It's a space storage box that has 4 containment fields. You can insert different boxes into the containment fields to storage different objects like forks, spoons,etc. Each box has a magnet beneath it, and there is also a magnet bar in every containment fields to stable the boxes. If you want to stable the box to the containment field, you take the magnet bar out and reverse it to the opposite charge to the magnet beneath the box( opposite charges on each sides of the magnet will attach together, and same charges repel). If you want to release the box from the containment field, you take the magnet bar out and reverse it to the same charge as the magnet beneath the box, because there is no gravity in space, the box will fly out due to repulsive forces.
