    "abstract": "Casimir pistons are models in which finite Casimir forces can be calculated\nwithout any suspect renormalizations. It has been suggested that such forces\nare always attractive. We present three scenarios in which that is not true.\nTwo of these depend on mixing two types of boundary conditions. The other,\nhowever, is a simple type of quantum graph in which the sign of the force\ndepends upon the number of edges.",
