  • The Klein Flask is based off of the mathematical Klein bottle originally designed by Felix Klein in 1882, Germany. The shape's "interior" is actually the same surface as its "exterior" and as a result it technically occupies (and holds) no volume. It is sometimes used as a 4-dimensional (or an embedded 3-dimensional) representation of infinity, much like the 2-dimensional Möbius Strip.
