Hurricanes are huge circular storms of wind, clouds, and rain that form over warm tropical oceans.
The clouds in a hurricane can be seen as circular bands that spiral around a hurricane's eye. You can duplicate the swirling motion around the calm eye of a hurricane. Moving the spoon in a circular motion around the side of a bowl, stir the water. When the water is moving fast, stop stirring and immediately put several drops of food coloring into the center of the swirling water.
