Cash Flow

Cash Flow is an Uncle Scrooge-adventure comic written and drawn by Don Rosa from 1987 and first of his stories where the Beagle Boys appeared. Like some others comic stories by Don Rosa (such as A Matter of Some Gravity and The Universal Solvent) that story is founded in toying with laws of nature. Rosa thinks that he has got ideas for those comics from mechanical engineering course of institute of higher education, which he took before he became to professional cartoonist.

Plot
To make their chores to rob the Money bin easier, the Beagle Boys acquire an anti-inertia and anti-friction beam pistols from the foolish cabbage professor who invented the petrifying beam. Next, they march to the Money bin and evade all obstacles with their beam pistol, including a barbed-wire fence, dogs, portcullis, automatically triggered machine gun nests and cannonballs. They advance in that way as far as towards the strongroom.

There Scrooge snatches the anti-friction pistol and fires it at the money, making it behave essentially as a liquid. The Beagle Boys are disappointed when they find that the money masses are too slippery to carry. They tie up the ducks, leave the beam pistols and go out to punch holes in the wall of the Money bin. At that time Ducks exploit the situation and they free themselves from the ropes with the help of the beam pistols. Scrooge hurries to the roof terrace and shoots anti-inertia at the tools of the rascals, so that they have no effect on the bin wall.

At last the Beagle Boys catch on, and attack simultaneously with many bulldozers. At the same time the beam gun runs out of power, and the excessive use of the ray guns has weakened the concrete in the walls. The bin cracks like an egg, and the money masses wave over Duckburg and wash down the drain network owned by Scrooge. The Ducks leave to rescue the money with Donald Duck's car, that has become amazingly fast because the deletion of inertia. The money is caught on barges and carried back to the Money bin, Scrooge shoots the Beagle Boys with both beam pistols and then shoves them into prison with a flick of his finger.
