wavelength change once you put anything inside the oven? How does it stay resonant?
@@shanent5793 The food you put in would definitely have some dielectric constant associated with it and would shorten the wavelength some but by how much I really don’t know. It would depend on the index of refraction of the food at the microwave frequency range. I’m sure there is a certain bandwidth associated with the microwave emission and it isn’t a perfect dirac delta function. So whatever change in the effective resonant wavelength the food causes is likely within the bandwidth of the microwave energy source.

You forgot to mention that your WiFi uses the same frequency. Also some radiation does leak from a Microwave and drops off after approximately 3 feet from the device. I have an EMF detector and have tried it. It doesn't seem to matter which side of the microwave either, it goes through the wall behind it and drops off at the same point. So, stay at least 3 feet away when you are cooking, but keep in mind that your body is large enough to dissipate the heat at that distance, so it is not likely going to burn you.
The radiation does not leak beyond the microwave....sorry. Good try lying though =)
Has to be more than 3'; my router is farther than than and so are devices.
@@drunkhusband6257 Would you like me to post a video of the alarm going off on my RF meter?
@@LilRedDog Yes, a router goes much farther than 3ft because it isn't inside a faraday cage, but It is also many wats less in power. That being said, it isn't necessarily the frequency that drops off after the 3 feet, but the power dissipation. I was repairing an old portable TV on my kitchen table, when a family member turned on the microwave, and having the case open on the TV allowed the microwaves to interfere with the electron gun in the mini picture tube... That was from a PANASONIC Genius 1,000W+ above stove microwave. The TV was a good 25 ft away. I suggest going over to Tech Ingredients UA-cam channel and checking his series on microwave weapons. He has a more scientific explanation on power dissipation and distance with microwave radiation power.
Watch Linus' recent video about his RF chamber. He explained how metal sheets only damp RF radiation to a certain level, but never fully shields it.
It's up to the manufacturer, how thick the metal casing will be. They could make it 2 or 3 mm thick, but then you won't be able to carry it around any more.
Techquickie covering more than just PC and gaming Tech? Nice! Keep it coming!
However how could you miss the opportunity to point out if/how microwaves can mess with Wifi signals? :D
But you forgot that time we used microwaves to thaw and reanimate hamsters! Somebody get Tom Scott in here pronto!
I learned this from Beakman's World Season 1 Ep. 20 "Microwaves, Beakmania and Spiders" on 10 Apr. 1993 and the next day I taught my classmates how it works. wow, it's been 30 years!
Hey, you forgot to mention it resonates at 2.4GHz (speed of light / 2.4GHz = size of the H20 molecule), which is the reason 2.4GHz is unlicensed spectrum and is the reason why WiFi stops working when oven is on.
He didn't forget that, he just didn't got that deep. Every wave resonates at its own frequency.
Water actually resonates somewhere about 10 GHz. But if you would use that frequency, you wouldn't be able to penetrate any moist object. The surface would absolve the full power.
Instead, the microwave is detuned from the resonance frequency so that it can penetrate up to about 10cm into any moist object. At the end, you want your meal to be cooked inside as well.
The wave length is about 12cm, btw. That's not the size of a water molecule.
@@craesh Thank you for explanation. I have to admit I did not dive deep to check that. Guess I have to dust off my old physics books...
A former roomie used to reheat a lot of takeout in the microwave. He'd put a ceramic plate, a takeout meal (in its disposable aluminum container), and a second ceramic plate on top. Metal in the microwave, completely within the profile made by two plates.
He was convinced that it's safe. I wasn't as convinced. Does this accelerate wear and damage on the microwave?
I was just wondering about this randomly in my head😮😅
Thanks for making a video that isn't always about computers and its technology. Even everyday appliances can be counted. I wonder if you do dishwashers next, back in my day, I had a transparent window version before today's version are all blocked due to being noisy.
But don’t pull the door open before the times is stopped. That once caused „random“ spikes in radio-telescopes so that scientists wondered, why they pick up peaks sporadically… someone in the break room just opened the door of the microwave prematurely
Is Riley the new Bill Nye?! They both have great hair, and the smarts of course.
