If I am an astronaut on a spacewalk in zero-g, and I reach out and hold onto a pole (sticking out from a large space station) on front of me (with the pole parallel to my head-to-feet axis), and then I twist the pole in the direction of my fingers (around the poles long axis) I should be able to rotate myself around the pole, right? Now what happens when I let go of the pole... Do I start to rotate around my CoM, and also gain a translation at a tangent to where I let go?
