There’s a rather persistent idea that “reboiling” water (i.e. boiling water two or more times and allowing it to cool in-between) while making a cup of tea is potentially harmful to your health, with some going so far as stating that regularly doing this even drastically increases your chances of getting cancer. The general reasoning behind why this is purportedly the case goes something like this:

This is on par with “ I don’t use a microwave because it changes the genetic make up of my food”.
It’s energetic (not genetic) makeup that gets changed - in the microwave
especially the natural (liquid crystalline) water molecules in your food become distorted and disconnected.
The liquid crystals are conveyors of pranic quantum energy /cosmic energy / life force. Technological Radiation dissonant with life energies is detrimental/ taxing
to each’s natural vitality.
Namaste
@@thomaxtube now I have heard both.
@@thomaxtube That's a load of bullshit
You can't "distort" or "disconnect" a water molecule. That's not how molecules work.
@@thomaxtube No. I'm going to stop you right there, no. The "energetic makeup" doesn't get changed. Microwaves are a low energy wave in the light spectrum. They cause the molecules to vibrate, this creates heat, and as such, warms up your food. Or any other object placed into the microwave. It doesn't distort or disconnect the water molecules. That would blow up your kitchen and your entire neighborhood. As for the rest of the word salad you threw in there, most of those words aren't even things.
@@thomaxtube You are so wrong on so many levels. The sun produces light. Everything from UV (high end) to low IR (low end) The oceans, lakes, trees, and people are exposed to microwaves every time they step outside. None of what you said is even true, or makes any sense what so ever. And everyone is now dumber for having listened to it. You are awarded zero points, and may G_d have mercy on your soul.
“Twice balled water.” Now that’s a tea bag.

Simon should have just answered this question by laughing in your face for 5 minutes, then catching his breath and saying no
actually there is a very good explanation why you shouldn't boil water twice and it's the same reason you should only drink tap water after you let 1 L run through before drinking it. it's about the heavy metals in the water. this is very serious. I have just recently seen test results from tap water and the longer water sits in a metal enclosure the more metals it contains. for a tap it was very simple after turning on the tap the first water coming out has incredibly high concentrations of heavy metals and is not safe to drink, that contamination then decreases exponentially and after the first liter had passed the concentration was low and safe to drink. makes absolute sense to me that boiling water in a metal container and especially boiling water twice increases the problem. also in many parts of the word the mineral concentration in the water is very high and hard water leads to galvanic corrosion which only increases the high metal concentration. most of europe has incredible high mineral concentrations. another consideration is that many people use cheap water boilers made of plastic. most water boilers you can buy have a plastic water container. only the more expensive ones use metal. but the plastic has it's own problems. when you boil water in plastic is gets contaminated with all sorts of unhealthy stuff like BPA. all in all I would never boil water twice. turn on the tap, let 1 L run through and boil the fresh water in a metal water boiler or pot. that reduces most of these problems down to a manageable safe level.
Mar yes, but the container you’re boiling it ibis not made out of heavy metals, it’s made out of steel, aluminum, or glass, hopefully. If you have a lead kettle, I’d recommend not having a lead kettle.
@@swunt10 Still the difference between boiling the water once vs twice is very negligible. Just watch the video and you will see they agree
@@swunt10 I'm gonna need to see a source on that...
@@Boomchacle would you look up the different definitions of what heavy metals are please.. the most useful definition is every metal over 5g/cm³ is called heavy metal which includes the steel you mentioned. especially aluminium is not safe to consume even though it doesn't count as a heavy metal. also you don't seem to know that most pots and kettles and taps are made of alloys and they all include a huge variety of different metals or do you think stainless steel is just iron and carbon? also I don't think there are glass boilers or pots. that would be new.
I did a calculation on that some time ago. In the Netherlands you'd need to boil your kettle dry (yes dry) about 7000 times to get to a theoretical concentration of any where close to what the EU considers a carcinogenic risk.
Seriously impressive 😊
It sounds like the kind of thing I'd do. But I got tired of cleaning mineral deposits from my kettle, so now we only use filtered water. 😁
@@CynBH oh i found the solution to that. get a black kettle. youll never see the deposits
@@wendywright4659 Funny story. Several years ago, my husband asked what I wanted for Christmas. I said a new electric kettle. But I wanted a pretty stainless steel one because the kids were all old enough to not burn themselves and we didn't need the ugly plastic "cool touch" kettle anymore. Guess who burned their arm in the first week? 🙄 I seriously should know better than to tempt the universe with a smug statement like that! 🤣
Hmm, I better get started boiling...

