Alright folks, tomorrow I'm heading to a nearby hardware store that's rumored to have a homebrew section. I already have a 1 gallon carboy with airlock, a capper, caps, 12 22oz bottles, 4 ft. of 3/8 tubing and a spring-tip bottle filler. I know that I definitely need a hydrometer and another 1 gallong carboy, but what other goodies should I be sure to pick up? I'm going to be starting to take regular hydrometer readings and I'll need to rack soon...
