CAUTION: DON'T SEAL THE CONTAINER TOO WELL! THIS COULD RESULT IN HIGH PRESSURE, BREAKAGE, AND PEOPLE BEING HURT! ALSO DON'T DRINK THE DRY ICE!
Sometimes, someone asks a question and I nearly know the answer.
Well, a couple of years ago, my wife and I experimented with carbonation. I've brewed beer some and done a lot of bottle carbonation and force carbonation, but I no longer had access to a CO2 tank, so our experiments were done on the cheap.
Please note that we used fruit, not bourbon. Results may vary.
I found dry ice at a local Kroger (grocery store). I noticed it on my normal weekly shop. Hopefully, anyone who wants to do this can find it, too.
Get a tupper or other container with a friction fitting top (not screw top!). Maybe .5 L/1 pint.
Add a piece of dry ice the size of one finger joint.
Add your liquid or fruit of choice (liquidy fruits like strawberries and oranges work best, but slice them) Fill it not more than half way.
Close the tupper and tape the lid down.
Place in refrigerator and wait 1 hour or more
It should be quite tangy!
