Black holes are the densest form of energy, and in the presence of compact dimensions black objects may take one of several forms including the black-hole and the black-string, the simplest relevant background being R3+1 * S1. Recent understanding of the first order nature of the transition indicate a powerful ``hysteresis'' curve, where black objects may undergo fusion or fission during a tachyonic decay with Planck power and duration of the order of the size of the compact dimension L. Such explosions which scale with L could be test signatures for large extra dimensions in either astronomical observations or accelerators.
