Introduction: How to Make a Self Freezing Coca-Cola (Or Any Instant-Soda Slurpee)

Picture of How to Make a Self Freezing Coca-Cola (Or Any Instant-Soda Slurpee)

Take any bottle of soda, and get it to freeze on command! This "super cool" trick works with cans of soda as well.

Step 1: Watch the Video!

This project was inspired by the viral YouTube video: "How to Chill A Coke In just a second!!" and the process of nucleation was inspired by "Self-Freezing Coke - Crazy from Kong!

I knew water could be turned to instant ice, but was amazed to see that soda could be supercooled as well.

Detailed Tips & Tricks for making "Instant Ice"

WARNING: Leaving soda in the freezer too long can result in failure of the container, and a big mess. Glass bottles are not recommended, as the ice expands when freezing and can shatter the glass explosively. Use of video content is at own risk.

Step 2: Self Freezing Soda

Picture of Self Freezing Soda

The anomaly of "self freezing soda" has been observed by many people, usually by accident.

Some people put a soda in the freezer to chill it, but then forget about it. When they've remembered and gone to get it, it's liquid until they open it, leaving them puzzled. Some people have noticed the effect by leaving the soda outside in cold temperatures.

There is a vending machine in Hong Kong that sells supercooled Coke bottles, and the instructions to trigger nucleation is the same as in this video, however they recommend taking a sip when the cap is on. I believe this is to increase the chances of impurities being introduced into the liquid, making nucleation more likely.

From what I've seen, the results in this experiment form an even thicker slush than the vending machine in Hong Kong.

Step 3: Supercool Your Soda

Picture of Supercool Your Soda

To get this effect, I shook up 4 bottles of 500mL (16.9 oz) soda in a freezer set at -24ºC (-11ºF) between 3:15- 4:00 hours. The longer they are in, the more dramatic and solid the slushy freeze will be. However, anytime after 3:15 hours there is a chance of them freezing before you take them out.

Shaking the up increases the pressure in the bottle, and actually lowers the freezing point a little.  

Every freezer will be a little different temperature, and I've noticed the location of your bottles in the freezer makes a dramatic difference on freeze times. For best results, choose one consistent location in your freezer, and play around with freeze times to see what works best for you. In my freezer, the middle of the center rack settles at -24ºC (-11ºF) and takes 3:15 to super chill 4 bottles.

Remember that the longer the freezer door is open, the more cold air will escape, and it will make your freeze times take much longer because your freezer has to cool down again. I've also noticed that the more frozen items you have in your freezer, the faster your soda will chill. In contrast, the less items in your freezer, the longer your soda will take to cool. Bottom line is, use a consistent environment for your experiments, and you'll get consistent results!

The trick to getting the 3 second slush, is quickly releasing the pressure in the bottle and re-securing the cap, flipping the bottle upside down, and back upright again. This is because the forming ice crystals will be moved around the length of the bottle, and trigger nucleation for the rest of the soda.

If you were to just take the cap off, ice will form, and it will slowly spread downward, but might take upwards of 2 minutes for the bottle to completely freeze.

Step 4: Things to Try

Picture of Things to Try

Once you've iced your soda, try pouring it into a glass to see how slushy it really is.  It has a consistency similar to that of a Slurpee.

It's actually the water that is forming the ice crystals, and you'll notice the ice will begin to float to the top, trapping some of the soda syrup, and making for a delicious carbonated ice slush.

If you were to remove the ice, the rest of the syrup would be more concentrated due to all the water that was taken out from it.

I found that if you opened the cap just enough to hear the bottle hissing, and held it there until it stopped, you could remove the cap completely and the soda would stay a liquid.

I put a metal bowl in the freezer for about 30 minutes, and when it came out, it got frosty from the moisture in the air.  If you pour your supercooled soda into a frosty bowl, it's enough of a nucleation point to trip the ice crystallization, and you'll be able to pour yourself and "instant slushy".

Some people have asked what would happen if you were to drink a supercooled soda.  Simple answer is that it's cool and refreshing!

As the soda ices, latent heat is released in the crystallization, and it actually warms up to just below freezing.  That's similar to just having a drink with ice cubes floating in it, so go ahead and enjoy it!

