I'm now grinning like a fool because I'm imagining floating around the room, weightless. A gentle push off the floor sends me forward and up at an angle, but I accidentally gave myself some spin; I'm slowly rotating heels-over-head -- and I tuck my head in and collide with the ceiling with my shoulders. This cancels out most of my momentum, leaving me slowly drifting away from the ceiling without anything to hold onto. I slowly move my arms down to about my waist and push off against the ceiling; this time, since I was pushing around my centroid, I go slowly toward the floor. Which also doesn't have anything to hold onto. Damn, this room was not designed for weightlessness. Here endeth the delightful fantasy.
This made me happy by reading it.
