  We argue that heavy-ion collisions provide the best testing ground for
mini-black hole physics as $M_P\simeq 4 GeV$ for the gravity dual of YM and
give concrete evidence for a new extra dimension, that is visible only to the
strong interactions. We analyse the process of production evolution and decay
of the mini-black-holes by using recent results on gravity duals of YM. There
are several novelties compared with the traditional story of black hole
evaporation, including Bjorken scaling instead of sphericity, evaporation via
bubble nucleation instead of the Hawking mechanism and lepton-poor final
states. Multiplicities are estimated using shock-wave scattering techniques. It
is argued that high-multiplicity/high energy pp collisions will also show
similar characteristics of mini-black-hole production and decay.
