Because of the great amount of knowledge Walter White has picked up from being a teacher of Chemistry, the methamphetamine came out near perfect on his first batch. Being 99.1% pure, the meth came out a sky-like shade of blue, quickly making Jesse and Walt a large amount of money. After selling to their first buyer, they were immediately famous. The notorious "Blue Sky" made its way around the streets, towns, and states surrounding them, sparking interest from big name buyers and sellers, leading Walter and Jesse to both danger and success.
