A computer is here, currently turned on. Igor is here, fidgeting nervously. Nothing happens for several strainful seconds. Then the crank moves a little bit, and a little more, and slowly a crack in the ceiling widens. Inch by inch the ceiling opens, until it completely disappears.
Rain pours into the laboratory.
Igor looks at you expectantly. IGOR Igor devours the biscuit greedily. Igor nimbly climbs the rope and crawls outside. You spit on our hands, take a deep breath, grit your teeth and heave on the crank. It grudges a little bit.
