My kids don't take the advice of anyone who has Kleinbottles in their crawlspace, fdsa. And I doubt if removing those glass manifolds would have much effect. -C

I checked my basement Klein bottle stock and it looks like I’ve got zero volume. How much can I put you down for? (we sell by the litre)

I have a Klein bottle on the shelf behind me, and next to it sits a Klein bottle opener, just in case. https://www.kleintools.com/catalog/branded-collection/klein-...

I wanted it fractal glass etched with clifstolls name, but they wouldn't do that.
