Get a large (5lb or larger) coffee can, a votive candle, chopsticks (2), an industrial coffee filter (the extra large one used in restaurants), a flour sifter and one large container of powdered creamer.

Place the candle in the bottom of the coffee can with a hole in the side so you can light it (also for ventilation). Place the chopsticks on top of the can in an X shape and lay the coffee filter over the top. Position the candle so that the flame isn’t directly underneath a chopstick, you want the heat to reach the filter. Using the sifter, sift the creamer onto the filter over the candle. Light the candle and gtfo. At least 100ft (approx 35m) as the resultant fireball should be large. Make sure to do this in a large open field far from anything of value and with adequate fire protection present.
