"Yyyyyeah..." replies Artair. "I think they took the shrink ray with them. So it might have been left on. I don't wanna go too close to it... Or... Actually, no-one else should go near it. I should be safe, because I've been hit before. It can't remove any more mass from my body, so I can go over there and collect anything made smaller by the ray's radius. Could you take off the door for me, please?"
