- Falldog, on 06/13/2008, -7/+253MythBusters mother *****, do you watch it?
...apparently not - reisrocks, on 06/13/2008, -4/+143Was the article called "how to make beer cold in 3 minutes, with a ton of ice and a freezer" I wouldn't have bothered reading it.
- Salviati, on 06/13/2008, -10/+137The salt doesn't make nearly as much of a difference as the author seems to think. It is true that adding salt to the water will lower the freezing point of the water by a couple of degrees, but it won't make a lot of difference over 3 minutes. And besides that, the freezer doesn't instantly drop the temperature of the water to the new freezing point. In three minutes, the water probably won't change by more than 0.25 degrees. The real difference here is that the drinks are in contact with water instead of air. If you set the drink in the freezer without it touching anything, it will take a long time to cool down because air is a very bad thermal conductor. Water is a very good thermal conductor, so it removes the heat quickly.
Think of it this way, if water at 31 degrees (with salt) can bring the drinks from 80 to 40 degrees in 3 minutes, water at 32 degrees (without salt) won't make a real difference.
Also, stop referring to this as 'dry ice'. Dry ice is frozen carbon dioxide and it is so cold it boils at -100 degrees! That would freeze your beer on contact. - DeskFlyer, on 06/13/2008, -2/+92CO2 fire extinguisher will give you cold beer in about 10 seconds.
- humperdeath, on 06/13/2008, -1/+81Actually, his cut'n'paste skills are not all that sharp, as he missed the very last word (beer).
- thebaron2, on 06/13/2008, -2/+81He'll be thanked if/when the site goes down.
- inactive, on 06/13/2008, -24/+88yup thats exactly what it says in the story, congrats on your wicked copy-paste skills.
- ironeus, on 08/01/2008, -8/+66ah, the salt factor lowering the freezing point -- brilliant!
- natchiketa, on 06/14/2008, -4/+38Did you say that like Samuel L. Jackson as you were typing it? Cause I certainly read it that way :)
- Salviati, on 06/13/2008, -0/+34This is NOT dry ice. Dry ice is really frozen CO2, and boils at -109 degreesF.
- snea, on 06/13/2008, -1/+30I can see from the image that guys beer ended up tasting like ***** after being stored in the garage at 90 degrees.
- colasrtney, on 06/14/2008, -3/+32ICE MAKES THINGS COLD, GOT IT!
- doctechnical, on 06/13/2008, -0/+29Is there some place where "dry ice" means something different than what it means in the US?
Here "dry ice" means frozen CO2. "Dry", because it sublimates (goes from a solid to a gas) skipping the liquid state. - RealmDown, on 06/13/2008, -2/+28Shut up, troll.
- inactive, on 06/13/2008, -4/+29your mom gets cold in 2 minutes.
- SpaceDreamer, on 06/13/2008, -5/+30it works about as well without salt,
and without placing it in the freezer. - kidsix, on 06/13/2008, -4/+29buy beer the day before. put in fridge. cold the SECOND you want it to be.
- inactive, on 06/13/2008, -2/+23Ha, they proved this years ago.
- UNCCEJ1010, on 06/14/2008, -0/+20The solubility of NaCl in water is 35.9 g/100 mL, therefore there will be 359 g of NaCl per kg of water (the density of water being 1g/mL) in a saturated solution.
With a molar mass of 58.44 g/mol, that gives 6.14 moles of NaCl, and a molality of 6.14m (1kg H2O).
With a van't hoff factor of 2 for the 2 ions in solution and a molal freezing point depression constant of water of 1.86, this yields a freezing point depression of 22.84 C.
Granted, this is using the solubility of NaCl in water at 25 C, which would be somewhat decreased at a low temp. Also, the van't hoff factor would be less than exactly 2 due to some association of the Na+ and Cl- counter ions in solution and the failure of water to complete solvate the charged species.
And yes, i realized I wrote "... the a..." in the above post after the edit time expired when i was done typing this. - upick, on 06/13/2008, -60/+79This is a nice trick!
1. He took 6 hot beers from my garage and he placed them into a steel pot from the kitchen
2. He tossed in enough ice cubes to completely cover the beer
3. He then filled the pot with water
4. Next, and this is the trick, he tossed in (what must have been) 2 cups of table salt.
5. He took a large wooden spoon and stirred this thing up to be sure the salt dissolved.
6. He placed the concoction into the freezer and in 3 minutes we had ice cold - chrispr, on 06/13/2008, -0/+19Painful like an orgasm.
