"The rules for this challenge state that the cone has to have a diameter no greater than 9.5 cm (3.74 in) and that once all the scoops are balanced, they must remain on the cone without falling for a minimum of 10 seconds."
Ten seconds is a long time! (Ask my girlfriend.)
Still, most of us probably wouldn't have that much luck, as Panciera is a professional... I guess. And, he claims his success is a direct result of using gelato made locally. So you might have to buy a plane ticket.
If you want to see more of Panciera's love of giant ice cream (and why would you not?), here he is with the world's largest ice cream scoop, also his creation. I'll leave you guys alone.
