A universe worth?

If you want to talk about holding water there would need to be an inside and outside, right?

[–] moody@lemmings.world 4 points 21 hours ago (1 children)

This has three separate inside sections, unlike an actual Klein bottle.

[–] morphballganon@lemmy.world 2 points 17 hours ago (1 children)

Isn't the inside of one section the outside of another though?

The top openings are also the bottom of the bottles. Or rather, they are an opening for one bottle and the bottom of a second bottle.