- colasrtney, on 06/14/2008, -1/+17No he didn't and he's never seen Pulp Fiction.
- zephyr42, on 06/13/2008, -0/+16You might wanna get that checked out.... That's not normal.
- SonicRush, on 06/14/2008, -2/+17The salt makes all the difference if you're trying to chill beer in 3 minutes. It allows the ice cubes to dissolve into the water much faster, lowering the temperature of the water so that it can chill the beer faster, because of the larger difference in temperature between the can and the water. The water doesn't start at 32° right away. It comes out of the faucet, remember.
And 0.25 degrees? How arbitrary. - SpaceDreamer, on 06/13/2008, -1/+15placing it in the freezer doesn't make much difference either.
the kitchen sink is more practical. No need for a bucket. - V0lk, on 06/13/2008, -0/+14I usually buy my beer pre-chilled.....saves on labor and salt costs.
- hammerpants, on 06/13/2008, -4/+17Simpsons...errrr...Mythbusters did it!
- humperdeath, on 06/13/2008, -1/+14Of course, I bet everybody has plenty of room in their freezer for a 6 quart steel pot. NOT!
- SpectralSounds, on 06/13/2008, -2/+14Sorry, I guess we should watch American Idol and Big Brother just like you do... right?
- UNCCEJ1010, on 06/14/2008, -0/+12Actually the a saturated solution of NaCl will have a significant impact on the freezing point.
It would be close to -20 C.
(see reply for more detail) - JennRN, on 06/13/2008, -2/+13In the operating room when we need to cool fluids FAST in an emergency we use a bunch of ice and rubbing alcohol. Skip the salt, it doesn't work half as fast. Save the salt for making homemade ice cream.

surgery.about.com - betona, on 06/13/2008, -0/+11You can do a single beer in 60 seconds if you lay it on its side, push it down into the ice and then spin the can where it lies in the ice for a minute. It's all about the physics of heat transfer and it works great.
- brianrwalters, on 06/13/2008, -3/+14You don't actually need the freezer...
But then again, while this trick does work - make sure you clean the top of your cans thoroughly before drinking, or else you'll have a very salty-flavored beverage. I say this from experience... - doctechnical, on 06/14/2008, -0/+11If the ads were actually authentic, and drinking the dreadful draft caused bountiful bodacious blond bimbos to brush their Brobdingnagian boobs boldly on my body, I would not only quaff in quantity, but give up my awful alliteration attempts.
- Hosalabad, on 06/14/2008, -1/+12Yeah, one beer and a extinguisher recharge bill.
- doctechnical, on 06/13/2008, -2/+12Nothing "gets cold", period. There's simply a movement of heat from one thing (warm beer) to another (ice/water/salt mixture).
/pedant - DrunkTomato, on 06/13/2008, -0/+10WHAT ARE YOU, CHUCK NORRIS or SOMETHING?
- fatTJ, on 06/14/2008, -0/+10Say what again.
- twst1up, on 06/14/2008, -0/+10wow...ur cool
- doctechnical, on 06/13/2008, -1/+10Depends on the beer. If it were a *****-beer to begin with (like Bud), I don't think the heat could do much to make it worse.
- sjmulder, on 06/13/2008, -1/+10I read "How to kill a bear in 3 minutes". I wondered, why would it take that long.
- doctechnical, on 06/14/2008, -0/+9"If you set the drink in the freezer without it touching anything..."
...you have managed to levitate the beer, and have achieved True Enlightenment.
-- Zen Flesh, Zen Beer - jamesdew, on 06/14/2008, -0/+9ha! He showed you you cold wet handed fool
- yojiffyskippy, on 06/14/2008, -2/+10Lighten up Francis.
- chrispr, on 06/13/2008, -1/+9Chill a beer in 3 minutes, if you're willing to devote extra time,energy, and resources to getting a huge vat of ice, water, and salt.
I'll just wait an extra 15 minutes. - peppino, on 06/13/2008, -3/+11The trick to drinking beer all day and night is to avoid eating food (just drink beer).
- idavidtang, on 06/13/2008, -4/+12For a quick second I thought the title was, "How to chill a bear in 3 minutes".
- ivansusanin, on 06/14/2008, -2/+10that's what she said
- quomen, on 06/14/2008, -0/+8What?
