In World of Warcraft, how to complete the task of looking up at the stars?

Looking up at the starry sky is the level 20 task of Night City. The copper tube needed in the task is for engineering. Players can learn engineering to make their own, or they can go to the auction house in Stormwind to buy it. In addition, the engineering supplier next to NPC will supply bronze pipes in limited quantities. If you are lucky, you can buy them from him, so you don't have to run back to Stormwind or go to an engineering class.
