Rollick knelt down to check out the shards of transparent plas-crete embedded in the floor. They were mostly about 1-3 centimeters in length, half a centimeter across, and pointy to the touch. [Ouch!] Really pointy. Rollick sucked on the wound on the tip of his finger. Plas-crete, especially transparent plas-crete always sharded when it blew. The question was, what made it blow? A material that was strong enough for pressurized steam tubes in a fusion reactor wouldn’t blow for anything less than a professionally shaped C6 charge. And that narrowed down the list to a handful of people, all of whom Rollick knew, or knew of, and governments. Wonderful. It was that kind of day.
