"I don't know what happened!" Captain Samantha Carter yelled over the screaming alarms, blinking to clear her eyes of the smoke that was settling around the room.

"Well figure it out, Carter!" Colonel Jack O'Neill replied, picking himself up off the floor. Looking around, he could see that most of the damage was concentrated around the alien device sitting on a table in the middle of the room.

"The device appears to have remained intact, O'Neill." Teal'c remarked, as calm and objective as always. Jack looked around the room for the fourth member of their group, Daniel Jackson.

"That's great, Teal'c. Anyone seen Daniel?"

"Over here, Jack." Daniel groaned as he attempted to push a fallen bookshelf off him. He maneuvered the bookshelf off his lower torso, and winced as he stood.

"You okay?" O'Neill asked as he lent Daniel a shoulder to lean on.

"Just twisted it; I'll be fine." Daniel answered after testing his weight on his ankle.

"Colonel," Carter called out, "I think this is some sort of percussion grenade. Obviously reusable, but I can't figure out how we triggered it."

"Well I don't want to take it back through the gate with us until we know what sets it off." O'Neill decided.

"Uh, Sam?" Daniel piped up, looking worriedly at the device, "I don't think finding its trigger is such a great idea."

"Why not, Daniel?" Sam asked, recognizing the look on his face.

"What if you set it off, and it's like a Zat-gun?" Daniel pointed out.

"One shot stuns, two kills?" Sam asked, realizing the implications and looking at the device a bit more cautiously.

"And three disintegrates." Teal'c added.

"D'ya think?" O'Neill asked, sighing dramatically. Before anything else could be decided, Teal'c noticed a small control flashing on one of the screens by the wall of the laboratory. Pressing it, the screen came to life.