I love LTT and Techquickie but it sounds like you got this functional description from How Stuff Works which is incorrect. The molecules don't spin they shake and the action is not limited to polar hydroxyls. A candle placed in a microwave will light. Oils will heat to the point where they melt plastics. It is the molecular density of what is placed in a microwave field that will determine how much shaking will occur.
Why does the mesh block the waves based on the wavelength and not the amplitude? I can stick long or short things through a chain linked fence, but I can’t stick big things through it. Where am I going wrong in my thought process?
This is the first Riley-Video that doesn't talk about the confusing USB standard - big Like

Finally some useful information in this channel
Lmfao
There's still some leakage, because 2.4Ghz Wi-Fi and especially Bluetooth (2.45Ghz) starts jamming and glitching when close enough to microwave.
my father had a titanium plate in his hand. I remember watching him open the microwave once, saw a flash of blue light, he ripped his hand back and all the hair was burnt off...
Since then I have had one other microwave that did not power down when the door was open, this is due to a faulty switch. Now, whenever I put my hand in a microwave, I start by sticking a fork inside.
this guy has the best presentation skill in the whole LTT industry
xrays and gamma rays have the same range of frequency, the only difference is the way they are produced. Gamma rays are produced when atoms decay while xrays are produced by excited electrons losing energy and going back to stable state
Missed opportunity to use the eric andre meme at 2:49
great info /// How far do the Microwaves Penetrate objects/food?
microwave ovens are why wifi is 2.4ghz - the band was already messy so they let the band be used 'unlicenced'
And 2.4G and 4G and 5g and 6g. All those cell phone wave are in the 2.4 and up wave length. So, you're walking around a big microwave when you step out your door or hold that phone to your head.
If you want to test if your Microwave Oven is leaking, use a pair of BlueTooth headphones near a running microwave. If you start getting stuttering in the audio, that means your Microwave is leaking.
I havent been near a microwave that doesn't cause Bluetooth interference.
yeah I hope this isn't true because if so then I dunno if I've ever been near a safe one.
The sealing is never perfect. A sheet of metal can only damp radiation to a certain level. It's more like a sun glass than a water bucket. It depends on the thickness of the casing of your microwave how much it still radiates.
Watch Linus' recent video about his RF chamber. He briefly explained the dampening of metal sheets.
Nonetheless, BT signals are very sensitive to any kind of interference. A few mW will do the job. In contrast, holding your hand into direct sunlight will already provide you ~10W of IR radiation.
Noice slice of Science of a Tuesday morning!
2.45 ghz... ok, that's why when I was using my previous router with a phone that did not have 5ghz, the signal would drop if I was in the kitchen next to the oven and it was on...
Just worth pointing out, the only kind of microwaves that are dangerous are the kind made by microwave ovens because only that specific frequency resonates with water molecules to heat flesh up.
If you have a wireless headsets the radio frequency is pretty close to microwave and if urs is leaking you can tell by it JAMMING ur headset
I knew some of this, and I learned some more that I didn't know. cool beans! or, warm beans, thanks to my microwave?
i always wait till the microwave is finished beeping
For a second I thought a css framework was sponsoring a microwave video. Weird world.
Here's an experiment you can try: put your phone inside a microwave oven that is turned off, then try calling to it (but never turn on the microwave oven with the cell phone inside, because it'll definitely get fried)
In theory, it shouldn't start ringing, because it's in a Faraday cage
This is why I want to find a big used microwave for my radio experiments. As I don't have the money that LTT have to build a real EMI chamber.
It made me happy.
Please do a video on why MUX switches are needed and why they are not just integrate into the integrated GPU.
Random information I never really thought about until now and now my curiosity has been sated. Good thing Bethesda doesn't make Microwaves ovens. I'd hate to see the result of a bugged Microwave oven.
I can't believe it's the first time I was detailed of how microwaves works.
Elephants are actually afraid of mice for Mythbusters. Tested it. 3:02
thanks!
Damn, my Radium, I thought I was safeeeeee…….
Can’t wait for the Air fryer episode
