In my childhood, I remember there was a cartoon on tv called "Blade Blade". It was about a bunch of kids playing spinning top, though a more sophisticated version of it, with different sorts of powerful creatures in it that would be evoked once this modern whipping-top was flung. It was a total fad back then. You could find this products to buy everywhere you went to, even on shelves in supermarkets. But, I've never had one. Instead, my friends and I personalized one of these authentic whipping-top nailing nail tips around it, so it'd spark when it hit one another. We would play the whole morning, throwing them onto a large metal basin in my front yard. It was lots of fun. sembra naturale?
