Blue Sky" (also known as Big Blue, Blue Magic, Fring's Blue[1], or simply Blue) is the street name which has been coined for the notoriously potent and 99.1% chemically pure crystal methamphetamine manufactured by Walter White and Jesse Pinkman. Since its introduction to the market, there have been a few temporary accomplices who have helped Jesse and Walter cook with the blue meth formula: Brandon "Badger" Mayhew, Gale Boetticher, and Todd Alquist.
