If, for whatever reason, you don't want a big bottle labeled Moonshine at your sister's volleyball game, you can go incognito with this Spike Your Juice ($10) kit. Simply grab yourself a 64 oz. bottle of juice, dump in one of the six included yeast packets, pop on the airlock, and wait. In 48 hours or so, you'll have your own homemade hooch with an alcohol content of up to 14 percent. Great for parties, fooling in-laws, or as a holiday gift for buddies doing hard time.
