We describe a number of striking features of a class of smooth solitons ingauged and ungauged minimal supergravity in five dimensions. The solitons areglobally asymptotically flat or asymptotically AdS without any Kaluza-Kleindirections but contain a minimal sphere formed when a cycle pinches off in theinterior of the spacetime. The solutions carry a local magnetic charge and manyhave rather unusual ergosurfaces. Perhaps most strikingly, many of the solitonshave more electric charge or, in the asymptotically AdS case, more electriccharge and angular momentum than is allowed by the usual BPS bound. We commenton, but do not resolve, the new puzzle this raises for AdS/CFT.
