Now that she finished all the required spells and charms she should do, Kat was going to do the other optional charms. Just for the fun and to learn something you know. It would probably be helpful since Hogwarts was a mess right now. Oh, the things she'd do to keep the places in here clean. It wasn't just for her benefit though, it was for everyone... but she was sort of only thinking about certain people *cough* Slytherins *cough*. Looking at the board, Kat read the different optional charms.

HMM. Kind of easy. She'd try Tergeo because that was the easiest of them all. Hehe.

And yeah, she was going to siphon something. Like that wet thing over there. Oh yes, Katty can see you from afar. The Slytherin went over there and eyed the wet thingy for a moment. You'll be gone now, loser. Smirk. "Tergeo!" And then it was gone, all siphoned up. Byebye.
