Unless you happen to have a specialized ice machine in your home, it is practically guaranteed that the ice your freezer makes is of the cloudy variety. A popular and well known trick to making clear(er) ice is to either boil the water first or use distilled water. However, even doing this won’t guarantee the kind of perfectly clear ice you’d find in a high-end bar or restaurant. This is because how clear ice is, is only partially dependent on the purity of the water you use, meaning even if you managed to procure the tears of a Saint and pass them through the world’s best water filter, you’d still likely end up with ice that was a little cloudy.

*This is a question I never knew I wanted an answer to*
OOoooo Hello Culture, hello Crash, 2 things, firstly would it be possible you can do an episode on the Battle for Itter Castle? And secondly, don't worry crash, only 3 months to go!
I LOVE YOU CULTURE CRUSH!!!!!!!!!!!!!!!!!!!!!!!!!
That's the best kind of question.
Lord Kitchener Oooooo Simple History wasn't enough
CultureCrash yeah
I have some ball ice molds. A couple days ago, I was looking at their payload in the freezer and I thought, "Wow! For some reason the ice in there is really clear!"
And then I realized it was just liquid water and my freezer was broken.
Do a video on: Are pets called pets because we pet them, or do we call it petting because of we do it to pets?
James Fleming
Asking the real questions
Pure ice for sculptures is frozen from the bottom up. The top is stirred to keep particles suspended and the freezing starts at the bottom and works up to the top with the very top water being discarded. This keep bubbles and particles out of the frozen bottom water.
Physically freezing will always start at the top
I'd love to see a video on "How Watermelons Were Turned From Bitter Water Storage Pods to Tasty Fruit"
"...looks like someone crapped 1/2 a cloud into your freezer ..."!!! OMG, SO funny!!!
This answered another question I had lol. I use bottles water to freeze and use as icepacks, and I added some food dye to each bottle just so they look a little nicer, but whenever they're frozen the colour freezes in the middle creating like a core of colour surrounded by mostly clear ice. It looks epic but I've always wondered why that is
Depending on the make of the dye, it has a lower freezing temperature than water. The water freezes at the surface of the bottle first and causes the dye to move closer and closer to the center.
I have a question. Why do we have accents? Even people who lived almost their entire lives in a country, they can't fully get rid of an accent. Why is that?
There are some language specific types of "noises" that are specific to that language. For example the 'th' in the english language is not found in the german language.
It is a bit more complex than that because its not actually the 'th' but a sound in the 'th' that is produced with a specific arrangement of tongue, mouth and all the other parts involved in speaking. This configuration of body parts is not used in any 'noise' needed for the german language, therefore no one who only speaks german ever learned them.
And there is a time frame in which you need to learn to make these noises, (I think is was up to the age of 8) otherwise you will never fully learn how to make them properly.
I have always been able to adapt to the local accent in my area. And yes I did live in Brazil for a time and by the time I was going to come home to the United States, most people could not tell that I was not a native of Brazil. I personally feel that some of the accents people keep is either because they do not want to lose the accent or they are too lazy to work on how they speak.
Calcium is added to water to make it more basic to lower the likelihood of corroding the metal pipes you get your water from.
Next video: Why does Simon have his head upside down?
I don't understand what this comment means O_o
stiimuli maybe something to do with the shaved head and having a beard. That's my best guess.
His chin has more beard than his head has hair. Other people has the opposite. Therefor the joke means that...ah never mind.
Simon's head is for real upside down. If you can't see it, then it means your head is also upside down.
Simon vs VSauce Michael
I thought that I was watching Vsauce for a second.
Similar hairstyle indeed
CTGAMER X but what is "watching"
*Spoopy music*
This ain't RUclips red. Simon is an OG for a reason.
Looks like smart people telling us interesting facts on youtube require a balding head. Examples: Simon here, Michael from VSauce, Adam Savage from Tested.
Faizal F Here's an interesting fact for you: Water itself isn't electrically conductive.
By the way, I'm not bald. :)
I love cloudy ice. Much softer when I chew it. How do I ensure the entire cube is always cloudy
For the best ice cubes at home I would suggest the following:
1. Use distilled water and boil it before use to degas it. Pour it while still warm.
2. Use disposable ice cube bags which are available at the dollar store. These bags will keep out air while the cubes freeze.
