What Goes Around Comes Around

The two of them were oddities

Well known in well-known parts

Frequenting lines of streamers

Among the bendy fits and starts

With relish flaunted differences

In concentric senseless style

Combined insanity with vanity

They led the world in single file

Tiptoeing round the cutting edge

Became the peak of what’s the point

Not saying or betraying why

For neither aimed to disappoint

Never ones for taking sides

They were continuous in the loop

Forever getting feedback from
A transformation simmering soup


Question: How long will wine stay fresh in a 'Klein Wine' bottle

A Klein bottle is a non-orientable surface, where there is no distinction between inside and outside. So unlike a sphere, where you cannot pass from the outside to the inside without passing through the surface, in a Klein bottle you can do just that. If you were very small, an ant say, you could start at any point, and keep crawling until you reached the other side of the surface, without passing through any surfaces, and without needing to cross any edges.
