My juggling friends know that for the most part I’m not a huge diabolo guy. But I like to think I can appreciate when I see someone doing amazing diabolo work. It wasn’t that long ago I first saw someone doing multiple diabolos in vertax (where the axis of the diabolo is vertical rather than horizontal). Now, here we have Alexis Levillon taking this a step further: doing multiple diabolos while one is in vertax and another isn’t. I would have thought physics would have had something to say about that. Apparently not. Good stuff.
