Carbonated ice cream?  ...Really!  And here's how to make it with a few simple ingredients, and a bit of dry-ice.

Step 1: Watch the Video!

WARNING: Dry Ice is extremely cold! (-78C/-109F) and can cause instant frost-bite to exposed skin.  This project should not be attempted without adult supervision and adequate training. Ingestion of dry-ice may cause serious internal tissue damage.  If Dry Ice is ingested, drink copious amounts of warm water as soon as practical.  Misuse, or careless use may result in serious injury.  Use of this video content is at your own risk.
This is one of you're best ideas ever. My brother and I love you're videos, and we did the one were you make instant ice. thank you. By the way I am totally going to have to make the metal foundry.
<p>With this tool you can make invitations and videos for halloween http://goo.gl/e93nhK</p>
<p>Your Highness. Or should that be Mr K Random? How does one address you BTW?</p><p>Anyway, Your Highness (to be on the safe side) thank you for some very fine instructables. I always know when I see one of yours that it will be worth reading. This is no exception - it's just what I had in mind for a small kids' project.</p><p>Do you recall, by any chance, how much dry ice you needed for a certain amount of ice cream? I'm wondering about doing this but am rather CO2 limited and so I don't want to make a gallon of sludge when I could be making a pint of beautiful ice cream.</p><p>You said you got 5lbs of dry ice from a 15lb extinguisher. Did you use all of that? I have at most 4 x 1kg extinguishers (just shy of 9lb total). What type of amount do you think I can aim for with that?</p><p>Any help appreciated.</p><p>Ugi</p>
If a 5 pound block costs you at most $5, why would you use up a fire extinguisher?
<p>You can buy CO2 in the US but elsewhere in the world it's nearly impossible to source. In the UK you'll pay &pound;30+ for delivery no matter how much or little you want, for example.</p>
In case you already had one
Co2 fire extinguishers are refillable.
Also, I would think it is easier to crush it up into fine bits since it is already &quot;snow&quot; instead of a single hard block.
He wanted to.. .it's quite all right
If it melts, will it still drip on you?
Tried this last night. It was excellent and my housemates loved it! I'm gonna do it again and include a banana puree. <br>I used normal sugar though, not sure if powdered would make a difference. <br> <br>I'm so glad you're videos are back up, I didn't realize I should've started archiving them. XP <br>You're easily my favorite youtuber.
tried this - very tasty and fun to make. my one son (who loves sweets) really enjoyed this but my other son didn't, he felt the fizzy-ness was too much. I thought it was really cool. It's sorta like pop rock ice cream. if you added some fruit flavoring it would be more like pop rocks. either way it's good stuff (and who knew dry ice is safe to eat!)

Careful, you can't be sure your dry ice is foood grade! I Guarantee a fire extinguisher is not! Its made from air using a pump, usually powered by gasoline engine so the pump exhaust may be included in your dry ice, yuch, carbon monoxide and partially burned gasoline! let some dry in a pan and if it smells off DO NOT USE.
This is an awesome idea! How long will the ice cream keep if you store it in the freezer after making it? WIll it keep like a normal tub of ice cream?
It's not going to &quot;keep&quot; in a freezer. Your freezer temperatures are typically slightly below the freezing point of water. According to one website I saw, PThe ideal freezer temperature is 0 Fahrenheit (-18 Celsius) for storing food. And -10 Fahrenheit (-23 Celsius) is recommended when freezing food.&quot;(see: http://www.favoritefreezerfoods.com/ideal-freezer-temperature.html). A typical household freezer won't be able to go much lower than that. However, dry ice sublimates (changes directly from the solid used in this ice cream into a gaseous form - there is no such thing as liquid carbon dioxide at ordinary room pressure) at &minus;78.5 &deg;C (&minus;109.3 &deg;F) at Earth atmospheric pressures. Sooooo....the carbon dioxide (fizziness) part of this icecream will start to break down right away. But...the frozen half and half, etc. would remain frozen in your freezer. But it would be ordinary ice cream, not fizzy icecream after some time. How much time? I don't know, but it would keep longer in lower temperature surrouundings... like your freezer. I think it would also help to keep it in a styrofoam box inside your freezer. The sublimating CO2 takes heat energy out of the rest of the ice cream, helping keep it at a lower temperature than your the rest of your freezer. But don't seal it tightly....don't want a &quot;CO2 icecream bomb&quot;.
I'd never heard of this until a week ago when we decided to make this for a fund raiser for a club at school, and now I see it here.... Cool! =)
Great idea!
