This rotating-top-inside-a-top is making my head spin! - Yanko Design

Perhaps the well-nigh interesting matter to happen to tops since the Beyblade (perhaps more interesting than the Beyblade itself), this is the Topsy Turvy Top, conceptualized and designed by Lee Krasnow, and shown off in the video in a higher place by gorging YouTuber, Michael Stevens. The manner the top works is rather interesting. The design contains an outer and an inner top. Get the outer top to spin and the inner pinnacle spins too, because it'south being held by the outer acme. At present flip the outer height over and finish its spinning and the gates at the base of operations of the outer top open up in grand manner to reveal the inner meridian that continues spinning after the outer top has been stopped.

Designed to display the inertia of move equally well equally centrifugal forces, Krasnow'southward tiptop is a fun, educational 3D printed toy. With a handful of parts that can either be put together on your own, or bought assembled from Krasnow's Etsy store, the Topsy Turvy Top does a wonderful job of displaying the transfer of forces of energy, and the video above even breaks downwardly the centrifugal forces that crusade the gates on the larger height's base to swing open, and the inertia that causes the inner pinnacle to remain spinning. It'due south worth noting that the inner top tends to spin in the aforementioned management as the outer i, even when you flip the outer top upside downwards (causing information technology to spin in the opposite direction). Suck on that, fidget-spinner-that-does-cipher.
