The Unfreezing Element Helium refuses to freeze solid at normal pressure. Cool it to absolute zero and it remains liquid. Only extreme pressure forces helium into solid form. The atoms move too quickly to lock together. Quantum mechanics keeps helium eternally fluid. Scientists must apply 25 times atmospheric pressure to freeze it. Helium breaks the rules of normal physics.