I, too dislike how UA-cam incentivizes creating longer rather than quality content, and steers creators' instincts away from adhering to audience preferences a bit more on the pulse. I would've loved a "this is where we talk about what you're actually here for" and a "now we're back to interesting things about boiling water and metabolism", possibly with timed links.

3. Pour aforementioned coffee into coffee maker's water reservoir
4. Press Brew
5. Pour cup of damn.
6. Drink
7. Exclaim, "DAMN!"
Damn
DAMN!
I like to mix my coffee with my coffee
Yo dawg I heard you like coffee so I put coffee on your coffee
Why would that work? Don't coffee makers steam the water? The reservoir would just be left with coffee sludge.
I love how this video goes from about boiling water to the non-ending debate about how to make tea!
Builders Tea for the win.
As a chemist, I thoroughly approve of this video.
Finally someone mentioned chemistry and not whether it's ok to state "no" for 15min.
While impurities were mentioned, the only elements elaborated on are iron, nickel and lead, not one word about calcium in the whole video. In my experience most everyone I know can taste higher levels of calcium or,indeed, calcium carbonate in the water when boiled multiple times, so are there areas where there is none of it present in tap water, and thus the makers of the video were not aware of the influence - or does everyone else here filter it out completely anyway?
@@borisos9832
You might like to read up on something called Hard Water.
I recommend penta-boiling. The first boil kills bacteria. Second boil leaches iron from the pot. Third boil incorporates settling asbestos dust. Fourth boil re-introduces bacteria. Fifth boil melts plastic lining of boiling can.

@@CrusaderSports250 A bit late to the party on this one, but the majority of americans don't use a kettle to make coffee. A coffee maker (either full pot or single cup) is as common in american kitchens as a toaster, and about as cheap and easy to buy in nearly every store, and the pre-ground coffee for use in these machines is, similarly, widely avaliable everywhere. In fact, using a kettle (with, say, a french press) to make coffee in the US is rare not because it makes worse coffee (most would tell you the machine coffee is actually worse) but because using the machines is much more convenient.
@@michaelmusker7818 kettles are definitely the way to go over here, in fact more common than a toaster, and as far as a French press is concerned, is that some kind of exercise position?☺, but jokes aside I can't think of anyone I know who has a coffee machine, but they all have at least one kettle, its also a quick way to get boiling water for cooking, and tea of course☺☺.
A friend told me that re-boiling the kettle boils all of the oxygen out of it. I’m a scientist, so I told her that would leave the kettle full of hydrogen. She didn’t understand. 🤣
This is such a midwit take. She was clearly talking about dissolved oxygen. She's partially right but it also doesn't matter. Apparently that went right over your head as you tried to dunk on her about the literal meaning of her statement with an elementary understanding of chemical composition.
THE TRUTH:
Boiling water twice can result in some traces of Dihydrogen Monoxide
Are you serious? Isn't that the chemical used in nuclear power plants?
Lee Klinedinst it is indeed, they use it to turn the turbines. If you live close enough to one it sometimes falls out of the sky. The worst kind is the really cold dihydrogen monoxide. It can literally freeze in the sky and fall to the ground covering everything in this white mess.
Oh good heavens no! Why is this allowed!? Oh the horror! I've heard tales of people drowning in such an ungodly substance
SolarOtaku I know, it’s awful really. It’s gotten that bad that around 70% of the entire planet has now been contaminated by the stuff. Nobody ever thinks of the poor dolphins 😔

Question. I have a small metal kettle that holds 2 cups of tea. I just ually drink one cup and save the rest for the next day. I will pour the day old tea into my cup and heat in the microwave. How does saving the tea for a day affect the tea?

You don't boil any of those.
I litterally call them vegetables tea or fermented leaves soups aka I don't like either of them.

I've noticed that when I reheat my tea in the microwave more than once it does start to taste bad. Once I tested doing it four times in a row, letting it cool down and reheating, and had to spit it out.

