A cylinder of close-packed beans rested on the bench under the opener.

The can itself had disappeared.

"Chief," said Hanson. "Chief."

"Yes," said Feetch. "I see it too. Try another can."

"Vegetable soup or spinach?" inquired Hanson dreamily.

"Spinach, I think," said Feetch. "Where did the can go, do you suppose?"

The spinach can disappeared. Likewise several corn cans, sweet potato cans and corned-beef hash cans, leaving their contents intact. It was rather disconcerting.

"Dear, dear," said Feetch, regarding the piles of food on the bench. "There must be some explanation. I designed this opener with sixteen degree, twenty-two minute pressure angle modified involute gear teeth, seven degree, nineteen minute front clearance cutter angle and thirty-six degree, twelve minute back rake angle. I expected that such departures from the norm might achieve unconventional performance, but this—Dear, dear. Where do the cans go, I wonder?"

"What's the difference? Don't you see what you've got here? It's the answer! It's more than the answer! We can put this right into work and beat the dead-line."

Feetch shook his head. "No, Hanson. We're producing something we don't understand. What forces have we uncovered here? Where do the cans go? What makes them disappear? Are we dealing with a kinetic or a kinematic effect? What motions can we plot in the area of disappearance and what are their analytical mathematical formulae? What masses may be critical here? What transformations of energy are involved? No, Hanson, we must learn a lot more."
