Top spinning on a tip
« on: December 20, 2018, 04:46:34 PM »


This is Tony Stein playing with one of his tops. 
The top spins on a tip.  I am wondering whether this is possible or there is a trick.
Maybe the tip of the top is holed ? What do you think ?

I'm thinking small dimple in end of the tip on the top, plus some skill.

Who is this guy, anyway? I love that he does quirky/artsy things with some pretty cool quirky/artsy tops. Is he famous for something, or does he just present himself that way?

I agree, I think there is a very small dimple in the tip. But, of course, Tony's tops amazing balance makes the trick possible.

Jeremy: although his YouTube videos don't seem to have many views, he has appeared numerous times in South Africa media showing his tops.

Yes, there must be a small dimple, I wasn't totally sure but it makes sense.

There was a video interview to Tony but I can't find it.  He makes his tops, and he puts attention to very good balance.
He said he uses stickers to fine tune the balance of them.  They are not only for aesthetics.

Makes sense -- even tiny wobbles of any kind would make his tricks impossible. Dynamic (static + couple) balance, tip alignment, contact shape, and structural rigidity would all have to be near-perfect. That's a tall order for any real top, but one you've pulled off many times.

Some of those stickers are pretty trippy. Betting he was once a hippie or a rocker.

You can actually see the dimple in the video. But yea, that’s some serious balancing skill!

Once you have all in place the balance is very much like the giraboli (but way more impressive) dont you think??

It's funny that they would have a specially marked pen for the Giraboli. I'll try to get one when I visit Trompo Space in May.
I never asked Gerardo (or was it Pulp or Javier Caballero the inventor?) if he was inspired by Pencil Sharpener.
