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

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.

Can you do it with a soft drink?

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

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

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

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

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

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

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.

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.
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).
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.
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.
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.
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
etc...

...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.
Thx, I'll use that temperature

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

You're on YouTube AND intructables? I love this! Keep It up!
Can I do this with a can of soda without it exploding?
