Looking around for something to use, Stan spotted a water bottle left in a corner. It was small, but it would show the basic charm.
Stan pointed his wand toward it and positioned the other hand behind the first, as though he were holding onto a rope attached to the bottle. "Absentus Funis," he said softly and pulled back with his hands. The bottle jumped backwards, as though it really were being yanked by a rope.
He turned to her (not looking at her lips!) and shrugged. "We have something bigger? We could work our way up."
