Enjoy every part of the wine you drink, from cork to bottle. I'm a huge advocate of recycling wine bottles and corks. In fact, we reused several corks and bottles at my wedding as table number holders.
Craft Stick Catapult - I made 4 of these in 5 minutes and they work great! You need craft sticks, 4 rubber bands, hot glue or tape, and a bottle cap (I cut apart an egg carton because I didn't have any bottle caps).