3. Limit the time before discarding the ice to around 5 days.
Or you could just use tap water in a small cooler with the lid off. The impurities freeze last so they only form in the bottom of the cooler and you can just remove the cooler before that happens for a nice block of clear ice that you can carve up.
"Best" Ice cubes??? I bet you're a fun person to be around...
Are you related to Sheldon Cooper?
Yes, this is the best and most reliable to get clear ice. I make one large block per week and carve it up into cubes and sticks.
Ridiculous. Tap water works just fine. But you're doing it wrong.
I mostly use condensed tears from kittens for ice cubes.
Well seriously, I had been wondering why ice cubes were cloudy.
I watched a video about a bartender who makes clear ice cubes it is a lot of work but in the fancy bars people love the clear ice cubes, I tried making my own by freezing a bucket of water in the freezer with aluminum foil wrapped around it and two towels underneath to simulate how ice freezes in nature the bottom being the last. and I get about 3 inches of clear ice, but I need a saw with bigger teeth to cut it smaller tooth saw gets ice in between teeth making cutting useless as it just slides ice on ice
Simon Whistler - Answering the important questions.
*REAL* Questions
NECESSARY questions
Fun fact: You can make clear ice at home by using directional freezing. Fill a small cooler with water and put it in the freezer with the top off. The impurities freeze out in the bottom allowing you to cut or melt that part off and you can then cut up the remaining clear ice into cubes. The channel Cocktail Chemistry has a couple of videos demonstrating this and this method is probably the most reliable way of making large amounts of clear ice.

Thank you Simon.
Thanks I always wondered about this.
Making clear Ice is on my bucket list.
Water is also densest at 4 deg. C. So the clear ice will form at the top first and the heavier water with impurities will sink to the bottom then freeze.
If you want to make your own clear ice take a cooler and fill it with boiled or distilled water, the insulation in the cooler makes it so the water freezes from the top down collecting all the impurities at the bottom
You can make clear ice by attaching a small vibrating motor to the ice tray. You can make the motor vibrate by attaching something to one side of the shaft or attaching an offset cam. The motor can be very small, 2 or 3 mm across and a single battery. Works every time, you explain how.
Hey this is a great video!!! I love your channel and I learn so much!!! It reminds me of another channel VCG Construction!
The clearest ice I've ever seen was glacier ice in Alaska
I've recently been making clear ice for my home bar. Freeze a slab in an open cooler in the freezer so the impurities are pushed to the bottom unfrozen water.
I've also heard/read that if said freezing device delivers a gentle shake it furthers clearing, largely due to those gases escaping the water "lattice" which clouds ice.
Ice that Is frozen from the bottom up will push all minerals to the surface. This can then be scraped off and you’re left with a pure surface. Very important in curling ice.
I guess I’m not the only person with this random question 😮
Thanks I appreciate you for being so informed about these offbeat topics
Also, Ice machines tend to freeze the water from 5 sides, with coolant in the tray actually providing most of the cooling, leaving the top unfrozen. That's why ice machine "cubes" have one side with a divot. That was the top side that didn't freeze, allowing any trapped air bubbles to get released.
Thank you for making this clear 😊 very cool indeed 😎
To be fair clear ice is a great indicator that the ice okay to use in countries with lack of tap water sanitation since people will boil the water first before throwing it into the freezer. I knew because I used to get typhus once after drinking beverage with cloudy ice. 2 weeks of brutal diarrhea later, I check every ice given to me everytime I eat outside.
Great explanation! I have indeed wondered this. Thank you Simon.
Nice job, as always. (I'm getting hooked on this channel)
1:23
Those are intermolecular bonds.
Interestingly the science of crystallization is very important in biophysics, electronics and other areas
you are asking and answering the important questions.
My water is horrible, so I got some reusable able ice cubes. Little plastic bubbles you can freeze and put in a glass. They don't water down your drink either.
Umm, heating doesn't get rid of the impurities you mentioned. Heating gets rid of dissolved gasses since water can dissolve less, not more, gas as it gets hotter. (Something fish owners are very familiar with.) You boil the water to drive off gases so they don't instead come out of solution during the freezing process.
