To make carbonated fruit you only need to gather a few things:Fruit
When making carbonated fruit it's best to use firm fruits, like oranges, apples and pears. I tried doing it with softer fruits like kiwis, strawberries and bananas and it just doesn't work as well. Apples in particular seem to work the best.Bottle or Container
You will need a plastic bottle or a container to put the fruit into. I have found that a wide mouth Nalgene works best. You can use an empty 2 liter soda bottle however, just be careful not to add in too much dry ice, more on that later. DO NOT use a glass jar. The bottle will be under pressure and broken plastic is safer than broken glass. If you have a vessel that is designed to take pressure, like a beer keg for example, than by all means try using that.Dry Ice
The final thing you will need is a block of dry ice. You will only need a tiny tiny amount of dry ice to make the carbonated fruit, but its hard to buy less than a large block of the stuff. Now, chances are that you have never seen dry ice for sale. You can't make it on your own and you might not be able to find so easily.
I used the Dry Ice Directory
to find out where it was being sold locally - they have listings for all over the world. I live in the east bay of California. I was surprised that In all of Oakland there was only one distributor - the AM PM Gas Station on Market and Grand in West Oakland. They oddly enough had a ton of the stuff for sale, and they are open 24/7! I was very impressed that I could buy dry ice anytime I wanted even if it was only for sale at that one place.
**Before you go to buy the dry ice please refer to thisDry Ice Safety Info
website. I am not going to go through all of the safety precautions that should be taken in this instructable, so take a minute to familiarize yourself with its possible safety hazards.**
