My boyfriend and I don't drink much alcohol, but when we do, it's absinthe. Fortunately, the bottles are super cool... and unfortunately, I have a few wine racks full that are just collecting dust.
I picked one up the other day and thought about the wine bottle lamps some people make... but I didn't have the tools to cut a hole in the bottom of my bottle and put in a light bulb.
So I dug around in my boxes and found a string of battery operated green LED lights I got at Daiso (a Japanese dollar store on the west coast), and I shoved all the lights in the bottle, leaving the battery pack to rest on the back of the bottle.
Now it looks like I've got a bunch of little green fairies caught in my pretty bottle! Bwahahaha!
This would work with any colored glass bottle, and I'm sure an outlet powered string of lights would work fine as long as the space between the last light and the plug is long enough!
