Artemis- High-Tech Hide

  The hide was ingenious in design and interest had already been expressed in the manufacturing rights — mostly by military representatives — but Artemis had resolved to sell the patent to a sporting-goods multinational. It was constructed of an elasticated foil polymer on a multi-hinged fibreglass skeleton. The foil, similar to that used by NASA, trapped the heat inside the structure while preventing the camouflaged outside surface from overheating. This ensured that any animals sensitive to heat would be unaware of its presence. The hinges meant that the hide would move almost like a liquid, filling whatever depression it was dropped into. Instant shelter and vantage point. You simply placed the Velcroed bag in a hole and pulled the string.
