It is a warm spring night in old Paris, and the lab lamps are still burning. Pixel Marie Curie has spent the whole evening on one patient experiment: a batch of little round flasks that shine with a soft, perfectly safe green glow. They were lined up on the windowsill to cool when a playful gust of wind swept them out over the rooftops, where they now drift like tiny lanterns among the chimneys, a sight the night watchmen would surely call Rooftop Glimmer. Without them, months of careful measuring would have nothing to show, and the whole city is asleep, so nobody else is going to fetch them.
Luckily, the lab has a secret: a small pedal glider with canvas wings, a spinning nose propeller and a lantern of its own. Every push on the pedals lifts it a little, and gravity takes care of the rest, so the trick is a steady, unhurried rhythm, just like in the lab. Ahead, the skyline is packed with brick chimney stacks, slate mansard towers with lit dormer windows and tall iron lattice towers. Every flask she catches is one more glowing result saved for the morning notebook, so how many can she bring home before sunrise?