Well this explains why the Safeway ice is Diamond clear while my fridge Ice is very cloudy
Can you do a video describing why hot tea tastes more bitter or rich than iced tea? I don't know if it happens to all types of tea, but peony white and jasmine tea definitely taste stronger hot and lighter when iced.
Hello Simon, as you research already about the topic, I would like you to answer me this doubt please. The particles that appears in the water of my fridge might be calcium and other minerals as well?. I thought the water line was dirty and cleaned it with white vinegar but still the particles are present. You see, were I live we use bottle water that is connected to the fridge not the water line as in some countries. I would appreciate your time. Thanks
That thumbnail is on point, give that guy a raise!
Was legit about to ask you this yesterday.
The amount of lime, fluoride, etc, in tap water doesn't have squat to do with cloudy ice cubes. Distilled water doesn't freeze any clearer than tap water. You got it right at the end, but lime and fluoride in one ice water worth of water is barely enough to leave a perceivable trade on a clear piece of glass.
Simon, making the obscure transparent
I really liked the analogy's used today
First Blood's original closing scene had John Rambo shooting himself in the head once the Army caught up with him. It didn't test well with audiences so they shot the canonical scene post completion.
Which still would have been a great ending really.
Also, the role was offered to Dustin Hoffman first but he thought Rambo was too mental (rather than vulnerable), wanted the writers to dial it down but they wouldn't, and Hoffman declined the leading role.
In Flint, MI they have chocolate water ice cubes, heavily fortified with lead to help with the hiatus of brain development.
Yes my question has been answered
So basically, icicle formation. Literally a very cool video!
Do you have a video on if humans only consume distilled water, because I've been led to believe that if we were we would all die because of lack of electrolytes in distilled water but I'm not really sure I'm not a water expert
You're on the right path. You won't die necessarily from a lack of electrolytes in the water as you can gain electrolytes elsewhere, but you would die due to there being no other large molecules/impurities in the water to slow the pure H2O from entering into your body's cells. This rush of water will lyse the cell, killing it. Also, by adding just pure H2O, you create a hypotonic solution in your blood, which pulls nutrients/ions out of your cells to help restore equilibrium. Lose too much of these precious molecules needed perform adequate cellular function, and your cells will quit working and probably die, leading tissue death, then organ failure, and then eventually to you overall dying as well.
There are a lot of pseudoscience arguments out there to not drink distilled water that sound convincing. Until you look at the actual numbers, and use some common sense and logic. The short answer is that distilled water is perfectly safe to drink. It doesn't suddenly become toxic when it's distilled. We get the vast majority of our minerals from food, and the mineral content of water has very little bearing on our overall nutrition.
SpiritHawk7 - You use a lot of sciencey words to sound convincing, but your statements make no sense. I really resent people spreading misinformation like this.
First, to the argument saying that pure water creates a "hypotonic solution in your blood which pulls out nutrients and ions" -
"Hypotonic" just means that it has less minerals (acting as electrolytes) in it than your cells do. So all drinking water is "hypotonic", it needs to be for it to carry out the function that water is supposed to - dissolving and transporting things. If you want to drink something that isn't hypotonic, then drink blood, or seawater - actually don't do that, it'll make you sick for obvious reasons.
Second, the statement "Lose too much of these precious molecules needed perform adequate cellular function, and your cells will quit working and probably die" is really misleading.
Yes, if you try to live on only water (any kind of drinking water), you'll eventually die from it. But we get the vast majority of our minerals from food, and the mineral content of water has very little bearing on our overall nutrition. For drinking water to kill you, it doesn't matter if it's spring water or distilled, drinking enough water to dilute your blood to the point of dying takes a lot of water.
[Figures taken from "Comparison of the Mineral Content of Tap Water and Bottled Waters" - Pub Med ID : PMC1495189]
The Total Dissolved Solids in drinking water are less than 500mg per liter, with an average of 300mg.
On the high end, tap water from groundwater in North America has 48mg calcium, 12mg magnesium, and 83mg sodium.
On the low end, average bottled spring water has 6mg calcium, 3mg magnesium, and 2mg sodium.
The rest of the dissolved solids are mostly dirt and heavy metals.
Recommended daily intake for these minerals is : Calcium 1000mg, Magnesium 420mg, and Sodium 1500mg.
