funnel is slow. Provide four openings at the bottom instead of one. A small rubber hose will connect the opening of each barrel, and a cut-off or a string attachment at the end of each hose cuts off the flow when the barrel is full, and permits the contents of the hose to be carried back to the barrel and thence into one of the unfilled barrels, thus avoiding waste.
