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.

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

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.

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.

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

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.

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

So let me see if I have this right?

The bottle blew it's top!

Pun, obviously intentional.

:)

Lol, i hope the ceiling is fine. :)

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

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

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

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

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.

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

Can you do it with a soft drink?

coke is soft drink

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

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.

cool it in the fridge first

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

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

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

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).
