How does one inflate a Klein bottle (since inflating is putting air (or some other gas) inside a container)?

"Damn you, math!"

[NotATopologist]

Obiously, any "real" 3d representation of a klein bottle will have walls with thickness greater 0. You could inflate those walls, like a twisted air mattress. Where's the kickstarter?

[J Arthur]

The same way one exflates it.

[gvest]

There is a much simpler way of solving this problem- simply having sex outside one thing but inside another (which also contains the first thing.)
Unless the whole point was to engage in mental masturbation...
