A funnel system and method for introducing and dispensing a material are presented. In this funnel system two frusto-conical devices having intake ports which have a larger diameter than the diameter of their exit ports may be mated. When mated, a passage exists through the devices' exit ports. Both frusto-conical devices may have partially eclipsed exit ports such that when one device rotates with respect to the other, the passage throttles between a substantially open and a substantially closed position. In this method the devices may be rotated such that the passage may be in the substantially closed position and a material may then be introduced into the second device's intake port. To dispense the material, the devices may be rotated such that the passage may be in a substantially open position whereupon the material may be dispensed from the first device's exit port.
