"[Science fiction] has become big business, where books are merchandised and promoted and distributed and placed on sale like slabs of bacon or cans of soup."
- Frederik Pohl

| Breathing Balloon | ||
| Like a helmet, but rather than being solid it can pass some gases. |
| When next he left the extension cage, carrying the flight stick, Svetz was wearing another spin-off from the interstellar-exploration industries. It was a balloon, and he wore it over his head. It was also a selectively permeable membrane, intended to pass certain gasses in and others out, to make a breathing-air mixture inside.
It was nearly invisible except at the rim. There, where light was refracted most severely, the balloon showed as a narrow golden circle enclosing Svetz’s head. The effect was not unlike a halo as shown in medieval paintings. But Svetz didn’t know about medieval paintings... The horse screamed as it went into free fall. The horn, intended for Svetz s navel, ripped past his ear and tore his breathing balloon wide open. |
