The cafeteria area was mostly empty except for Mariana, bored and out of paper (she'd have to ask for some more next time her family visited, or maybe steal some from art therapy). She was instead methodically manipulating water in a Styrofoam cup, letting it go up and down. As a reward for good behavior, she was allowed to, sometimes, use her powers for personal amusement, though this was often taken away when she pulled dumb little pranks. 

An exasperated sigh escaped her. She turned the water to ice and laid it upon itself, creating strange, abstract forms. Perhaps she could use this as a sort of artistic medium? She pondered.
