More tops from Tim
« on: February 12, 2020, 10:37:19 PM »

Tim's been showing a lot of tops lately...

Here, he features the "Non Toppling Top" first discussed here on this forum and still sold as the Balancing Taorenado on Spingear.

These look like a lot of fun. I've made LEGO tops with similar behavior. They just don't stay up as long. (It's all about dialing in the right CM height and TMI/AMI ratio with the right ball tip. Tim states at 0:48 that a "physics friend" told him that the top's resistance to being knocked over is due to a "very low center of gravity". But my experiments show otherwise. Too low or too high a center of gravity, and you don't get this behavior.)

And from the 2020 Nuremburg Toy Fair, first a spindulum featuring a hanging, spinning globe. Then some interesting true tops...

Enjoy!
