As reported in the New York Times, mystery chemicals will be burned in cartridges at the Vatican to let the world know via chimney-smoke whether a new pope has been chosen.
Black smoke = no new Pope.
White smoke = new Pope!
What 3 Other Colors Of Smoke Emerging From A Chimney At The Vatican May Mean
1. Greenish-Yellow Smoke. The color-producing cartridges were manufactured with budgetary considerations in mind, in Wuhan, China using the city’s yellowish-green smog.
2. Blue Smoke. Instead of reporting a new Pope hire, someone at the Vatican is about to be fired for making smoke the same color as the sky, leading to more spectator confusion!
3. Red Smoke. A new Pope has not been chosen, but enjoy this smoke advertising the remake of Red Dawn, now on DVD!
