5D Kaluza - Klein's Wormhole Between Two Event Horizons
  The solution of the 5D Kaluza-Klein's theory is obtained. This solution is a Lorentzian wormhole between two event horizons. It is shown that this solution can sew with (4D Reissner-Nordstr\"om's solution + Maxwell's electrical field) on the event horizon. Such construction is composite wormhole connecting two asymptotically flat region. From the viewpoint of infinite observer this wormhole is an electrical charge. According to J. Wheeler terminology this is "charge without charge".
