It's been a long time since I've ever tried carbonating fruit again on purpose, but if you read the last post, you know that we bought some dry ice recently to make some witch's brew/homemade root beer. We had plenty left over after making the drink, so alongside the other science experiments, I decided to use some of the extra dry ice to carbonate some fruit.
Step 1: Cut up some fruit. Make sure the fruit holds a decent amount of juice (apples, oranges) and won't dissolve overnight (bananas.)
I cut up some apples, oranges, and then added some grapes to a tupperware cannister. You want to make sure it's something you can seal, but not so rigid that it could burst or explode.
Step 2: Place fruit into a sealable container.
Step 3: Add a small piece of dry ice and seal container.

So if you are going to make some, try a piece that's closer to a regular ice cube size. And make sure your lid can screw on rather than pop on. After it had melted enough that the lid was no longer flying off, I put the whole thing into the fridge for 24 hours.
Step 4: Store in a cool place for 24 hours.
Step 5: Eat quickly after opening.
We opened it up the next day for lunch and enjoyed our fruit with a "bite." From what I read looking for other people who have done this on the Internet, the fizz wears off quickly, like within a half hour, so you want to eat it soon after opening.
Happy carbonating!

We had to look all over the place to find a dry ice merchant. It's no longer sold at any grocery stores nearby. We did a Google search for dry ice and Fort Worth to find a site.
