I get the joke, but for once I actually think this might be more comfortable to sleep on. Got a little upward tilt for the head so you can use less stuff as your pillow.

I think it's a bit tight to work a skate ramp even if you built an access ramp matched with the table to have sufficient speed, it just seems too small of a curve.

Slams hand on the underside of the table on the first attempt.

It doesn't need to turn, it's a continuous angle if you unfurl it so if you got the angle and speed right it should stay centered and travel the loop.

What if you rotated the ball at the same time?

Depends on where you launch it from. If you launch it from the end, that would happen. But if you were to launch it from the beginning of the loop you could give it the proper inertia for it to be able to go through the loop.
