"We figure this will save you a lot of money in construction work," Bill said. "You can get along without riveters. You just have a man put holes in girders with this and push the rivets through. You also make holes for the beam-ends, and your entire building will be anchored in the fourth dimension."

Blair asked, "You say you two invented this gadget?"
"That's right," Bill said. "We've got a workshop in my basement. We invent in the evenings after we come home from work."

"I suppose you want money for this thing."
"We'd like to sell it, yes, sir."