Step 5: More Things to Try

Picture of More Things to Try

If you try pouring your supercooled soda into a regular clean bowl, or glass, it will just look like regular soda.

Now drop a flake of ice, or ice cube into the liquid. 

As if by magic, the soda will crystalize until the whole bowl becomes slush.

There's one tasty treat ready for serving!

This also works with cans of soda as well, but it is tougher.  The freeze time is about the same, and the key to making it work is releasing the pressure from the can very very slowly.  This is much harder to do that opening a tab, but it is possible, and the soda has the same properties as the stuff from the bottles.  Obviously?

Step 6:

Picture of
I also experimented with 2 litter bottles, and had great results freezing them between 4-5 hours. The whole bottle slushifies in an instant if you shake it upside down for a second.

I experimented with Gatorade, Fresca, Mexican Sprite, Rootbeer, Orange sodas, Coke, Diet Coke, in bottle form, as well as in cans. I had super cooled success with them all!

Removing the pressure very slowly from the bottle, can keep the soda liquified, and give you the choice opportunity to play with supercooled soda outside of the bottle.

Well, there you have it!  That's how to freeze soda instantly.  If you're not a soda drinker, you can do this same trick with water!

If you haven't see the video yet, it's not too late.  See it here!

I did this some time ago, this was really fun to do!

Mschreib13 (author)2015-06-08

It is so obvious and nobody said it.

This Instructable is...wait for it... ...Is SUPERCOOL!!!

So how would you add gin to a bottle of tonic water before it goes into the freezer without losing the pressure?

silkier (author)MrRedwood2015-06-07

How about making gin ice cubes and then adding the tonic to it? Or maybe just put the gin in the freezer until it is very cold (and it gets a bit syrupy) and add the tonic to that.

Hmmm, sounds like I'm going to have to do some experimenting here.

pmshah (author)silkier2015-06-17

That would be rather difficult. You do know that the antifreeze additives for motor car fuel is alcohol based? Back in the 70s when I lived in Chicago I regular used a can full every time I "filled it up". Even on some days when the temp hit -20 I never had a problem starting my car at the first attempt.

GreenPhantom (author)MrRedwood2013-06-26

Well as long as the tonic isn't flat, I suppose you'd be able to just shake it to regain any pressure lost when opened. But the addition of alcohol would lower the freezing point considerably, and it might interfere with the supercooling or prevent from happening at all.

But a G+T slushie sounds might good

tovey (author)2015-06-09

I did this by accident with a 64oz bottle of coke back in 85 - 86.

I had it sitting outside the Gard shack for chilling. When I opened it and released the pressure; instant slush. After which I kept it in the shack to warm up.

gattlinggun (author)2014-05-22

Great instructable, but when i tried it the bottle exploded in my face and the cap flew off and hit the roof. I must have done something wrong

tovey (author)gattlinggun2015-06-09

So let me see if I have this right?

The bottle blew it's top!

Pun, obviously intentional.


Mizathel (author)gattlinggun2015-06-07

Lol, i hope the ceiling is fine. :)

mrmolamola (author)gattlinggun2015-05-13

Awsome!!!!!!!!!!!!! I wish that happened to me when I tried.

mzplik (author)2015-06-08

It also works with beer in cans.

hmuckleroy (author)2015-06-08

I just put it in the microwave and set the timer to a negative number.

almostmacgyver (author)2015-06-08

Love it!!! You come up with amazing things. That's why you're the King!!

jodie.white.144 (author)2015-01-28

Can it be done with a glass bottle, or would the bottle burst?

telogy (author)jodie.white.1442015-06-07

Quote .....'Glass bottles are not recommended, as the ice expands when freezing and can shatter the glass explosively'.

As stated in the Instructable glass is NOT recommended. The drink will try to expand while freezing and the glass MAY break making a mess or worse. A plastic bottle is the safest choice. Never try to freeze water or milk in a glass bottle.

Mizathel (author)2015-06-07

Can anyone figure out how long it takes with a 250ml mini bottle of zero Coke?

tobey.bevan (author)2014-08-11

Can you do it with a soft drink?

