Topsy Turvy

thingiverse

This massive spinning top conceals an ingenious mechanism which, when triggered during its rapid rotation, unleashes its six delicate petals, liberating the tiny top hidden within. With time and persistence, it becomes possible to skillfully activate the release mechanism while Topsy Turvy is whirling at top speed and inverted in such a way that the mini-top continues spinning even after the main body has come to a complete halt, as vividly demonstrated in the following video.