It should be obvious from these numbers just how little mineral content we get from water.
Last, the notion that "large molecules and impurities slow the water from entering your cells" and the "rush of water will kill the cell". I don't even know where to start. Impurities have nothing to do with how quickly water is absorbed into the body. Cells have ion pumps built into their membranes to maintain osmotic pressure.
Really, if bottled water is just fine, but distilled water is somehow "toxic", then going by your logic all you'd need to make a liter of distilled water "safe" is to sprinkle in 10mg of salts. That's the only difference between the two, after all.
I said "sciencey" words because the topic is biomedical science, an area of study which I have a Bachelors degree in. FYI, my post was in laymans terms for non-science people to understand it. I feel like you need to actually take cellular biology and chemistry classes first rather than just post a bunch of random information, such as daily recommended values, that has nothing to do with the topic, or simply dismiss what I have to say because you don't fully understand it correctly.
Water (H2O) does not use Ion channels, such as Ca2+, Na2+, Mg2+, and K+, etc., in order to enter or exit the cell. Ion channels are very specific for only those small specific atoms, not larger molecules that cannot fit. H20 can permeate through the cellular membrane while using facilitated water transport channels called "aquaporins" and other pores that can fit larger molecules through the process of general osmosis. There are larger pores that let glucose and other polysaccharids in, etc.., thus where impurities come into play.
You stated "Cells have ion pumps built into their membranes to maintain osmotic pressure." yet you completely overlook what I mentioned about tonic equilibrium. Cells function best in ideal conditions within a small range of tolerable hypotonic and hypertonic solutions. The cell's internal cytoplasmic tonicity responds to external stimuli, as the body is a closed system. Too much solutes outside, and the cell will release H20. Too little solutes outside the cell, and the cell will intake H20. DI water is just H2O added into the bloodstream, no other ions, which interferes with osmotic pressure, causing cells to absorb water. Cells will continue to absorb water and lyse while tying to reestablish tonic balance (the cell doesn't say "oh, I'm already full of water and stop" if balance is still not re-established by that point.) Also, as I said in my other post, if there aren't enough ions outside to replenish what is being used inside, normal cellular function will be interfered with and be diminished.
Since you brought up daily values, general purified/filtered drinking water and bottle water, are also not good for you to drink as they don't meet recommended standards either. DI water is just on a worse level than them as it strips ALL the ions from the water. So, you should not get into a habit of drinking it, because as I mentioned in my other post, and you mentioned, water isn't a large source of nutritional value. The point I was making is that non-DI water isn't as readily absorbed as fast into the body as just pure water that basically just floods straight into the blood stream. Also, regardless of water being DI or not, you should not drink tons of water in general as either way you will get water poisoning, and you will die. Morbid fact, chugging a gallon of water in basically a single sitting (even over the course of just an hour), will send you to an early grave within a short few hours or less. Many people have died that way because they thought water was harmless and you couldn't have too much of it.
P.s., Adding a few mg of NaCl to DI water still doesn't make it "safe" water to drink either, as there's much more in actual water than just simple salt; you can't survive on a saline solution alone. As you mentioned, you already know drinking salt water isn't good for you either
I said it used those ion channels to maintain osmotic pressure, not that water goes through them. The amount of water drawn into or excreted from a cell depends on the electrolyte concentration, does it not?
"Tonic Equilibrium" is easily maintained when you're pouring a glass of water into a, say, 175lb body that's 60% water. That's like 13 gallons of (isotonic) water, compared to 12oz being added in.
Regardless of the type of water, for it to disrupt your cells to the point of death you would have to drink massive amounts of it very quickly. These aren't lab conditions where you're putting a blood cell into pure water - along the way in the process of drinking, it's picking up all sorts of stuff. The saliva, mucus, food, along with everything in your bloodstream. As if that even mattered. No one sane is trying to live off of water anyway.
Saying it "strips all the ions from the water" is disingenuous. It will pull substances until it reaches an isotonic state with your body, the same as spring water or well water. The difference between distilled and spring water is what, 100mg of electrolytes per liter? (Oh, and the 200mg of dirt and heavy metals that are somehow supposed to do something) Drinking water absorbs ions regardless of being distilled, and the difference is negligible.