I used to work with a bloke who would make his tea, in the mess room, which was a bit of a distance from where he drank it at his work station. He always boiled the water for longer, he said, because he didn't want it to be cold when he returned to where he worked. In short, he thought that the water would get hotter the longer he "cooked" it for. The worrying thing was, he worked in a power station!

I have just recently seen test results from tap water and the longer water sits in a metal enclosure the more metals it contains. for a tap it was very simple after turning on the tap the first water coming out has incredibly high concentrations of heavy metals and is not safe to drink, that contamination the decreases exponentially and after the first liter had passed the concentration was low and safe to drink. makes absolute sense to me that boiling water in a metal container and especially boiling water twice creases the problem. also in many parts of the word the mineral concentration in the water is very high and hard water leads to galvanic corrosion which only increases the high metal concentration. most of europe has incredible high mineral concentrations. americans don't even understand the problem since they have very soft water. another consideration is that many people use cheap water boilers made of plastic. most water boilers you can buy have a plastic water container. only the more expensive ones use metal. but the plastic has it's own problems. when you boil water in plastic is gets contaminated with all sorts of unhealthy stuff like BPA. all in all I would never boil water twice. turn on the tap, let 1 L run through and boil the fresh water in a metal water boiler or pot. that reduces most of these problems down to a manageable safe level.
@@swunt10 Americans have soft water? Have you heard of limestone caves? I lived in a city that was surrounded by them, all underground. Where do you think our water came from? Not the contaminated river, no. It came from underground, after passing through enough minerals to build a damn skeleton. Seriously, it caused plumbing nightmares everywhere. People made a killing off of water softeners and limescale removers.
Alexander Mills here in America we have all the water. Hard, soft and everything in between. In Madison WI, for example, there is an aquifer that actually feeds the city. But where the water is stored is in magnesium. This makes the water very dense and very hard. We have water softeners so it doesn’t clog the pipes and our faucets.
I have literally never heard of this lol
Same.

Consider yourself lucky. This is essentially a revised version of the myth that microwaves make your food carcinogenic or otherwise toxic, including water, made popular after a "science" experiment in a UA-cam video showing that microwaved water killed a plant when watered with it as opposed to one watered straight from the tap. Strange how that is when the fluoride in the water is supposed to be super deadly already......
You are not from tea drinking country
It's a slow week I'm guessing
Why have I never heard this? I thought I knew most anxiety ridden fears...

This is the first time I ever saw a whole video devoted too feeding a troll.
You must be a noob
@@cheezburgrproduction The title of this one made me laugh so much I had to watch.
You haven't seen the "Why do I have butt hair" video on scishow? That was aimed at their most persistent troll.
@@Primalxbeast Oh, I"m so em-bare assed. I am a n00b after all. That was a dish of troll food, and yeah... I did watch the "why is there hair around my anus" Sci-Show. So I'm wrong, I've defo seen one before and now I amend my first statement: *"This is probably only the second time I've seen a whole video devoted to feeding a troll."*

I never eat the crunchy leftovers from over boiled water.
How do you know they are crunchy then?
If your drink your water scalding hot it kills cancer and cooks your goose.
If this was an actual question that was asked, I despair for humanity.
The one I kept hearing for a while was that reboiling the water removes the oxygen atoms (probably because of the bubbles), so it turns out you can make deuterium in your kettle.
You think that we drink H2O. That's so cute.
@@DurgaswaroopPerla You think I'm cute?! ☺ If only patronising comment jerks were my type. ♥
This is the first time I've ever watched Simon explain something and come away feeling like I've listened to a Monsanto corporate lawyer turned congressman avoid answering a simple question directly.
Simon is, in actual fact, the FBI.

