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.

In 2006, researchers from the University of California, Davis announced finding from genetic mapping that amino acids in wine that have been slightly modified by the fermentation process may be the cause of wine related headaches.

But what was unexpected was that these researchers did MRI brain imaging while the people were drinking the wine, and not only did they say they enjoyed the more expensively labeled wine more their brain actually registered as experiencing more pleasure from the same wine when it was labeled with a higher price tag.