An isotonic solution is 9% dissolved material. Unless you're drinking water with the equivalent of 50g sugar and 2g salts per liter, you're drinking a hypotonic solution.
The average amount of water a person consumes in a sitting is nowhere near enough to disrupt the concentration of electrolytes in your blood, or to kill cells. You said yourself describing hyponatraemia "chugging a gallon of water in a single sitting will kill you".
That's why I mentioned the DV for electrolytes - to show the magnitude of difference between what the body deals with and what you're talking about.
You can eat a meal with 500mg of sodium, or drink a glass of juice with 800mg of potassium and be fine. So cells aren't that sensitive to slightly hypertonic blood, but slightly hypotonic blood will kill cells? Again, your argument makes no sense.
You keep saying it's the time it takes the body to absorb the water that makes the difference. So what's the difference in the time between distilled and tap water? Can you point me toward any science or medical papers?
PS - I said "salts" as in "electrolytes" (without having to type out "electrolytes" every time). Not "salt" as in NaCl. And I'm not saying you can survive on a saline solution alone, or even a solution that had all the electrolytes in it. (Not like putting 10 or 100mg of salts into a liter of water is going to suddenly turn it into seawater, either) I'm saying people get their minerals / electrolytes / ions primarily from food, and the amount of difference between distilled and regular water is negligible.
My new goal in the bucket list is to make a perfect ice cube, chemically and geometrically too.....
So...that's why hot tap water is a little "white" while the cold water is clear?
My hypothesis is air pockets.
Just about every Starbucks has perfectly clear ice because they use a reverse osmosis filter. I don't know how much the whole system cost but I know one filter cost $6,000
James Engles
I grew up with a house reverse osmosis system, our ice is less cloudy but still has bubbles. Starbucks probably has the commercial icemakers like Simon mentioned.
(You can get cheap RO filters btw.)
Fun Fact as a bartender who makes her ice at a restaurant we don't even use a filter straight from the sink and into a Regular cooler than in the freezer..then we shave it..just watch tipsy bartender he explains it perfectly
There are a few videos on RUclips about making clear ice. I tried it, and it works, but it's a bit more hassle than I want to deal with on a regular basis. Maybe I'll do it for a special occasion.
I work at Starbucks and I noticed this and figure that it had something to do with the temperature of the ice because fresher ice was always more clear then the ice that has been sitting together for some time
Yes But aqueous creatures prefer cold water because they are more soluble in it..... This whole thing that some stuff are more soluble when water is warm and some when water is cooler really fascinates me
Suggestion, Today day I found out about the Battle for Castle Itter, Dubbed the strangest battle of World War Two.
Amazing.
Not impurities. Its the physics of water. Freezing water EXPANDS. When the water in the center of the ice becomes frozen it has no room to expand into and causes microfractures that cause cloudiness.
Since most common chemicals and impurities tap water are measured in the parts per million or billion range, I doubt they have any significant effect on the cloudiness of the ice cubes. I believe the overwhelming reason would be dissolved oxygen (DO) in the water. Colder water holds more DO than warmer water. Hence, boiling it tends to release the DO found in the water to the atmosphere.
Timothy Baker there was also no mention that commercial ice machines produce clear ice cubes by the method of freezing moving water.
DP T
I'm assuming you meant boiling. They may incorporate other methods of making ice that drives off DO.
No not boiling commerical ice maker circulate water over the evaporator to produce clear ice.
I always wonder why some people pronounce the word "distributed" with emphasis on the first syllable instead of the second syllable as is said around the 2:05 mark
I'm lucky. We have some of the best water in America and I use a water filter. My cubes are almost always clear.
Also, one directional freezing is a way to yield clear ice
My mini-fridge makes perfectly clear ice for some reason and I just get the water from my bathroom sink, but I have no idea why
What kind of mini fridge do you have?
@@Ark8ngel I moved and don't have it anymore so I have no idea. If I find a picture, I'll let you know
Whistle for us Simon!
I’m I the only one that prefers the ice cloudy? 🤤
today was a good day
VSauce4 Confirmed?
Why do we refer to ships as female?
nitestryker7
Tradition! From the sailing days
When ya sweat and bleed to keep
her floating in the midst of the terrible ocean.
