I can't believe it took me 10 years to find this video... I just tried it and it totally works... I love physics... currently enjoying a nicely chilled drink thanks to this man...
Great tip if you have company call without prior planning and want to have cold drinks ready when they arrive. You want to be a good host, but you can't be prepared 24/7 for Pop-ins. Thank you for sharing this idea. It will also be especially helpful in my house, because inevitably, even with a full fridge of cold drinks, my kids will want something else.
Adding salt does NOT cause the ice to melt faster. Adding salt to water lowers its freezing point and therefore gives a greater temperature differential between salt water and the can and surrounding air.
Thank you for sharing this. I appreciate it. My local liquor stores often have specials on craft beer. Many times I cannot get there until late in the day. When the specials are on they are not always available cold. So i grab the warm ones. This trick actually helped. For those people trying to feel funny or important by saying just add ice to the drink , it does not work with beer. I understand you want to come on the internet and rip on everything. If you are going to do that, at least use a bit of creativity tinged with some humour. Thanks.
Adding ice to sodas also doesn't really work because you have to add a lot just to cool the drink, and by the time the temps drop enough, too much of the ice has melted, and you're left with a watered down drink.
This method of cooling a drink, helps to explain why we were taught to add rock salt along with the crushed ice, when filling an ice cream freezer. Our parents had both grown up on farms with lots of eggs a whole milk, but did not know the science of why you tried to melt the ice to make it colder. “Shut up and keep cranking.” Finally at seventy three I have the answer.
The reason why he's using salt ice water instead of ice water is because salt solution's freeze point is lower than regular ice water. The temperature of the salt ice water vs non-salt ice water is the same, but the solution has more water in it due to a lower freeze point. The best way to conduct heat is through water in this case and not ice, since ice that surrounds the can still has air and it does not conduct heat as easily as liquid.
I think this is a pretty good tip for when you want to have a really cold drink, but don't want it to be watered down by the ice in just a few minutes. Maybe you have company show up unexpectedly and would like to offer them a cold drink, but there isn't enough ice to fill everyone's glass so you use what you have to cool the cans or bottles this way! It's the same concept as making ice cream, just in a smaller scale. Thanks so much for the idea!
Your video brings back memories of home made ice cream. Neither Mom or Dad could explain why the salt was needed, but it was. A friend that served in the South Pacific with the sea bees in ww2. They cooled beer by wrapping the bottles in gasoline soaked rags, and blew them dry with construction sized air compressor. “Do not try this at home, or around a barbecue
really great, vraiment intéressant ce qu'il rajoute en plus des glaçons c'est du sel de cuisine pour ceux qui ne comprennent pas l'anglais , c'est de refroidir des canettes de soda en 2 min en partant d'une température ambiante de 24 ° C ou /5 ° F. Cool merci de l'info
Make it cool even faster by rotating the can! The rotation causes the drink to move to the outer edges of the can, where the aluminum is in direct contact with the ice. This transfers all the heat from the center of the can to the walls of the can where it is pulled by the ice cubes. Ive cooled a can down in a minute doing this!
what he is saying is correct, when you mix water and salt the freezing point gets much lower, which means you have a very cold liquid. this method is also used to melt snow by pouring salt on ice or snow.
It's actually quite a difference! An even better method would be to use Calcium chloride and spin the can while it's in the bath. If you use 100g of ice and add 143g of CaCl2 you can reach -50°C!
very good trick! I want to add a suggestion. If you want to coll more than one, and you dont have ice cubes, Wrap the can with one or two wet napkins and put it in the freezer! In 15 minutes it will be chill enough to drink it!
Instead of going through all that trouble getting it ready, you can just get a paper towel wet it and wrap it around a can of soda or whatever beverage you prefer. Put it in the freezer for about a good few minutes and viola!
DeliCiousTZM Take a bowl, use water that's like 15 seconds at the longest. then dump in the ice and put your drink in. If you cant manage to do that in about 60 seconds then you should drink your beverage piss warm. cheers.
@@Smartacus420 There's no way to cool anything without something being pre-chilled. For example ice. And if you dont have ice, become an adult and get the ice trays.
I drop it in and drink. Because it's cold. Don't know if there are other kinds of icecubes you use. And it does thin it out of you leave it for half an hour. True, I can live with it, because I got icecubes left for more drinks. Unlike you :D
It'd be interesting to compare icebath with and without salt. Something tells me, salt makes not much difference, if Your aim isn't to freeze the soda solid.
