Test the limits of your powers

Sophie: "Now I gotta wonder: what's up with this quirk of not breaking anything? Seems kinda uncharacteristic of a Giantess."

The GWR building which you just shook and rattled like a maracas remains in perfect condition. Not even water or electricity are severed now that you placed the thing back to its original place. Jude, who by all means should have splattered against the concrete, is already upright and functional after her dizzying experience.

Clearly there's something weird going on. Ever the inquisitive mind, you decide to experiment. A red car on the side of the road catches your attention.

Sophie: "I wonder if I'm unable to break anything, even intentionally?"

You stomp your foot onto the flimsy vehicle with all hundred tons of your mass. You feel it flatten.

Sophie: "Aww hell. Should've tried this with something less expensive..."

But, as you lift your foot, the car seemingly bounces back into form as if spring-loaded. Not only is it intact, but getting crushed has given it a nice, sleek form reminiscent of a sports car. The car's owner, who apparently had been inside, climbs out from the front seat and rejoices as his lumbago is cured.

Sophie: "O-ho-kay... yea this is clearly just plain magic. Let's try a different scale, then."

You resolve to grow twice as tall, until large apartment buildings only reach to your waist, and you dwarf even the largest skyscraper in the city. Here's where a little introspection could go a long way: exactly as just a moment ago, you're using possibly unfounded leaps in logic to justify **** risk of destruction, but... as much as you are inquisitive, you are also reckless.

Arms spread wide, you fall backwards onto about twenty city blocks. You wave your arms and legs, making a city angel. Initially, it feels like you've destroyed everything in your wake and probably killed ten thousand people.

However, as you get back onto your feet, you see that you've left behind a pristine, beautiful park shaped like yourself. All the buildings that once occupied the space were moved to the sides, creating sensible avenues that fit perfectly into the pre-established gridlock pattern of the city's layout. Those buildings that couldn't fit anywhere else were placed on top of each other, joined together into taller versions of themselves, or even turning bungalows into strange-looking but structually sound apartment buildings.

Sophie: "This is mental! I'm a giantess, but I don't have to watch out for anything anymore."
