Last year I put a string of lights in an empty bottle of gin as a Christmas decoration.
It was very pretty but there were too many lights for the size of the bottle and it would get hot very quickly.
This year I replaced the lights with a smaller set of clear ones.
It's not nearly as pretty so I have to find a small set of multi-colored lights for it next year.
However, I think when Christmas is over I am going to mount that set of clear lights under the cabinet in the corner.
They make a great night light!
