Hermione sat- what would time travel feel like? would it make her dizzy? probably better to sit down, just in case- against the wall furthest from the door, the one connecting the stalls to the sinks. She eyed the sinks warily for a moment before turning back to the matter at hand. The device was quite small, fitting easily into the palm of her hand. It was also flat, probably for the convenience of wearing it as jewelry. A dial on the side connected to a thin rod clearly visible through the thick protective glass that made up the ornament. It's purpose, however, appeared to be executed entirely through that tiny little black cylinder.
