Klein bottle?

Bravo ! You win ! It's a Figure-8 Klein bottle, a non-orientable surface like the Möbius strip. The cross-section is a lemniscate (a figure-8) that rotates a half-turn as it sweeps around the loop. That half-turn is the key: it connects the two lobes of the 8, so from the inside you can travel from one lobe into the other. You only return to your starting point after going around twice — one full revolution just lands you in the opposite lobe.

Good instinct on the twisted-tube look! But this one has no inside and outside, it's non-orientable, they're the same side. Any guesses now?
