Holding a wine bottle by the neck isn’t too hard. What I don’t really know how to do is spilling the wine/beer. Translucent liquid plastic. I’ve seen it, I just don’t know how to do it. I suspect a thin clear plastic piece from mug/bottle to the mouth, coat with clear 2 part epoxy, let dry, then continue to build it.
But it sounds like so much work and maybe that’s not the way to do it
