With the changing season, it's common to light a few candles to fight the cold and the winter blues. But why use a candle when you can create your own multicolored flame tornado? Do you have unused glass vases and empty tea-light tins laying around the house? Then you have all the necessary materials to make a jaw-dropping flame tornado.
According to David Grossman from Popular Mechanics: "The fire tornado is already cool on its own, and way easier than building a giant tornado with a bonfire and box flames. What's more is that by adding chemicals like lithium to produce a red flame or boric acid to produce a green one, it's possible to generate a tornado that's multiple colors at once. The effect is certainly eye-catching but you might be better off not setting a bunch of chemicals on fire. And if you do, at least do it out in the backyard."
