Just stumbled on a cool item. Its call White Smoke Flare. You throw one in a specific location and it lasts for 5 minutes. I like throwing them in the doorways of the Auction House and Bank. I get bored sometimes because I never get to leave Stormwind City.You can buy White Smoke Flares from Bossi Pentapiston, Qiff, Skyguard Pyrotechnician, and Viggz Shinesparked.
If you have and engineer with a skill level of 335, you can buy Schematic: White Smoke Flare from Captured Gnome, Feera, Wind Trader Lathrai and Yatheon.
The Schematic can be bought for 6 gold from the vendors and sold for 50-200 gold in the Auction House.
