Take two lead ions and smash them together.  If the energy is high enough, J-psi particles will be formed, at an even greater energy the J-psi particles will be annihilated and strange quarks will be made, along with this material.  The creation of it would signal the greatest freedom ever discovered for its constituent particles.  For 10 points, name this material in which protons and neutrons break up into their constituent parts.
