cleaned liquor bottles for use in aquariums?

[F1 VET]

I've done this way back when, belvedere vodka has plastic cap so it won't leach, fill it up with water and squeeze green highlighter in it, cap it now when its near a blacklight it will glow very brightly, put in in tank let it sink and free night light

You could always etch the brand logo into the glass of the bottle. I love the wine bottle idea!
