Dood. Read the label on the case. Carefully.
Brewing this in the traditional way like this actually does result in a TINY amount of alcohol, but it'* so small, it doesn't really matter.
Playing around a little. I just mixed up some sugar water in a plastic bottle, and dumped in an entire packet of dry (beer) brewer'* yeast, then put a balloon on the neck. Trying to show Katie what the yeast does to the sugars, and what the result is. I'll post pics as it blows the balloon up.
