Correction: If you want something Unique and Cool, and try gooping a few things, at least one of them will amost certainly be Unique and Cool. There is absolutely no guarantee (or, even, any particular likelihood) that it will follow your desires as to *specific* varieties of Unique and Cool. Attempts to exactly duplicate existing Unique, Cool things are almost certain to fail. Attempts to duplicate devices that provide Basic Fundamental Needs will generally be successful (almost always after two or three tries, if the first one didn't work) but always have some particular bit of character about them that makes them Not Quite Like Any Other.
There are ways around this, of course, and exceptions. Handwavium is *all* *about* loopholes... but none of the ways around are perfect, and none of the exceptions are guaranteed to be repeatable.
