"Modern science fiction is the only form of literature that consistently considers the nature of the changes that face us, the possible consequences, and the possible solutions."
- Isaac Asimov

| A bladder-like device that both finds and temporarily fixes leaks in moon tunnels or space station habitats. |
You're in a space station or habitat in a vacuum. One of the most serious dangers you face is the loss of air; how can you find and fix leaks?
| There were perhaps a dozen bladder-like objects in the tunnel, the size and shape of toy balloons. They seemed to displace exactly their own weight of air; they floated without displaying much tendency to rise or settle. Konski batted one out of his way and answered me before I could ask.
"This piece of tunnel was pressurized today," he told me. "These tag-alongs search out stray leaks. They're sticky inside. They get sucked up against a leak, break, and the goo gets sucked in, freezes and seals the leak." "Is that a permanent repair?" I wanted to know. "Are you kidding? It just shows the follow-up man where to weld." |

This is such a simple solution to the problem. The slow leak of air causes the balloons to move to the source of the problem. When they are sucked up against the small hole, they are popped, releasing material to stop up the leak.
Obviously, this would only work with small leaks.

The tagger's dream - lie in bed while painting at a remote location.
'... as though a child should build from nursery blocks a fantastic shape which abruptly is filled with throbbing life.'
'... the immense, three-dimensional, minutely cubed model...'
