Klien Bottle

| Klien Bottle model | Klien Bottle flasks |
Developed by Felix Klein in 1882 by combining 2 *Möbius Loops together forming a single sided bottle with no boundary.
It is a representation of an object that is inside its own outside - thus containing itself!
A true Klein Bottle has to pass through itself without a hole - requiring a 4th dimentional Nexus to pass through.
*Möbius Loops

| Developed by the German Astronomer August Möbius (1790-1868), is a single sided strip of material with a 1/2 twist before connecting the ends. |