Simon is from the future.
Actually Simon is secretly a lizard man working as a ml6 mole working for the fbi and is in fact part of the cia

That opening quote really threw me for a loop as to how anyone would believe what they were saying.
From this video I learned that I am a tea barbarian. I gave up coffee and replaced it with tea... but I never knew so much about the intricacies and art associated with tea. I had a clue but I had no idea how serious of a business tea can be. Thank you for opening my eyes once again.
Also, how can Orwell have considered himself a true tea lover if he ruined the flavour by adding milk into it :-P
Because it tastes nicer with milk, tea without milk is just slightly impure water.
"Filtered through a hobo's sock". Has someone actually tried this ?
There's no better way to filter drinking water.
jimjams20001 Underwear maybe, never a sock! Hahaha
@@Chief2Moon underwear would be a daft choice, whereas a sock has a natural containment structure, maybe we need a video to explore the attributes of using clothing (in both modified and unmodified forms) as filters, with benefits and attributes of each, or maybe not!! 😎.
It's worth noting that leaving water in the kettle, even if you pour it out before reheating, can sometimes make your kettle rust out faster. Better to keep it dry when it's not being used.
/I once saw an episode of some show... a half hour on how to make toast. It was actually brilliant. Did you know that if you use a toaster oven when you pull the door open and it gently sticks at one location partially opened... that's a design feature? There are all sorts of toast... that toast that is crispy on the edge but soft in the middle, but there is also a much crispier, but not burned toast that is more like a cracker. It's really yummy. To make it you leave the door partially open. It lets the moist steam out and the bread ends up much crisper.
Question, what's more important, boiling or temperature. Because water can boil at lower temperature under less atmospheric pressure, and at room temperature in a vacuum. So I'm wondering which is the key item, to boil, or to heat to a certain temperature.
This sounds like an "antivaccer", "flat Earther" type argument...
That's precisely the type of folk that eat this crap up. The type that say "Don't go to the doctor, chew this root instead."
Niklas S look up Varg Vikernes and his view on vaccines. It’s harsh and logical. The flat earth people are actually worse than this too.
@@SteveEchelonanon Here's the history of our medicine.
"I have a sore throat."
2000 BC : "eat this root"
1200 AD : "That root is heathen, say this prayer."
1500 AD : "That prayer is superstition, drink this elixir."
1800 AD : "That elixir is snake oil, Take this pill."
1900 AD : "That pill is ineffective, Take this antibiotic."
2000 AD : "That antibiotic is artificial, Here why don't you eat this root."
One of the bash.org classics.
@@thinkingmachine354 - Harsh. Logical, however, is questionable.
Red Jack what’s questionable about it
I have never ever heard of this, interesting video.
Odd timing on the tea rap I literally went looking for that this morning cos I needed a laugh.
And Daven is a boss "Tea, Earl Grey, Hot"!!!
So Carl smallwood and doc brown name checked in the same video. So good!
I’ve been using a tempered glass electric kettle with LED light at the bottom - and bottled distilled water. I top off the unused water with fresh water each time, and after a year haven’t noticed any cloudy residue or patina inside the kettle.
I don’t consider myself British but this made me feel British

Are you British?
Lethallizard 9 Good
Drink some Yorkshire tea, you are now British
edmund blackadder coc just finished a mug, can confirm it’s the best
Didn’t you cover this already? I remember u covering this
They did, except it was Daven that did it the first time
SciShow covered this in a very similar way. Since I watch "Today I Found Out", UA-cam suggests "SciShow". Perhaps this happened for you recently too
a lot of youtubers are plagializing each other.
@@davidjacobs8558 in this case though, TIFO plagiarized themselves
not the first time they did that
does this apply for food . i was always told not to reheat reheated food
This is very much the sort of response I would give to someone if they had asked me this question. I've been asked before whether I am able to give a straight "yes or no" answer. well....
You Brits are so silly with your ideas on the best way of brewing tea. We Americans have known the objectively best way to make tea.
1.) Take tea
2.) Locate the harbor.
3.) Throw tea into the harbor.
(Optional) 4.) Enjoy a nice cup of coffee instead.
From Boston?
@@arguspanoptes9510
Nope. Never even been.
Right on brother
I am British anyway. I don't need to throw the tea in the harbo(u)r because I much prefer to have coffee
In fact I am off to get one after I am typing this
@
Nah. I'm good. I don't really care where the coffee is from, so long as it hasn't been screwed with and is coffee-flavored coffee. French presses are great, though. Bit of a pain in the ass to use, I prefer drip brew for sheer convenience. Never instant, however. Instant coffee is just terrible. Same goes with percolator brewed coffee.
Where do i find one of these Monks silk robes? 🤔
Well, that's a relief, I was all ready to be worried and regretful. .
Perfect explanation, not everyone is going to be able to digest this!
