Huh...Maybe if I could take it apart, I can figure out how it actually works and make more of that particular device... All right, enough with playing with the rules. Actually, I'm quite happy with my actual size. I think being small or big would make it harder to get along in a big city like the one I live. I don't really find it too practical to do either. So I think I would pass the opportunity.
Still, I think I could make much money out of that device.
Though one, but there are more advantages at being tiny, like slipping between small gaps and such. Maybe even being able to see atoms and all that small stuff. Only bad thing may be that insects are enormous now
