Space Gel

TKG12 We Have Contact/16

Yollin invention. A gel which expands and freezes in vacuum, quickly closing any hole punched in a space craft. Outer shell would jettison when craft left, leaving hole to close slowly, possibly killing any creatures who might be alive in the holed vehicle. Used in space encounters, when a ship either attacks another ship and boards it, or a meteoroid might puncture a ship's hull.