Seemingly everything has a female name. Mustve been a bigger percentage of men at sea than women....and theyre all horny and lonely.
Because it contain so many seamen in it.
To remind us sea-ward fools who've been out too long to be civilized, that you should treat the ship and her controls the same way you treat a lady. You must be steady and consistent, and keep a gently firm hand on what you're doing... especially the wheel or tiller...
You can always tell a newb' at the tiller. Just look at his (or her) wake. As the sea and ship rock back and forth, the compass rolls inside it's chamber, and the newb' is constantly moving around to keep at the heading... That sends the rudder(s) back and forth and rocks the ship even more... so while the ride gets rougher than hell, and pots fall from the galley walls... behind the ship you'll see the wretched curves and wash disturbing everything for hundreds of feet in every direction...
...But a seasoned "salt" at the tiller, calms down and holds steady. A casual eye to compass or repeater, and the heading stays ahead at full. In the wake of the vessel is but a clean line, nearly as straight as an arrow for miles.
...and finally, yes... you can track ships at sea for miles by their wake. As they cut through even the middle of the oceans they disturb the planktons and other little creatures, and the water surface shows it for hours after a ship has passed. :o)
Fun Fact: Russian ships are called "he".
I eat Ice cubes all the time.
*And I never knew.*
Do you take a little coffee (or tea) with your sugar?
I'd rather see the white color in the ice rather than see any insects frozen in it.
I once had someone take my pet fish, a Paradisefish, and put it and it's container in the freezer and froze it solid. I was not happy about it...
Everyone, please watch my tiny nature videos. There is no talking in them. Shhh!
Zom Bee Nature
That's an amazingly large video collection you have! Do you use a lot of searchword tags so people can find them?
I have never wondered this but, neat?
And he still didn't explain why ice machine ice is clear and freezer ice is cloudy, but I already knew the answer, any refrigeration man knows the answer.
What i'd like to know then, is why does normal tap water taste like normal tap water, while tap water which has been frozen to ice, and then melted again, taste metallic.
stop storing your scrap metal in the freezer
Ha ha very funny. but seriously though.
I can taste a difference between normal water and water that has been frozen and then melted again.
Quick ? Ive ask others but cant sesm to answer 100 %. I know i can boil water to purify it but when i freeze my tap water does that purify it like boiling it ? I know plastic is horrible for the environment & us but sometimes I poor my tap water into plastic bottles to freeze them does this help me or am i wasting my time doing this ?? Thanks if u can help !?!
Imagine Antarctica as clear ice
I dont want to and you cant make me
Would one benefit or suffer if someone made a point of drinking the still liquid part of the center of the ice cube? My sister used to do this when we were kids and actually developed something of an annoying habit for a year or so of doing that.
Broken Eyes As long as it's just regular minerals in there...why would it be harmful? I like to eat half frozen eyescubes, too, crunchcrunchcrunch 😊
💚
What causes razor burn and how to prevent it?
You aged pretty well XD!
Do a video on why or what happens to people when they passed out from being punched. I don't understand what causes this, seems like a protective function...still seems odd.
If you want incredibly pure ice crystals, why not use the same process they use to make fantastically pure silicon for semiconductors - only at a much lower temperature? en.wikipedia.org/wiki/Czochralski_process
Distilled nor boiled water work lol
Why did I find this super interesting??
perhaps because:
1) Its a familiar issue most of us have noticed
2) The reasons for the issue are rather easy to explain and understand without complicated maths or long stories
3) Its also rather easy to test the solutions that were explained
4) Clear ice cubes are pretty =)
so... much like how some of Simons shirts fit and some don't?
not seen daven in a while...
interesting video too, thought i knew the answer but apparently not
Yes! I've always wanted to know the cure for cancer and the meaning of life but THIS WILL SUFFICE!
Ok i have a question why does receipt paper or plastic bag work to swipe a credit card
Is there a background music?
Interesting, I was afraid my freezer was poisoning my Ice with freon. My next question is why does my computer not accept the word 'freon' as a real word?
this damn vsauce lookalike tricked me!
When you need to hit that minimum word quota to stretch out the length of your youtube video.
But what are the fancy people doing to remove the impurities that distilled and boiling water can't? Why do they use to make those clear cubes?