***** It does indeed. It lowers a water melting point couple of degrees, so the drink gets cooled a bit faster. No magic here. My point is this couple degrees (it's around 6 degrees C per 10% NaCl concentration, my guess two tablespoons won't make 10%) does not matter much in cooling the drink. Though it is essential indeed, if You'd like to freeze the liquid. Like when making an ice cream. So the question I asked first place was, how much it'd change the game when cooling with and without salt. Hope Dave would make another vid with an experiment :)
Johannes Hass Indeed. Especially in the end of the process, when difference is smaller. So the importance of salt depends on target temperature. Is it wine or vodka we are cooling :)
***** So why does salt melt the ice? Is it magic? The ice is melting because melting point of salt solution is lower than melting point of a pure water. It is a property of liquid and solid mixture: it stays at the melting point until it all freezes or it all melts. So 330 kJ/kg is an amount of energy ice can absorb melting. But it won't go below it's melting point. And cooling speed is about temperature difference. So if You want to go lower or go faster, You need salt. If Your target is 15C, it makes no difference.
azgarogly His target was 5C, not 15C, for a DIFFERENCE of 19C in only two minutes. Speed is, in fact, the point. The more rapidly you want to induce a change, the more steep the difference needs to be. The salt water was undoubtedly heading for a temp below 0C, since it's freezing/melting point would be below 0C, but it would heat up more slowly the closer to that temperature it's surrounding environment (including the can of whatever) became.
Liquid Nitrogen works really well. I used to pour it right into a cup of soda pop. If I'd had canned soda, I would have dipped the can into it instead though.
For those who wonder why to use salt in this proccess, it just makes it way faster to cool a drink with it, because the salt needs energy to dissolve in the water, and it takes this energy (heat) from the ice cubes, which makes those cubes cool faster and tadaaaa.
This is only part of the mechanism. While salt dissolving is endothermic (it pulls energy in from its surroundings), the main way this works is by lowering the melting/freezing point of ice/water. Otherwise, as the salt dissolves, it would freeze the water; instead, we see the opposite. An easy way to test this would be to have identical bowls with drinks and ice, and make sure all the salt is dissolved thoroughly in one bowl while you mix in the same amount of salt in the other after adding the drink. Have a third ice water bowl with no salt as a control.
I just want my drink and don't want to get a bowl get water in the bowl get two bags of ice and put them in the bowl with a couple tea spoons of salt because I just want to drink my drink and chill I don't want to drink it then wash everything up😂😂😂😂❤️💖love this channel💖❤️
I don't get it. if you have the ice already just get a glass and put the ice in the glass and fill it up with the drink, why do you need to waste all the salt?
blakespower You can use this technique for cooling down soups in bigger kitchens. This is important since the faster you cool down your soup the less chance for spoilage.
Myth busters did an episode freezer vs fridge. 1 hour in the freezer and 9 hours in the fridge normally, but the biggest temperature drop happens in the first 3 hours of the fridge and just hypothesising 30 mins in the freezer. Normally microwaves tend to be close to fridges so I usually set a timer for an hour if I stick a couple of beers in the freezer
Yes of course I saw the video and I knew everything he said because it's obvious. And you're such a kid to call me dumbass just because I say it's obvious U_U...
It would seem that according to Pigate's theories, that you are stuck in the "Preoperational stage" - it may serve you well to realize that just because you know something, does not mean that everyone knows it.
Mark DC without salt freezing point depression won’t take place. The salt effectively lowers the freezing point of ice, causing it to melt by absorbing heat from its surroundings. So salt helps speed up the cooling process drastically.
I bought a warm case of beer, put it in a cooler, one bag of ice over top, drove 500 yards to our firework parking spot, and it was ice cold. 4 minutes travel time. Not much ice left but it was all cold.
I love this handy hint. I'll put it to the test soon. I hate ice in my beverages. I don't have even one ice cube in any of my 3 fridges! Also, I'm a procrastinator about putting beverages in the fridge. This is a very useful tip for me!
I found out that putting a can of drink in water and ice mixture works faster than the fridge or freezer. Adding salt is a brilliant idea. The physics is easy to understand. But I never put this into practice before.
one very good reason to use this trick is camping, you may have bagged ice in a cooler, it may be (probably is) dirty (that is you cannnot put it in your drink) no freezer... plenty of water but maybe not clean enough to drink, ditto with any ice.... just remember if the water or ice is NOT clean, wipe or rinse off the beverage before you open it or put your mouth on it!
Just wrap a wet towel around the can and put in the freezer. It’ll make the can cold in 10-15 mins. if u can turn the freezer to the lowest temp and it’ll be faster
