"It'll be a problem," Mr. Swift conceded. He finished his coffee, then looked up with a twinkle in his eyes. "How about figuring out a solution for me, Tom?"
"A new kind of air lung?" Tom was intrigued!
AERIAL ATTACK
"Yes, son," Mr. Swift went on. "What's needed is a new type of breathing device—one that will eliminate bulky air tanks and permit a skin diver to stay down for long periods."
"Quite an order, Dad."
Grabbing a pencil, the young inventor began sketching. In both his Fat Man suits and his osmotic air conditioner, Tom had already perfected ways of drawing oxygen from sea water.
"But a small gadget for skin divers," he said, "will take a fantastic job of electronic miniaturization." After a pause he added, "It could really speed up recovery of the Jupiter prober, though."
Lunch over, Tom hopped a jet scooter and sped off to his private laboratory. The modernistic glass-walled structure—designed by Tom himself—had every tool of modern scientific research, from electronic microscope to helium cryostat.
