This is how you create a wormhole in your bedroom.
Honestly as a kid I thought I had opened a wormhole in my bedroom. I was sleeping on the floor on an inflatable mattress which had an attached bedsheet that didn't come off. During the night I turned on my side, flipped the bed, it hooked onto the wardrobe door handle and I was suspended upside down diagonally.
I'm convinced bedding defies physics at this point.
Good news! You've got the longest side 100% of the time.
Felt

What the hell is that supposed to be, a Klein Torus?
Yes, someone please help. Confused minds want to know! (Me, I'm the confused mind)
This what happens to my duvet at 3am when I wake up and the cover has misaligned with the duvet and my foot is wrapped up with the cover and around my leg and my body is now in full alarm mode as it tries to untangle itself and wake up my brain in panic mode
I think it's just a less illustrative way of rendering a Klein Bottle, yes.
Grab the middle and pull it through the center
