"As you can see i'm wearing some pretty stretchy clothing right now, and that's because i've got this weird little remote, ray... whatever thingy that expands bodies in odd ways. Apparently the inventor got the idea when he read a sci-fi model about shrinking. Something about most atoms being made of empty space with the electron cloud, and thought about instead of shrinking that electron cloud he'd make it expand... I don't totally get it, but if I select some body part... or something... then fire it'll grow... Although because of that electron cloud thing isn't that stable it only lasts maybe a minute or two before you shrink back down, but I bet you growth fans are in it for the process so having it reset and doing it over and over again should seem fun. So what should I do with it? Any challenges?"
