As you watch the chaos below, you note that there barely perceptible grooves presenting both horizontally, vertically, and diagonally throughout the metal plate which this city stands on, upon your desk. Some of the sections are square, some oval, some even triangular. Curiously, and without much concern for the damage you cause, you bring forth one of your thumbs and drive your thumbnail underneath one section. Then, you reach your other hand over and use your other thumbnail to separate the opposite section. With both thumbs, you push the two neighboring sections in opposite directions. You do try to avoid senselessly destroying any of the buildings but as you succeed in separating one section from another, a couple buildings unavoidably topple over from the instability your movements cause. However, you successfully break away one section from the whole of the miniature city. The metal plate acting as the section's foundation is sturdy and small enough to fit in your palm. The section you separated is circle-shaped, unlike some of the others which are square, triangle, or oblong. If you had to guess it is about an inch in diameter; small enough to fit inside a petri dish.
What should you do with this city-section, you think. You notice next to your bed the pair of overturned sneakers you were wearing most of today. Perfect. You bring the city closer in, right up to your face. "Hey you tiny aliens; you guys want to go exploring? I've got an idea for you!" You give the city-section in front of your eyes an excitedly cruel grin.
Then, with your free hand you pick up one of your smelly running shoes that you wore today; you inspect it briefly. Dirty and grass-stained, this prison will do nicely!. Although you are a pretty well-groomed and clean guy, there isn't much you can do about the all-day smell of your feet that permeates your sneakers due to your competitive running. Actually, you're sort of proud of how they smell. The more they stink, the manlier you feel.
"You little guys are lucky," you state. "You're going to be experiencing an environment like no other that exists anywhere! You might make discoveries that could prove earth-shattering back home! It's a semi-enclosed environment, and unfortunately I'm just too big to experience the intricacies of this habitat. But from what I have smelled of the, uh, flora and fauna within, I can say without any doubt that it's quite a complex and robust ecosystem. Definitely a unique one! Maybe your scientists can grow something out of what's already growing within it!"
You let out a rather sadistic laugh as you bring your giant shoe up with one hand and lower the city-section down into the humid, cavernous interior. You lay the section, which is about the size of a quarter, gently on the damp, worn fabric insole and gently nudge it toward the toe section of your sneaker where it is darkest and most humid. You grin wickedly; within your sneaker is an entire city-section of intelligent beings; hundreds of civilians and families, maybe more, forced to endure the smell your feet have created within. At your colossal scale, the miasma within your running shoe must be overwhelming to these little microbes, you delightfully think. You've run in these sneakers for a couple years now; who knows what vast numbers and varieties of moisture-loving microbes have made their home inside of your footwear.
You fantasize about how their historians, generations from now, will document and and describe the period wherein their city was seized by a giant teenage alien and then made to languish within the giant, evil teen's stinking sneaker: an embarrassing era for them to be sure! You also excitedly wonder if the noxious environment created by your feet may be truly harmful to your little slaves. You can just picture them all wearing gas masks right about now!
