Step 1: Gather materials and tools
-a suitable bottle:
I used a champagne-like bottle from the Brooklyn Brewery's delicious refermented brew, Local One. Use any bottle you like, so long as it's heavy enough to balance your lamp hardware.
I bought a package at Home Depot with all the parts, but you can easily gather them: a stabilizing plug to fit your bottle opening (rubber stopper) with a hole in the middle, a short section of threaded bar to fit inside the stopper, a basic bulb socket with cap, switch, and shell, some electrical wire, and a wall plug.