Mizathel (author)tobey.bevan2015-06-07

coke is soft drink

the discoverer (author)2015-06-07

Awesome!!!!!!!!!!!!!!!!!!!!! :)

leaf26 (author)2013-07-07

Tried it. doesn't quite work in my freezer because the edges freeze before the whole bottle is cold enough. The cap flew off when I opened it and *most* of it turned to slush like in the video and overflowed. It made a mess the first time, but at least I learned how to get a slushy out of a bottle of soda.

logan.downer.1 (author)leaf262015-03-07

cool it in the fridge first

rickardw (author)2013-07-15

have tried this a several times and it does not works?

logan.downer.1 (author)rickardw2015-03-07

well a little secret that i have found to work is that if you get your drink then cool it down in your fridge first then put it in the frezzer it should work a little better. and i set my freezer to -2 degrees fahrenhiet and it happened to a thing of juice concentrate

no more 7-11 for me this summer thank you

tycon4 (author)lurin2013-07-02

Yeah no more 7-11 for me either!
But I think 7-11 is cheaper than doing this

lurin (author)tycon42013-07-02

there is a store that sells one liter bottles of pepsi by my house for less than 0.75 cents with tax and deposit

That was sick I had a coke one tomorrow ill try a root beer!

kjsrocks (author)2013-06-29

this is the best thing ive read on instructables ever ps after the nuclieation i went to pour out my root beer and made a mess all over my kitchen

Shadow Ranger (author)2013-06-27

This is AWESOME!!!

mayagayam (author)2013-06-26

How Fun! :) Does this require carbonation, or can it be done with non-carbonated bev's?

andrew8172 (author)2013-06-26

I've got a coke in the freezer right now. Thanks for this awesome instructable.

yellowcatt (author)2013-06-26

I did this a couple of years ago but never even thought to film it for an instructable.
On one occasion I had filled a soda bottle with water and left it in the freezer over night so I would have cold water for a day out. When I opened the freezer the water was still liquid, at first I thought the freezer was faulty but when I put the bottle down on the work top the water all turned to ice in about 30 seconds.

creshawn (author)2013-06-26

i had lots of fun with this instructable. i do it almost everyday just for the fun of it. but when i tried to do it with gatorade. the gatorade came out with a wierd texture.

tony_bostony (author)2013-06-25

YEAH. It's not really self-freezing. You need a colder-than-frozen bottle to start out with. This is a nice parlor trick, but not practical for any real situation where a cold beverage is AN EMERGENCY (caps lock rage).

Oscelot (author)tony_bostony2013-06-25

For things like that, I suggest keeping a container of salt water in the back of the fridge. Stick your drink in it - it'll be cold in very short order.

RichardBronosky (author)2013-06-25

I'm not trying to be mean here, but this really isn't very useful to anyone unless they are hearing for the first time that such a thing is possible. You state, "In my freezer, the middle of the center rack settles at -24ºC (-11ºF) and takes 3:15 to super chill 4 bottles." It would be nice if you could use an IR thermometer and tell us the temperature of the bottle that produces good results.

I have researched this before and believe I saw that 20ºF is a good temp to go for. I had considered buying a mini fridge and rigging it to stay at the perfect temp just for slushifying drinks.

leaf26 (author)RichardBronosky2013-06-25

I just learned this for the first time, though I knew it was possible. I think this will be VERY useful to me for ice cream sundaes or as a standalone dessert. It's also a good idea for parties to show off a magic trick.

RichardBronosky (author)leaf262013-06-25

I think you miss my point. Doing this is useful. But his instructions only apply to his exact freezer this time of year. 3 hours and 15 minutes isn't even likely to work for him other times of the year.

However, crowd sourcing information like:
Water 25ºF
Coke 20ºF
Diet Coke 12ºF

...would help every reader. With the right equipment we could follow those instructions and get the results. With the instructions given a very low number of people are going to have success. The comments here and on Facebook confirm it.

leaf26 (author)RichardBronosky2013-06-25

Thx, I'll use that temperature

BeoWulfe (author)2013-06-25

Nice quaich. It's the main reason I clicked on the thumbnail. Now you gotta rinse it out with a little single malt :-)

wavemaster447 (author)2013-06-25

Suprised to see this worked with diet sodas as well - approximately how long did it take to freeze the cans? There's a much higher element of risk here with the sodas than we had with water :P
