I agree it is hard to believe the inverting process. It is easier to explain with you having the pictures. The upper portion of jug..... the funnel, was an intermediary piece in the filling process..... the missing transition piece screwed into the basin, the funnel piece attached to the opposite end of the transition piece, and then the funnel threaed onto the jug with the plug removed. During preparation the jug was in its normal orientation, base down.Other pieces was inverted. Then all were rotated for the fluid to flow into the basin.....maybe.
