english: This is a Klein bottle wine bottle, which, although in four dimensions it shouldn't be able to hold any fluid at all, it's perfectly capable of doing so because our universe has only three spatial dimensions.
non_english: To je kleinova steklenica, vinska steklenica, ki jo, kljub temu, da v v štirih dimenzijah ne bi mogla biti napolnjena s tekočino, popolnoma lahko napolnemo, ker ima naše vesolje zgolj tri prostorske dimenzije.
