When rain is falling lightly outside do the following:
On a flat surface such as a pie pan or cookie sheet, sprinkle an even layer of powdered spice, such as cinnamon. When the surface is completely covered to an even depth take it outside and stand in the rain. Ask your question and then run back inside. The raindrops will have disturbed the spice to etch patterns or symbols into it. Sit quietly and gaze at the spice until you have perceived the answer.
