I’d have to see it to believe it. A second is actually a lot longer than it feels. So unless it’s on video, when people tell me anything longer than 5 seconds, I always imagine what they really meant was, “it did a finger grind for a LOT longer than I can normally grind for! It was amazing!”
And it may have felt like 10 seconds. But without a video, I just can’t bring myself to believe it.
Starting 2:42, this is what 5-6 seconds of grinding looks like. It’s a pretty long time if you imagine that the trick was happening in realtime, but it’s barely more than half of the 10 second claim. That’s if it was realtime, but the video is in slow-mo. You can see the spin dying, and that’s around 3 seconds of real time. That includes hops, during which friction is relieved. Over 3 times that much grinding with friction the whole time? Show me the video.
A 3 second grind is pretty normal, and I’m sure if it wasn’t for wanting to make sure there was a good “take” (the hopping was the important thing) Mike could have gone for longer. But 10 seconds?
Not to mention that as the spin dies, the gyroscopic effect dies. Then it’s not just spintime and friction, but the ability to balance a slowly-spinning object on your finger.
For palm grinds, you can actually do it with just one rim if you’re clever, but you need full speed; it doesn’t work when the yoyo starts to die. Traditionally, there are two rims, which can create a lot of friction especially with a semi-organic shape like the Chief.
Suffice it to say, some skepticism over here.
