This spinning LEGO blacklight show is really meant to be seen in person. Video hardly does it justice, and phone camera stills aren't much better. But what you do see here is entertaining enough that I'm sharing it anyway. In person, the tree colors change with spin rate, which here reaches 550 RPM in 7 steps. Around 300 RPM, the orange and green start mixing to yellow. By 550 RPM, you see a completely yellow tree encircled by blue and white rings -- the white coming from mixing the yellow with the blue. (Additive color-mixing rules apply.) The small 3-bladed propellers are worthless for boat propulsion, but they really shine for their size under blacklight. Minifig heads emit the blue. The tree holds its shape and balance reasonably well at top speed. The tolerable wobble peaks at intermediate speeds. I'd love to report that the inverted tree works as a spinning top. But centrifugal force would surely rip it apart long before it reached operating speed. Besides, air resistance would quickly bring it down.

Looking for fellow LEGO top-makers here on Eurobricks. Very little posted on this building genre so far, but I'd very much like to change that. Special Themes seems to be the best fit. Over the last 2-3 years, I've designed and built at least 1,000 working tops and still have well over 700 in my collection. As you can see from my MOCpages top folder and the videos below, the visual and mechanical design possibilities with this simple kinetic art form are truly endless -- especially in the LEGO realm. Since tops are mostly about motion, I'll embed a few of my less conventional spintop videos as an introduction. No need to watch any of them all the way through. Yuri Fassio held annual top-making contests for several years on MOCpages, ending ca. 2012, but there was never much activity between contests, and all but a handful of the tops posted there in recent years have been mine. It'd be nice to have some company.
