To date, the anomaly has been observed most clearly in the two semimetals Na_3Bi and GdPtBi. I will discuss what Weyl Fermions are, and how they may be realized in real materials. The realization allows the chiral anomaly to be observed in a crystal. I will explain what the chiral anomaly is and remark on its historical context, starting with pion decay. Finally I will discuss several tests that buttress the conclusion.
