When something is possible, you can do it. There are so many scenarios when something can be possible (meaning that you can do it) or impossible (meaning that you can't do it). There are scenarios said to be impossible but they could be possible.
Twisting is when something rotates. So many things twist, including ourselves, our peers, animals of any kind, and probably living things. I think that so many things twist that we don't know of.
