Triple-nested Klein bottle



Here's glassblower Alan Bennett's astounding triple-nested Klein bottle, a beautiful thing:


A single surface model made by Alan Bennett in Bedford, United Kingdom. It consists of three Klein bottles set inside each other to produce, when cut, three pairs of single-twist Mobius strips. A Klein bottle has no edges, no outside or inside and cannot be properly constructed in three dimensions.

Klein bottle, 1995.
