Yes, that was funny! ;D

He calls it with the Spanish name trompo, not the German kreisel. But the shape is closer to a Chinese tuoluo.
In fact, from the way he tries to start it, I bet he was inspired by the videos of Lin Sen Hai starting his giant Taiwanese top. Maybe from one edited with a Spanish title.  ::)

Hilarious! A for perseverence, D for learning from mistakes.

Beautiful demo of the main reason that LEGO show visitors fail with my finger tops: Way too much focus on getting the top up to speed and way too little on keeping it upright -- especially at the moment of release. Telling them to back off on the torque and keep the top as vertical as possible is usually all they need to succeed -- at least with my easier tops. (The hard ones require fine tilt control at high torque -- a combo that only comes with practice.)

So at least our video heroes are in good company: My more motivated but less practiced visitors tend to crank hard and fail over and over and over until I intervene. 

Addendum: From the success at 2:44, we see that the drill had the torque vs. speed curve needed to get the top well above critical speed. The failures with the drill were mainly from inadequate tilt control near release.

To be charitable, maybe their later abandonment of tilt control in favor of even more speed was their way of demonstrating the value of tilt control.
