Recently a study of the rst superposed mechanical quantum object(\machine") visible to the naked eye was published . However, as weshow, it turns out that if the object would actually be observed, i.e.would interact with an optical photon, the quantum behavior shouldvanish. This, the actual observation, has long been suspected in manyinterpretations of quantum mechanics to be what makes the transitionquantum ! classical, but so far it has not been available for direct ex-perimental study in a mechanical system. We show how any interaction,even a purely quantum one, of sucient strength can constitute a physi-cal \measurement" - essentially the emergence of an eectively classicalobject - active observation thus being a sucient but not necessary cri-terion. So it seems we have in this case of the \quantum machine" aunique possibility to study, and possibly solve, the long-standing \mea-surement problem" of quantum mechanics.
