Step 1: Melt Your Candle
Pouring the wax:
Note: You will make a mess.
If you want, before you pour the wax, you can squirt some cooking spray into the bottle to make removing the candle from the bottle easier later on, but I didn't try it so I can't predict how it will go.
Stick your funnel inside the the beer bottle and *carefully* pour the wax into the bottle. Quickly move on to step 2.
